2.00 mol of helium is heated in a rigid container (constant volume). If 80.0 J are added to the container, what is the change in temperature of the gas?
A weight is added to a piston so that the volume of the gas inside the container is reduced from 3.0 L to 1.0 L at a constant temperature. How much heat do you need to add to the system if you want to increase the volume back to 3.0 L at this new pressure? Assume an ideal gas and an initial pressure of 1.0 atm
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?
Ten moles of a gas are placed in a rigid container. Initially the gas is at P=0.5 bar and T= 300 K and the container is also at T= 300K. The container is placed in a furnace, where its surroundings are at a constant T = 600K. The container is left in the furnace until both the container and the gas inside it reach equilibrium with the surroundings. The gas has a constant heat capacity of Cv = 2.5 R....
A sample of 1.3 mol of CO2 (g) is placed in a 5.0 L rigid container at an initial temperature is 300 K. When 6.98 kJ of heat is added to the system (at constant volume), the temperature rises to 353 K. Calculate q, w, ∆U, ∆H, and CV. The molar heat capacity of O2(g) at constant pressure, is 31.2 J/(K mol) around room temperature. 2.5 mol of O2(g) is heated at constant pressure from 265 K to 310 K....
A gas sample is initially at 40.3 atm and 7.68 L. If the pressure is adjusted to 7.28 atm, what is the new volume of the gas sample? (Assume the sample is maintained in a closed container with constant temperature). Enter an integer or decimal number, with exactly 3 significant figures (more. Show your work: A latex balloon will adjust to maintain the same pressure. If the balloon is filled with 14.8 L of helium initially at 17.5 degrees Celcius,...
A flexible container at an initial volume of 6.13 L contains 4.51 mol of gas. More gas is then added to the container until it reaches a final volume of 16.7 L. Assuming the pressure and temperature of the gas remain constant, calculate the number of moles of gas added to the container. number of moles of gas: _______ mol
Dinitrogen pentoxide is added to an evacuated rigid container at 25 degrees Celsius. Given that the initial pressure is 1.00 atm and at equilibrium the pressure is 0.500 atm, determine the final pressure in the reaction vessel at equilibrium.
