Homework Answers
Assume that the pressure on the balloon will not change throughout
the whole process.
As it is balloon, so number of moles in it should be
constant.
Option (C) and (D) are incorrect.
Room temperature is around (273+25) K
and temperature of liquid nitrogen is 77 K
Therefore, the temperature of balloon will also decrease.
(E) is incorrect.
Aplly the ideal gas equation as follows:
PV=nRT
Here, P, n, R are constant.
Then V = KT
So, with the decrease in the temperature of balloon, it's volume
should also decrease.
(A) is incorrect.
(B) is correct.
