Hello dear,

● Answer-
∆E = 17.2×10^6 J

● Explanation-
# Given-
W = 1000 kg
∆T = 60° C = 60 K

# Solution-
As standard convention, molar mass of air is taken as 0.029 kg/mol.

No of moles of air in balloon-
n = 1000 / 0.029
n = 34483

Change in thermal energy of air is calculated by-
∆E = nR∆T
∆E = 34482 × 8.314 × 60
∆E = 17.2×10^6 J

Therefore, change in thermal energy of air is 17.2×10^6 J.

Hope this helps...
