Question

Name two quantities that are not regarded as matter.

Answer 1

light is not regarded as matter

Answer 2

Explanation:

Heat and light are not regarded as matter. This is because heat and energy both do not have any mass and do not occupy any space. For anything to qualify as matter, it has to have some mass and occupy some space.

Heat and light are in fact forms of energy. Energy is the ability to do work. Matter may possess energy but energy in any form is not matter. Heat and light can be observed but these cannot be put on any kind of weighing scale to be measured.
