To investigate the effect of surface area

to investigate the effect of surface area This experiment aims to prove that surface area may not be a factor which affects the frictional force acting between surfaces many primary school teachers tend to tell the students that as the.

Usually the surface of the water is covered with oil (eg cooking oil) to prevent evaporation from the water surface the whole apparatus can be weighed and the loss of mass represents the loss of water from the leaves. • to investigate the change in surface area to volume ratio with cell size • to investigate the effect of a change in the surface area to volume ratio on the rate of diffusion • determine how surface area and volume relate to one another. For this investigation, the effect of the temperature of water upon the rate of cooling will be investigated the temperature-drop over 5 minutes (600 seconds) will be measured for 200ml of water at different start temperatures. Therefore, this study intends to investigate the effect of concentration and surface area of reactants on the rate of chemical reactions magnesium metal (in form of a ribbon or powder) reacts with acids rapidly than water liberating hydrogen gas.

To investigate the effect of surface area on the rate of reaction using the enzyme catalase, found in potato, and the substrate hydrogen peroxide. Effect of osmosis rate on different surface areas, depending on different types of water solution an investigation showing the effect of surface area on osmosis rate, including some different types of water concentration. Increasing the surface area by finely crushing solid reactants increases the rate dramatically as a result of more successful reactant collisions per second this technique has many practical applications where a fast rate of reaction is essential. An increased surface area to volume ratio increases the rate at which water diffuses through a plant as the surface area to volume ratio increases, the cell becomes thinner allowing for a shorter diffusion pathway hence, creating a more rapid and efficient diffusion of water across the cells.

The objectives of this experiment was to calculate the surface area to volume to ratio of pieces of agar and determine what effect this ratio had on the rate of diffusion. The villi vastly increase the surface area of the cell whereas the cell which is round only has a small surface area in relation to it’s volume both cells above have an volume of 1cm³ the cell on the left has a surface area of 3cm² but the cell on the right with villi has a surface area of 10cm². International baccalaureate biology tutorial 216 explain the importance of the surface area to volume ratio as a factor limiting cell size. If at least one of the reactants is a solid, the reaction proceeds faster if the solid is finely divided because the surface area is larger in a finely-divided solid, exposing more of that reactant to the other reactant or reactants for example, a 50-pound bag of flour is essentially inert because the flour, although finely ground, exposes little of its surface area to the air.

The other factors that affect evaporation are surface area, temperature and air movement you can do a few fairly simple experiments to demonstrate the effect that the various factors have on the rate of evaporation. Determine if there is a relationship between leaf surface area (ie, the total number of leaves or the size of the leaves found on a plant) and transpiration rate the guiding question of this investigation is, how does leaf surface area affect the movement. 417 describe experiments to investigate the effects of changes in surface area of a solid, concentration of solutions, temperature and the use of a catalyst on the rate of reaction 417 describe experiments to investigate the effec.

Surface area there are at least two ways of estimating the effect of surface area there are at least two ways of estimating the effect of surface area an added extra dimension would be to try to establish if the upper or lower surface is more important in transpiration. Relationship between surface area and rate of reaction essay - an experiment to investigate the relationship between surface area and rate of reaction introduction the rate of reaction (reaction velocity) may be defined as the rate of change of concentration of a stated reactant or product. How does surface area affect a chemical reaction if one of the reactants is a solid, the surface area of the solid will affect how fast the reaction goes this is because the two types of molecule can only bump into each other at the liquid solid interface, ie on the surface of the solid. Investigating the effect of surface area a cut three 5 cm lengths of rhubarb leave one piece as it is, cut one piece in half lengthways, and cut the third piece into 4 evenly-sized pieces. Surface area to volume ratio and the relation to the rate of diffusion essay sample aim and background this is an experiment to examine how the surface area / volume ratio affects the rate of diffusion and how this relates to the size and shape of living organisms.

To investigate the effect of surface area

- an investigation into the effect of surface area on volume ratio on the rate of heat loss heat loss from an object is affected by its surface area to volume ratio (sa/v) the smaller the sa/v the faster heat is lost by conduction, convection and radiation. The rate of a chemical reaction strand nomenclature, chemical formulas, and reactions topic investigating chemical reactions and equations primary sol ch3 the student will investigate and understand how conservation of energy and effect of surface area on reaction rate: in a solid, only surface particles can interact with the other. The ratio of surface area to volume strand life at the molecular and cellular level bio4 the student will investigate and understand life functions of archaea, bacteria, and eukarya key concepts include the effect of surface-area-to-volume ratio on the rate of diffusion. The effect of surface area can be determined by recording the time taken for the reaction to occur the rate of reaction will increase when the surface area of the reactant increase in addition, there have two ways in order to find the effect of the surface area of the rate of reaction.

  • The purpose of this study was to investigate the influence of tablet surface area/volume (sa/vol) on drug release from controlled-release matrix tablets containing hydroxypropylmethylcellulose (hpmc.
  • To help students better understand the concepts of surface area, volume, and surface-area-to-volume ratio, have them build models with plastic centimeter cubes physical models can help make these ideas more concrete.
  • To observe the effect of surface area (particle size) on the rate of reaction between marble chips (calcium carbonate) and hcl 3bto observe the effect of surface area (particle size) on the rate of reaction between magnesium ribbon and hydrochloric acid.

Their data analyses reveal the importance of weight to normal friction (the friction that occurs as a result of surface roughness) and the importance of surface area to the friction that occurs between smooth surfaces due to molecular attraction. Class practical this activity explores factors which affect the power output of a solar panel, and may lead to an investigation of quantitative aspects of some factors. How can we investigate the effect of particle size/surface area on the rate of a reaction how does the changing the particles size (changes surface area) of a solid affect the speed of a reaction why does changing the particle size or surface area change the speed of a reaction.
