What would happen in each of the following diffusion situation? In each situation a 1cm³ volume of salt is placed into 50 mL of tap water at 20℃.
a. The water is heated to 40°C
b. The water has two teaspoons of salt already dissolved in it before the salt is added
Answers
Explanation:
a. As the water is heated to 40°C it increase the rate of diffusion, therefore the salt diffuses faster into the water.
b. The rate of diffusion decreases as the solution becomes saturated; leaving undissolved salt particles on the bottom of the container.
a. When water is heated to 40°C, the speed of diffusion increases, allowing the salt to diffuse quicker into the water.
b. Once a solution gets saturated, the rate of diffusion slows, leaving undissolved salt particles at the bottom of the container.
Higher temperatures enhance the energy of the molecules, which causes them to travel faster, increasing the rate of diffusion. Lower temperatures reduce the energy of the molecules, slowing the diffusion rate.
Simple diffusion is not saturable; however, assisted diffusion rates are constrained by the amount of functioning membrane proteins and can reach saturation. Diffusion is defined as the net movement of particles (molecules) from a high-concentration area to a low-concentration area.
