Question

The specific heat capacity of oxygen is 918 J/kg °C. That means that it takes 918 J of energy to raise _____ kg of oxygen by 1°C. What number completes the sentence?

Answer 1

Answer:

1 is the answer.

Hope it will help you!!

Answer 2

Answer:

Water

Explanation:

1. Given the specific heat of oxygen is 918J/kg °C and the specific heat of water is 4181 J/kg °C.
3. Consider 1Kg mass of each substance.
5. Now 1 Kg of oxygen needs 918 J of energy to raise its temperature by 1 °C
7. Also, 1 Kg of water needs 4181 J of energy to raise its temperature by 1 °C.
9. Clearly water requires more energy when compared to oxygen.
11. Basically, specific heat capacity is the amount of energy required to raise the temperature of a 1 kg body by 1 °C
