A balloon filled with 39.1moles of He has a volume of 876L at a0.0°C and 1.00atm. The temperature of the balloon is increased to 38.0°C as it expands to a volume of 998L, while the pressure remains constant. Determine q, w, and ΔE for the He in the balloon. The molar heat capacity of He is 20.8 J/mol·°C.

ANSWER- Here we have given
n=39.1 moles of He
c is the specific heat capacity= 20.8 J/mol.  C
T2 = 38.0  C
T1 = 0.0  C
  T is the temperature change
V2 = 998 L
V1 = 876 L

P = 1.00atm
