Consider the isothermal compression of 0.1 moles of an ideal gas at 300 K from (P1=1.5 bar,V1=2 dm3) to (P2=3 bar,V2=1 dm3). The curve illustrates the internal pressure/volume relationship for the ideal gas at 300 K.
If the compression of the gas is carried out reversibly, which of the following statements is TRUE?
There will be no energy transferred as heat.
The change in the energy, U, will be positive.
The work required is the minimum for this compression
The gas will cool (the temperature of the gas will go down)
