Problem 4: Isothermal expansion The container has the shape of cylinder with the radius of circle 1 m and the length 2m. It is filled with 20 moles of the gas and kept at the pressure 10kPa. We add the heat of 3 k.J to the gas and it undergoes an isothermal expansion (one wall is movable) a) What is the temperature of the gas in °C in the container before the expansion? [6pt b) What is the change of...

A 0.4 mol of a monatomic gas (dof = 3) is held inside a cylinder and piston as shown below. The gas is initial at a temperature of 293K. The air outside the piston and cylinder exerts an average force of 1313N. A flame is held to the cylinder and heat is added to the gas. The piston slides to the left a distance 0.08 m as 175 Joules of heat is added to the gas. What is the final...

1) A cylinder is filled with 0.10 mol of an ideal gas at
standard temperature and pressure, and a 1.4-kg piston seals the
gas in the cylinder (see figure) with a frictionless seal. The
trapped column of gas is 2.1-m high. The piston and cylinder are
surrounded by air, also at standard temperature and pressure. The
piston is released from rest and starts to fall. The motion of the
piston ceases after the oscillations stop with the piston and the...

Part A: A gas cylinder has a volume of 43.20 litres. If the cylinder contains helium at a temperature of 28.00 deg. C and an absolute pressure of 1800 psi, how many moles (mol) of gas are contained in the cylinder? Part B: If the temperature of the gas is increased to 78.0 deg. C, what will the absolute pressure be?

A gas is contained in a vertical, frictionless piston-cylinder device. The piston has a mass of 3.2 kg and a cross-sectional area of 35 cm2. A compressed spring above the piston exerts a force of 110 N on the piston. If the atmospheric pressure is 95 kPa, determine the pressure inside the cylinder. The pressure inside the cylinder is _______ kPa.

1. The drawing shows an ideal gas confined to a cylinder by a
massless piston that is attached to an ideal spring. Outside the
cylinder is a vacuum. The cross-sectional area of the piston is A =
2.50 × 10-3 m2. The initial pressure, volume, and temperature of
the gas are, respectively, P0, V0 = 6.00 × 10-4 m3 and T0 = 273 K,
and the spring is initially stretched by an amount x0 = 0.092 m
with respect to...
