A gas is enclosed in a thermally insulated piston-cylinder assembly at 300 K. The gas is compressed by applying an external force on the piston. What will be the correct option for the following thermodynamic parameters?
1
ΔU < 0, q = 0, w > 0
2
ΔU = 0, q = 0, w = 0
3
ΔU > 0, q = 0, w > 0
4
ΔU = 0, q < 0, w > 0
