Internal Energy of a gas, ldeal Gas Law 1. The average kinetic energy of a molecule, is called thermal energy, it is directly related to absolute temperature. 1 3 KE (average per molecule) mv(average) =kT (kg =1.38x10-23 J/K) 3KBT 2. The average speed of molecules in a gas: vrms+ т where vrms stands for root-mean-square (rms) speed. 3. The INTERNAL ENERGY of a gas is the TOTAL ENERGY of ALL the N atoms and molecules For a MONATOMIC gas, each...

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?...
What is the total internal energy of 52.7 moles of helium gas at room temperature? _______kj
A cylinder with a movable piston contains 2.00 g of helium, He, at room temperature. More helium was added to the cylinder and the volume was adjusted so that the gas pressure remained the same. How many grams of helium were added to the cylinder if the volume was changed from 2.00 L to 2.90 L ? (The temperature was held constant.) Express your answer with the appropriate units.
