Question

In the initial state, an ideal gas has pressure p1, volume V1
and temperature T1. Now the gas changes its state by effecting a
state change so that it reaches the pressure p2, the volume V2 and
the temperature T2 in the new state. The pressure doubles during
this state change, which is an isochore process.

a) Find the work W performed during the isochore process.

b) The heat Q is exchanged between the gas and the surroundings
during the isochore process. Break the ideal gas law as a starting
point, and discuss the sign of heatQ from the gas to the
surroundings to the gas?

Answer #1

Physics_2_2.5
An ideal monatomic gas is in a vessel with the volume V1 = 1m3
under the pressure p1 = 2 105 Pa. The gas is first heated at a
constant pressure to the Volume V2 = 3m3 and then at constant
volume to the pressure p2 = 5 105 Pa. Find the amount of heat Q
supplied to the gas.
A clear process is highly appreciated! Thank you so much for the
help!

A container is filled with an ideal diatomic gas to a pressure
and volume of P1 and V1,
respectively. The gas is then warmed in a two-step process that
increases the pressure by a factor of five and the volume by a
factor of three. Determine the amount of energy transferred to the
gas by heat if the first step is carried out at constant volume and
the second step at constant pressure. (Use any variable or symbol
stated above...
