Explanation:
I took the test and it was false,
also if it was true then in industrialized countries would be more eco-friendly and there wouldn't be a huge hole in our ozone layer. and no more wars over oil.

<span>Temperature and heat energy are closely related.
</span><span />
<span>While heat is the kinetic energy of the particles of a substance which is transferred from a hotter substance to a cooler one, the temperature is a measure of the average kinetic energy of the particles in a substance.
</span><span />
<span>The relatively high kinetic energy the particles of a warm substance is transferred to the cooler one by the motion (vibration or translation) of the atoms of molecules. The energy transferred is heat energy.</span>
