A balloon contains Helium (a monatomic ideal gas) at a pressure of 101325Pa and temperature of 20.0◦C. Please note that the pressure inside of a balloon must always equal the atmospheric pressure outside of the balloon.

(a) If the volume of the balloon is 0.015m3, how many moles of Helium are inside the balloon?

(b) What is the rms speed of the Helium in the balloon? (The molar mass g
of Helium is 4.002602mol.)

(c) If the temperature of the system is increased to 25.0◦C what is the new volume of the balloon?

(d) How much heat was added to increase the temperature from 10◦C to 25◦C?

(e) What is the change in the entropy of the gas inside of the balloon?
