Physical Science

Remember!

The temperature change in a substance depends on:

• how much heat energy is transferred to the object
• the mass of an object

• what the object is made of.

Let’s Understand

Look at the picture below and discuss what is happening in terms of heat
energy and temperature.

Now watch the demonstration.

Use the worksheet in the Workbook to record the results, and explain what
happened and why.

Let’s Reflect

1 What three things can change how much heat energy a substance has?

2 What does temperature measure?
