Question

What happens to the density of a fluid as the substance gains thernal energy

Answer 1

Density reduces

Explanation:

The density of a fluid will reduce as a substance gains more thermal energy. Heat is a form of thermal energy usually noticed as temperature differences in a matter.

• When thermal energy is gained by a body, the temperature of the body rises.
• The particles of the medium gains more kinetic energy.
• This causes the substance to expand and it has more volume.
• When a substance expands, it occupies more space.
• The more the volume a body occupies, the lesser the density.
• Expansion does not change the mass of the fluid but the volume changes.
• This is why density decreases.
