Pressure Change During Gas Compression

Easy Physics Thermodynamics

In a closed system, a gas is compressed from an initial volume of 4.0 liters to a final volume of 1.0 liter while maintaining a constant temperature of 300 K. Based on the principles of thermodynamics, particularly the ideal gas law, how does the pressure of the gas change as a result of this compression?

The pressure decreases because of decreased volume.

The pressure increases because of decreased volume.

The pressure remains constant regardless of volume changes.

The pressure can only be determined with information about the amount of gas present.
