Final answer:
The statement that a change in temperature can cause changes in the phase of matter is true. These phase transitions occur at specific temperatures, known as the melting point and boiling point, and involve the absorption or release of latent heat.
Step-by-step explanation:
A change in temperature can cause changes in the phase of matter. The statement is true. Substances can indeed change phase due to temperature change. For instance, at low temperatures, most substances are solid. With an increase in temperature, they may melt into a liquid, and upon further heating, evaporate into a gas. These transformations are related to the concepts of melting point and boiling point, which are the specific temperatures at which substances transition between solid and liquid, or liquid and gas, respectively. During phase changes like these, latent heat is absorbed or released, causing the phase change without altering the temperature of the system.
Latent heat is the energy transferred to or from a substance, resulting in a phase change without a temperature shift in the substance itself. The type of phase change—from solid to liquid, liquid to gas, and vice versa—depends on whether heat is being added or removed from the substance.
