A container holds 0.70 g of oxygen at a pressure of 8.3 atm .
a. How much heat is required to increase the temperature by 119 ∘C at constant pressure?
b.How much will the temperature increase if this amount of heat energy is transferred to the gas at constant volume?
number of moles
n = given mass / molar mass = 0.7 / 32
n = 0.022 moles
enervy needed for diatomic gas
q = (7/2) n R (T2 - T1)
q = 3.5* 0.022* 8.314* 119
q = 75.748

b)
for constant volume diatomic gas
q = (5/2) nR (T2 - T1)
75.748 = 2.5* 0.022* 8.314* dT
dT = 165.65 C
