You accidentally release a helium-filled balloon that rises in the atmosphere. As it rises, the temperature of the helium inside decreases from 20C to 10C.
the average speed of helium atoms in the balloon will decrease
the average speeds between the initial and final states--> 0.98
he thermal energy of the helium inside the balloon will decrease
Determine the ratio of the thermal energies between the initial and final states?
Homework Answers
The ratio will be 0.9658 as the thermal energy is directly proportional to the temperature. Hence ratio will be T2/T1 in Kelvin. Or u can say that ratio of energies will be square of ratio of average speeds.

Fun with a helium balloon A loosely filled balloon contains 4.5 liters of helium gas at atmospheric pressure (PA = 101 kPa) and room temperature T = 20 C. The gas in the balloon is then heated to body temperature, 37 C, by a student. (a) The pressure inside the balloon changes very little during the heating process. What is the change in the volume of the balloon? (b) How much work does the expanding balloon do on its environment?...
