detailed answers ||
What is heat? - ✔✔Energy transefrred between bjects due to a change if temperature.
|| || || || || || || || || || || || ||
What is temperature? - ✔✔A measure of the internal energy of a substance, not equal to
|| || || || || || || || || || || || || || || ||
heat.
What is internal energy? - ✔✔Amount of energy in an object due ti the internal motion of
|| || || || || || || || || || || || || || || || ||
the atoms and mass.
|| || ||
