How does the rate of reaction change with temperature and why?
Rate of reaction increases with temperature - As we increase the temperature, reactants particles move faster, which increases the probability of successful collisions, which means an increased rate of reaction.
What are the main differences between plant cells and animal cells?

Explain why the evaporation of water from our skin causes us to feel colder?
Evaporation is described as the process of the state change of a liquid below its boiling point. The water molecules on the skin absorb the energy from the skin and change their state to gaseous form, leaving the skin with less energy. The loss of heat through the evaporation of water makes the area feel colder.
