What is the approximate energy required to heat 3 liters of air at standard temperature and pressure by 125 $\circ$ C? The volume is held constant.

Question

Quizplus · Accepted Answer

The specific heat capacity of air at constant volume is 0.718 J/g°C. 
3 liters of air at standard temperature and pressure has a mass of approximately 3.81 grams. 
To raise the temperature by 125°F, which is equivalent to 69.44°C, the energy required would be:
E = m * C * ΔT
E = 3.81 g * 0.718 J/g°C * 69.44°C
E ≈ 345 J. 
Therefore, the best choice is (D) 345 J.
