Question

In which case would the kinetic energy of particles be increasing?

As the particles are heated, their vibrations and kinetic energy increase.

The kinetic energy of particles increases if metal is heated from room temperature to 200°C.

The kinetic energy of particles increases if metal is cooled from 200°C to 37°C.

The kinetic energy of particles increases if metal is cooled at 1,300°C.

The correct response is:

The kinetic energy of particles increases if metal is heated from room temperature to 200°C.

When particles are heated, they absorb energy, which increases their kinetic energy and causes them to vibrate more vigorously. In contrast, cooling decreases the kinetic energy of the particles.
