Topic 1 Specific Heat Capacity

Question 1

What is specific heat capacity

Answer 1

The amount of energy required to raise the temperature 1 kg of material by 1°

Question 2

What does it mean if a material Can store a lot of energy

Answer 2

They need to get lots of energy in the thermal energy store to warm up and also transfer loads of energy when they cool down again

Question 3

Specific heat capacity equation

Answer 3

∆E = mc ∆θ

∆E= change in thermal energy (j). M= mass (kg). C= specific heat capacity (j/kg’c). ∆θ= change in temp (‘c)
