A helium-filled balloon has a volume of 0.010 m3. The temperature in the room and in the balloon is 20oC
a. Obtain the average kinetic energy of a particle of helium inside the balloon?
b. Obtain the average speed of a particle of helium inside the balloon?
c. Obtain the thermal energy of the helium in the balloon? Suppose that due to stretching of the balloon the pressure inside it is 1.1 atm.
