Question

which refers to the amount of heat required to change the temperature of 1 gram of a substance by 1°c and is related to the chemical composition of the substance?
thermal energy
specific heat
activation heat
boiling point

Explanation:

Specific heat is defined as the amount of heat needed to change the temperature of 1 - gram of a substance by 1°C and it depends on the chemical composition of the substance. Thermal energy is the total kinetic energy of the particles in a substance. Activation heat is related to the energy needed to start a chemical reaction. Boiling point is the temperature at which a substance changes from liquid to gas.

Answer:

Specific heat
