Hydrogen gas is enclosed in a chamber at 200 degrees C and a volume of 0.0250 m3. Initially, the pressure in the gas is 1.50 x 106 Pa. The chamber is removed from the heat source and allowed to cool until the pressure in the gas falls to 0.950 x 106 Pa. What is T2?

A cylinder with a diameter of 5.64 cm has a movable piston attached to a spring as shown in Figure P.40. The cylinder contains 1.32 liters of an ideal gas at 17.8°C and 0.93 atm pressure. After the gas is heated briefly and allowed to expand, it is found that the spring compresses 3.42 cm and the temperature of the gas increases to 103°C. What is the change in volume for this expansion?_______ mLWhat is the change in pressure?_______ atmWhat is the spring constant k?_______ N/m

For many purposes we can treat propane (C3H8) as an ideal gas at temperatures above its boiling point of −42.°C. Suppose the temperature of a sample of propane gas is lowered from 60.0°C to 10.0°C, and at the same time the pressure is increased by 15.0%.     Does the volume of the sample increase, decrease, or stay the same?   increase decrease stays the same           If you said the volume increases or decreases, calculate the percentage change in the volume. Round your answer to the nearest percent.     %

4.0 moles of krypton gas are in a 0.20m3 container. The pressure is 1.663 x 105 Pa.  a, What is the temperature (to the nearest K)? The volume contracts to 0.10m3. The pressure is held constant.  b, How much work was done by the gas during the volume contraction?  c, What is the temperature after the volume contraction (to the nearest K)?
