============================================
Explanation:
Q = heat transferred
m = mass
c = specific heat

Solids and liquids have volumes thatdo not change easily. A gas, on the other hand, has a vol- ume thatchanges to match the volume of its container. The molecules in a gas are very far apart compared with the molecules in a solid or a liquid. The amount of space between the molecules in a gas can change easily.
Enthalpy change refers to the overall amount of heat added or lost with each step as you progress through your reaction.
