A rigid container holds 4.00 mol of a monatomic ideal gas that has temperature 300 K. The initial pressure of the gas is 6.00 * 104 Pa. What is the pressure after 6000 J of heat energy is added to the gas?
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...
The temperature of 3.5 mol of a monatomic ideal gas is 320 K. The internal energy of this gas is doubled by the addition of heat. (a) How much heat is needed when it is added at constant volume? (b) How much heat is needed when it is added at constant pressure?
A container holds 4.5 mol of an ideal monatomic gas with a pressure of 125 kPa. The container initially has a volume of 0.10 m3. The gas undergoes an adiabatic expansion until it reaches a volume of 0.3 m3 and a pressure of 20.0 kPa. What is the thermal energy of the gas after the expansion? How much energy went into or out of the gas as work during the expansion? (Positive for energy into the gas, negative for energy...
