Specific heat capacity

Question 1

What is Specific heat capacity?

Answer 1

• Amount of energy required to raise temperature of 1kg of the substance by 1*C

Question 2

Formula for energy change that occurs when object changes temperature:

Answer 2

Energy transferred = mass X specific heat capacity X temperature change
/\E (J) = m (kg) X c (J/kgC) X /\ϑ (C)

Question 3

How does the mass of a substance affect how quickly its temperature changes when it’s heated?

Answer 3

• The greater the mass the slower the temperature rises when heated

Question 4

Formula for Specific heat capacity:

Answer 4

• Rearrange energy change
  Specific heat capacity = energy transferred / mass X temperature change
  c (J/kgC) = /\E (J) / m (kg) X /\ϑ (C)
