Question

The specitic heat capacity of oxygen is 918 J/kg °C. The specific heat capacity of water is 4181 J/kg °C. Which substance will require more energy to raise its temperature by 1°C?​

Answer 1

Water

Step-by-step explanation:

Given the specific heat of oxygen is 918J/kg °C and the specific heat of water is 4181 J/kg °C.

Consider 1Kg mass of each substance.

Now 1 Kg of oxygen needs 918 J of energy to raise its temperature by 1 °C

Also, 1 Kg of water needs 4181 J of energy to raise its temperature by 1 °C.

Clearly water requires more energy when compared to oxygen.

Basically, specific heat capacity is the amount of energy required to raise the temperature of a 1 kg body by 1 °C.
