Factors Affecting Diffusion
How does temperature affect diffusion?
What is Diffusion?
Definition 1:
Diffusion is a process where by molecules move from an area of high concentration area to an area of low concentration.
Definition 2:
Diffusion is an evidence for moving particles. The spreading out of a gas is called diffusion and it takes place in haphazard and random way. Gases diffuse because the particles collide with other particles and bounce of in all directions.
For example when you smell food it is been diffused with the air because the air has particles of a high concentrated area and the food has molecules of a lower concentrated area therefore these to mix and create diffusion.
Factors affecting diffusion:
There are two main factors which affect diffusion:
Temperature: the higher the temperature the faster the rate of diffusion, as there is more kinetic energy.
Mass of particles: the lower the mass or relative molecular mass the faster the rate of diffusion.
Out of these two factors, I have decided to investigate how temperature affects diffusion
Title: How does temperature affect diffusion Aim: To take 6 beakers with water at different temperatures and add food colouring and observe which diffuses the fastest
Hypothesis: I think the beaker with the hottest water will diffuse the fastest because the higher the temperature the faster the rate of diffusion, since there is more kinetic energy being added to the molecules. Variables-
Independent- temperature of water in a beaker
Dependant – time taken to diffuse
Control- Amount of Food Colouring and amount of water
Apparatus- water (room temperature), 5 beakers, stopwatch, food colouring, Tile, Safety goggles, Bunsen burner, Tongs, Ice, and Thermometer, Tripod stand, cold water, Tile, Dropper, Gauze.

Method:
Take ice and put it in a beaker. Add some water 200ml. Make sure that the beaker is at exactly 10 degrees Celsius. Get your stopwatch ready. Next add a measured

    Factors Affecting Photosynthesis Low light intensity lowers the rate of photosynthesis. As the intensity is increased the rate also increases. However, after reaching an intensity of 10,000 lux (lux is the unit for measuring light intensity) there is no effect on the rate. Very high intensity may, in fact, slow down the rate as it bleaches the chlorophyll. Normal sunlight (usually with an intensity of about 100,000 lux) is quite sufficient for a normal rate of photosynthesis. Open and Closed…

    Factors Affecting Climate: Latitude: The further a place is from the Equator the lower the temperature becomes Distance from the Sea: Continental Effect-places in the middle of a large landmass, or a long way from the coast will have a greater variation (difference) in temperature than places close to the coast, because land heats and cools quicker than water. The impact on climate of being close to the coast is the Maritime Effect. Elevation: Altitude = height above sea level. The higher up the…

    price is low and less of it when the price is high. In other words, price and quantity demanded move in opposite direction, if price goes up, demand goes down. And if price goes down, demand goes up. Factors affecting the demand for a good: * Price: The price of the good itself is the first factor that affects the demand for a good. For goods that obey the law of demand, if the price rises the quantity demanded falls and if the price falls the quantity demanded rises. But for goods that do not…
