Question 23
The specific heat capacity (SHC) of a material is defined as the amount of energy required to raise the temperature of 1 kg of the material by 1°C. When 1000 J of thermal energy is transferred to 200 g of material X the temperature increases by 4 °C. When 2000 J of thermal energy is transferred to 100 g of material Y the temperature increases by 8 °C. The ratio of their specific heat capacities, SHC of X : SHC of Y is:
