What is the effect of increasing temperature on physisorption?
Correct Answer: Increasing temperature decreases physisorption.
- Step 1: Understand what physisorption is. It is the process where molecules stick to a surface through weak forces called van der Waals forces.
- Step 2: Know that temperature is a measure of how much energy the molecules have. Higher temperature means more energy.
- Step 3: Realize that when temperature increases, the energy of the molecules also increases.
- Step 4: Understand that the increased energy can cause the molecules to move more vigorously.
- Step 5: Recognize that the weak van der Waals forces that hold the molecules to the surface can be disrupted by this increased movement.
- Step 6: Conclude that as temperature increases, the physisorption decreases because the molecules are less likely to stay attached to the surface.
