The Effect of Molecular Weight on the Diffusion Rate of Substances Jesselyn P. Rodriguez Group 4 Section X-2L August 13‚ 2013 ------------------------------------------------- ------------------------------------------------- ------------------------------------------------- ABSTRACT The effect of molecular weight on the rate of diffusion of substances is tested using two tests: the glass tube test and the agar-water gel test. In the glass tube test‚ two cotton balls were soaked

Chemistry 1061: Principles of Chemistry I Gas Laws Gas Laws: Pressure‚ Volume‚ and Temperature Introduction Pressure‚ volume‚ and temperature are properties of gases that reveal their relationships when any one of them is varied. Changing the temperature of a gas may change its volume or pressure‚ but how? What are the mathematical relationships between these properties? Are there limits to them? Scientists have discovered through the study of properties of gases that there is indeed a theoretical

Practical to Investigate Diffusion and Osmosis Collect the following equipment: 1x beaker 1x length visking tubing 1x pipette 1x pair safety glasses Instructions – always wear safety glasses! 1. Fill your beaker ¾ full with water 2. Tie a knot in one end of your visking tubing 3. Using your pipette‚ transfer some concentrated sugar solution to the inside of the visking tubing‚ leaving enough space to tie a knot in the open end 4. Add a few drops of red food colouring to the inside of the visking

Practical 6 -Determining the Gas Constant Aim: To verify the gas constant as 8.31 J/mol/K ( ) and to calculate the molar mass of butane. Theory: The ideal gas law‚ PV=nRT‚ is used to model an ideal gas‚ which is a gas with no intermolecular forces other than those of collisions‚ perfectly spherical and elastic particles. Although an ideal gas is a theoretical model and so cannot exist in practice‚ most gases behave fairly similarly to an ideal gas. Gases behave more like an ideal gas when they are at a higher
