Changes in state are a great way to understand how heat and temperature work together.
Melting: When ice turns into water, it takes in heat from its surroundings. This heat makes the tiny particles in the ice move faster. As they move faster, the temperature goes up, and the ice changes from solid to liquid.
Freezing: On the other hand, when water turns into ice, it lets out heat to the air. This causes the temperature to drop. As the particles lose energy, they move slower and come together to form a solid.
Evaporation: For evaporation, liquid water takes in heat from the environment. This heat gives some water molecules enough energy to escape and turn into gas. As a result, the temperature of the remaining water goes up.
Condensation: In condensation, water vapor (the gas) gives off heat as it changes back into liquid. This makes the temperature go down.
These processes show us that heat is the energy that moves from one place to another, while temperature measures how much energy the particles have. So, when heat changes happen, we can see changes in temperature as substances switch from one state to another!
