A helium-filled toy balloon has a gauge pressure of 0.250 atm and a volume of 8.0 liters. How much greater is the internal energy (in J) of the helium in the balloon than it would be at zero gauge pressure?

A chemical reaction transfers 8150 J of thermal energy into 11.4 moles of an ideal gas while the system expands by 2.00 x 10-2 m³ at a constant pressure of 1.63 × 105 Pa. HINT (a) Find the change in the internal energy (in J). J (b) Calculate the change in temperature of the gas (in K). K

Suppose a tank contains 636 m³ of neon (Ne) at an absolute pressure of 1.01x105 Pa. The temperature is changed from 293.2 to 295.0 K. What is the increase in the internal energy of the neon? ΔU = i

A cylinder with a piston holds 4.50 moles of a monatomic gas. The gas in the cylinder absorbs 935 J of energy due to the higher temperature of the environment. At the same time, the cylinder expands to a larger volume, doing 152 J of work on the environment. (a) What is the change in internal energy of the gas in the cylinder (in J)? (b) What is the change in temperature of the gas (in K)?

A typical helium balloon contains 1.1 g of helium gas.At 18∘C room temperature, what is the total kinetic energy of the helium in the balloon?

Upon kicking a ball ( d = 22 m ) you noticed that it compressed to 90% of its original volume. If a regulation soccer ball has an average gauge pressure 12.05 psi. what is the internal energy change (J) experienced by the air inside the ball?

The volume of an ideal gas is increased from 1 m3 to 3 m3 at a constant pressure of 1000 Pa          How much work is done by the gas in the expansion?                          W= _________ J          If no heat has been added or removed, what is the change in internal energy of the gas?           DU = ________ J

What is the total internal energy of 2.00 moles of an ideal gas at 100 K?

A car tire contains 0.0390 m3 of air at a pressure of 2.20×105 N/m2 (about 32 psi). How much more internal energy does this gas have than the same volume has at zero gauge pressure (which is equivalent to normal atmospheric pressure)?

A sample of a monoatomic ideal gas has a pressure of p and volume V. When the gas is warmed, it’s pressure triples and volume triples. This warming process includes two steps, the first at constant pressure and the second at constant volume. Determine the amount of energy transferred to the gas by heat.
