24. Suppose that an ideal gas is inside a container with a movable piston. Which of the following statements is true? 1) Increasing the temperature of the system while keeping the volume constant causes the gas to perform work. 2) When work is done by the system on the surroundings while temperature is kept constant, the pressure of the gas increases. 3) If temperature is kept constant, then decreasing the pressure of the gas causes a increase in volume 4)...
which compresses the gas to a smaller volume as seen in the figure. What is the final pressure of the helium gas?
5. A cylinder with a movable piston contains 0.41 mole of helium gas. The piston is open to the atmosphere on the top and has a mass of 30 kg and a radius of 0.1 m. The gas and cylinder are in equilibrium with the atmosphere, which has a temperature of 290 K and pressure of 1.00 x 10s Pa. The initial volume of the helium inside the cylinder is 0.0090 m when a 60-kg mass is placed on top...

A sample of gas in a 35.0 L cylinder-piston assembly has a pressure of 1.55 atm at 125oC. If the pressure on the gas increases to 3.0 atm while the volume of the gas decreases to 25.0 L, what is the temperature (oC) of the gas?
Which of the following statements about the relationship between pressure and temperature is true? Increasing the...
Which of the following statements about the relationship between pressure and temperature is true? Increasing the temperature would make some of the gas escape from the balloon, decreasing the volume. As temperature increases, the volume of a gas decreases. As temperature increases, the volume of a gas also increases. The volume of a gas is affected by temperature changes, but it is not possible to predict how it is affected The volume of a gas is unaffected by temperature changes.

Review Constants Periodic Table Air consists mostly of nitrogen (N), with a molecular mass of 28, and oxygen (O2), with a molecular mass of 32. A water molecule (H,O) has molecular mass 18. According to the ideal gas law (N/ V P /KT), dry air at a particular pressure and temperature has the same particle density (number of particles per unit volume) as humidait at the same pressure and temperature. Consequently, humidair, whose low-mass water molecules replace more massive nitrogen...
