It is found that, when a dilute gas expands quasi-statically from a volume of to a volume of 6.20 L, the gas does 480 J of work. Assuming that the gas temperature remains constant at 330 K, how many moles of the gas’s molecules are contained in the gas?
Two moles of helium gas are placed in a cylindrical container with a movable lid held in place by a piston. The gas is at a temperature of and at a pressure of Pa. The pressure supplied by the piston is decreased but the temperature of the gas does not change. The volume of the gas doubles.
Find the work done by the piston on the gas during the expansion.
How much heat enters the gas? Assume ideal gas behavior.
9.0 moles of a monatomic ideal gas in a cylinder at a temperature of was expanded isothermally from a volume of 4.7 L to a volume of 12.0 L.
What was the change in the gas’s internal energy?
How much work was done on the gas in the process?
How much was the gas heated?
0.50 mol of an ideal gas is quasi-statically compressed at constant temperature. The volume of the gas after compression is 0.20 , where is the initial volume of the gas. Calculate the temperature of the gas if J of work was done to compress it.
1.00 mol of an ideal gas at a pressure of 3.00 atm and a temperature of 300 K expands isothermally to exactly triple its volume. What is the work done by the gas due to its expansion?
When a dilute gas expands quasi-statically from a volume of 0.250 L to a volume of 6.400 L, the gas does 295 J of work. The gas temperature remains constant at 310 K.
How many moles of the gas’s molecules does the gas contain?
What is the change in the internal energy of the gas?
How much is the gas heated?
In an isothermal reversible expansion of an ideal gas at a temperature of , the gas does 25 J of work. What is the entropy change of the gas?
3.0 moles of a monatomic ideal gas in a conducting container with a movable piston is placed in a large thermal heat bath at temperature 420 K and the gas is allowed to come to equilibrium. After the equilibrium is reached, the pressure on the piston is lowered so that the gas expands at constant temperature. The process is continued quasi-statically until the final pressure is exactly of the initial pressure.
Find the change in the internal energy of the gas.
Find the work done by the gas.
How much was the gas heated by the heat bath?
An ideal gas initially at a temperature of and a pressure of 33.4 kPa is compressed isothermally to a pressure of 159 kPa. Calculate the magnitude of work done by 2.00 moles of gas in this process.
An ideal gas expands quasi-statically to twice its original volume. Determine the ratio of the work done in an isothermal expansion to the work done in an isobaric expansion.
