Answer:
1. When a gas barrel is filled with gas, the gas is compressed into liquid form. The compression process takes place when the gas is compressed by the weight of the gas above it. This compression process causes the gas to become liquid.
2. Once the gas leaves the barrel, it returns to its gaseous form. This change back to gas occurs because the pressure on the gas is released when it exits the barrel. This decrease in pressure causes the gas to expand and return to its gaseous form.
