Which statement explains how heat causes materials to expand?
Higher temperatures increase the kinetic energy of the particles, which causes the particles to pack closely together.
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 move more and take up more space.
Lower temperatures increase the kinetic energy of the particles, which causes the particles to spread out.
