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?

In this case, the specific heat capacity of oxygen is 918 J/kg °C. That means that it takes 918 J of energy to raise 1 kg of oxygen by 1°C.

Explanation:

Specific heat is the amount of heat required to raise the temperature of a unit mass of a substance by one degree. Specific heat is also known as specific heat capacity or specific heat capacity.

In other words, it is defined as the amount of energy that we must contribute to increase its temperature.

The specific heat or heat capacity of a certain body is called by the letter "c".

The expression to calculate the specific heat of a substance is:

c = Q / m.Δt

where Q represents the heat energy transfer between the system and its environment, m the mass of the system and Δt the temperature variation to which it is subjected.

In this case, the specific heat capacity of oxygen is 918 J/kg °C. That means that it takes 918 J of energy to raise 1 kg of oxygen by 1°C.
