The amount of heat lost by the air in the football and the gauge pressure of air in the football at the stadium respectively equal
-
- 30.6 J, 1.94 bar
- 21.8 J, 0.93 bar
- 61.1 J, 1.94 bar
- 43.7 J, 0.93 bar
Correct Option: A
P1V1 = mRT1
m = 6.049 × 10–3kg
Q = mCv dT
Q = –43.43J
P2V1 = mRT2
P2 = 1.93 bar (absolute)
P2 = 1 – 1.93
P2 = 0.93 bar
