Question

When a solid is heated, its atoms vibrate faster and move farther apart. This happens because ______.

पर्याय

• The mass of the atoms increases

• The atoms gain kinetic energy, and the amplitude of vibration increases

• New atoms are added to the solid

• The atoms stop vibrating and drift apart

Answer 1

When a solid is heated, its atoms vibrate faster and move farther apart. This happens because the atoms gain kinetic energy, and the amplitude of vibration increases.

Explanation:

The atoms gain kinetic energy and the amplitude of vibration increases
