Diffusion and Osmosis Worksheet Diffusion is the movement of particles from areas of higher concentration to areas of lower concentration. It is a natural‚ random process. This means that it does not require extra energy input. 1a. These are pictures of molecules frozen at two different times. Draw arrows to show the direction each particle might travel due to diffusion in diagrams A and B. A. B. Random arrows Random arrows 1b. Describe the way the particles

Gas Laws Name Institution The 3 Gas Laws Introduction The three gas laws include: Gay-Lussac’s law‚ Boyle’s law and Charles’ law. When combined with Avogadro’s law the three laws can be generalized by the ideal gas law. Gases possess observable properties which include‚ mass‚ pressure (P)‚ thermodynamic temperature (T) and volume (V). These properties are related to each other and the state of a gas is determined by their values. The three laws are derived from these properties. Discussion

COEFFICIENT OF RESTITUTION The coefficient of restitution (e or COR) is defined as a number that serves as an index of elasticity for colliding bodies (Hall‚ 2012). Essentially‚ it measures the rebound of a ball after a collision with another object‚ like a golf club striking a stationary golf ball. A perfectly elastic ball will have a COR of 1‚ and a perfectly plastic ball will have a COR of 0. In golf‚ the coefficient of restitution comes into play when the club head impacts the ball‚ and

Throughout this lab‚ diffusion and osmosis has been seen and tested through experiment. In part A of the lab‚ diffusion was demonstrated with two solids and an agar gel petri dish. One crystal of potassium permanganate and one crystal of methylene blue were placed on either side of an agar gel petri dish. The purpose of this experiment was to determine which of the crystals would diffuse across the gel more. So the question is‚ which solid would have a higher rate of diffusion through the agar‚ methylene

DIFFUSION REVIEW WORKSHEET 1. Define diffusion and what causes it to occur? The action of spreading the light from a light source evenly so as to reduce glare and harsh shadows. Diffusion is caused when entities are small and moving in molecules. They collide because they are moving at a random pace. The temperature causes diffusion. 2. Define the terms hypertonic‚ hypotonic‚ and isotonic solution. * Hypertonic: Having increased pressure or tone‚ in particular. * Hypotonic:

Gas analysis techniques Terms for gas analysis techniques Concentration The term concentration describes the amount of a substance‚ expressed as mass‚ volume‚ or number of particles in a unit volume of a solid‚ liquid‚ or gaseous substance e.g. alcohol in beer or oxygen in air. Different units are in use to describe concentration in gases: Mass concentration Concentration expressed in terms of mass of substance per unit volume [g substance/m3 gas volume] ¢ Volume concentration Concentration

Diffusion in Cells Isabel Zak Question: How does the size of a cell affect the distribution of chemicals throughout the cell? Hypothesis: The larger the cell is‚ the more difficult it will be for the chemicals to reach the centre of the cell‚ and diffuse throughout it. This is because there will be a higher surface-area to volume ratio in the larger cells‚ making the centre of the cells further away from the surface. Therefore‚ when dipped in sodium hydroxide‚ the larger cells will not
