Question

When fluids are heated, the molecules closer to the source get heated and expand.

• A. True
• B. False

Answer 1

The correct option is A True

1. The property of the substance due to which it expands on heating is called thermal expansion.
2. The expansion of fluids also depends upon temperature. If we increase the temperature of fluids, the internal energy of the molecules increases, and so is the inter-molecular distance between the molecule.
3. Due to the increase in the inter-molecular distance between the molecules of fluids, the fluids expand.
   Hence, the given statement is true.
