Question

If the temperature of a substance is increased, what will be the effect on its density?

Answer 1

1. The mass of an object does not vary with the temperature and remains constant.
2. The volume of an object varies directly with the temperature.
3. We know, density(D) = Mass( M)/ Volume (V)
4. Thus, density varies inversely with the volume of any object.
5. Hence, the density of an object decreases with an increase in its volume due to a rise in the temperature of the object and vice versa.
