Question

A 1.00 mole sample of N2 gas at 0 ∘C is heated to 180 ∘C at constant pressure (1.00 atm).

1. Determine the change in internal energy.

2. Determine the work the gas does

3. Determine the heat added to it.

Answer 1

Answer #1

A)

Change in internal energy, dU = n(5/2)R dT

dU = 1 x (5/2) x 8.314 x 180 = 3741.3 J

B)

Work done, W = nRdT = 1 x 8.314 x 180 = 1496.52 J

C)

Heat, Q = dU + W = 5237.82 J

The amount of heat needed to raise the temperature of 1 mole of a substance by one Celsius degree (or, equivalently, one kelvin) is called the molar heat capacity of the system, denoted by the letter C. If a small amount of heat dQ is put into n moles of a substance, and the resulting change in temperature for the system is dT, then C=1ndQdT. This is the definition of molar heat capacity--the amount of heat Q added per infinitesimal...
