Heat and temperature are really important for understanding how things change from one state to another. Like when water turns into ice or steam.

Let’s break it down:

1. Heat: This is the energy that moves from one object to another because they are at different temperatures. For example, when you heat ice, you make it warmer. This added energy makes the ice molecules move around faster.

2. Temperature: This tells us how hot or cold something is. It's a way to measure how quickly the tiny particles in a substance are moving. Higher temperatures mean the particles have more energy and are moving really fast.

When you give enough heat to a solid, like ice, it eventually reaches a point called the melting point. At this point, it turns into liquid water.

If you keep heating the water, it will boil and change into steam.

So, to put it simply:

• Heat is the energy that helps things change.
• Temperature tells us how much energy the particles have and helps us know when these changes will happen.

That's how we see phase changes in everyday life!
