P1.2.3 - Specific heat capacity

Question 1

What does the amount of energy need to raise the temperature if an object depend on?

Answer 1

• the type of material
• the mass of the material
• the temperature rise

Question 2

What is the specific heat capacity of a material?

Answer 2

The energy needed to raise the temperature of 1kg of a material by 1K is its specific cheat capacity

Question 3

How do you calculate specific heat capacity?

Answer 3

Change in thermal energy = mass x specific heat capacity x change in temperature

Question 4

What can tell specific heat capacity tell you?

Answer 4

It tells you how resistant a material is to a change in temperature

Question 5

Why are saucepans made of materials with low specific heat capacity?

Answer 5

Because they need to heat up quickly
