goal‚ cutting the straw caused the gases to not have to go as far‚ and meet in the middle. Background The particles in a gas are very loose and tend to move around a lot very quickly. The particles in a solid are very compact and vibrate but don’t really move very much. The particles in a liquid however are more lose than the particles in a solid but not less than a gas.

MIXTURES‚ SOLUTIONS‚ SUSPENSIONS AND COLLOIDS MIXTURES A mixture is a combination made up of two or more different substances which are mixed but are not chemically bonded. There are also types of mixtures such as homogeneous mixtures and heterogeneous mixtures. SOLUTIONS A solution is defined as a homogeneous mixture composed of a solute; a substance dissolved into another substance known as a solvent. They can also be defined as groups of molecules that are mixed up completely in even

Dry ice is a solid which is known as the solid format of carbon dioxide which is an odorless gas made by burning carbon henceforth the name .Carbon dioxide is what humans exhale and pants inhale. Dry ice is a very popular experimentation factor this is because of the name which come from the fact that dry ice doesn’t melt. The differences among standard frozen water ice is that the standard ice melts while dry ice on the other hand does not. Dry ice also maintains a very vibrant white color compared

of the substance under consideration without distinguishing whether a substance is an element ‚ a molecule or an ionic compound. These elements‚ molecules or ionic compound could be solid gas or liquid. The molar mass of gas or vapor could be measured if the gases obey the law of Ideal Gas . The mass of the gas is found under known temperature and pressure. Method/procedure To measure the unknown volatile liquid molar mass‚ the formal to be used is PV=nRT‚ n=PV/RT and MM=g/n The step helps

phase state to another‚ or in other words‚ when it goes from either a solid to liquid or liquid to gas. The potential energy that is stored between molecules of the substance needs to be overcome by the kinetic energy of the motion of the particles before the substance can undergo the phase change. The temperature of a substance as heat is added to change the phase from the solid state to the gas state is shown below. Phase changes are indicated by flat regions where heat energy is used to overcome

variable is the amount (in mL) of CO2 gas produced by the yeast. The biotic factor in this experiment is what effect the concentration of the yeast has on its ability or inability to reproduce efficiently. The lab tests three different concentrations of the yeast: add 0.25 mL‚ 0.5 mL‚ or 1 mL of yeast suspension to the test tube. The independent variable is the amount of yeast concentration added and the dependent variable is the amount (in mL) of CO2 gas produced by the yeast. INTRODUCTION Yeast
