Question

the change in energy is a measure of​

Answer 1

Answer:

When this transfer of energy creates temperature changes, we call this transfer “heat.” Since heat can be defined in terms of temperature changes, this tells us that temperature and heat are very closely related concepts. We need a means to measure temperature.

Answer 2

Explanation:

To calculate an energy change for a reaction:

add together the bond energies for all the bonds in the reactants - this is the 'energy in'

add together the bond energies for all the bonds in the products - this is the 'energy out'

energy change = energy in - energy out.
