A toy helium balloon is initially at a temperature of T = 20o C. Its initial volume is 0.0042 m3 (It is a 10 cm radius sphere). Assume that the pressure in the balloon always equals atmospheric pressure, 101.3 kPa.

1) The balloon is lying in the sun, which causes the volume to expand by 6%. What is the new temperature,

T = ?

2) By how many Joules did the internal energy of the gas in the balloon increase?

ΔU = ?

3) How much work was done by the gas during the expansion? (It's a positive number.)

Wby =

4) How much heat was added to the gas by the Sun?

Q =
