Question

How much energy in kJ is needed to raise the 12 kg of now gaseous nitrogen N, from boiling temperature, -196 °C, to room
temperature, 20°C.? The specific heat of nitrogen gas is is c = 1,004 Joules/kg°C.

Expert Solution

Step 1

Scenario - Nitrogen gas is heated further from its boiling temperature to bring it to room temperature.

Given :

Nitrogen mass $\to m = 12 k g$

Boiling temperature $\to T_{1} = - 196 ° C$

Room temperature $\to T_{2} = 20 ° C$

Nitrogen specific heat $\to c = 1004 J / k g ° C$
