Front

How does increasing pressure affect the rate of a chemical reaction?

Back

Elevating the pressure of the reaction increases the reaction rate by increasing the frequency of collisions.

Front

What happens to heat energy when it is transferred to a pot and then to the liquid inside?

Back

Heat energy is transferred to the spoon and air.
