Question

Which statement explains how heat causes materials to expand?(1 point)
Responses

Higher temperatures increase the kinetic energy of the particles, which causes the particles to move more and take up more space.
Higher temperatures increase the kinetic energy of the particles, which causes the particles to move more and take up more space.

Lower temperatures increase the kinetic energy of the particles, which causes the particles to spread out.
Lower temperatures increase the kinetic energy of the particles, which causes the particles to spread out.

Lower temperatures decrease the kinetic energy of the particles, which causes the particles to move less and take up more space.
Lower temperatures decrease the kinetic energy of the particles, which causes the particles to move less and take up more space.

Higher temperatures increase the kinetic energy of the particles, which causes the particles to pack closely together.

Answer 1

The correct statement that explains how heat causes materials to expand is:

**Higher temperatures increase the kinetic energy of the particles, which causes the particles to move more and take up more space.**

This accurately reflects the principle that as temperature rises, particles gain energy, move more vigorously, and consequently spread apart, leading to expansion.
