Final answer:
When a gas is compressed into a liquid, it takes up a smaller volume, which has several advantages. These include reduced pressure, increased density, and decreased temperature. These advantages make it easier to store and transport the substance.
Step-by-step explanation:
When a gas, such as carbon dioxide, is compressed into a liquid, it takes up a smaller volume. This has several advantages. One advantage is that it reduces the pressure of the gas. When the same number of gas molecules are squeezed into a smaller volume, the pressure increases. Conversely, when the gas is compressed into a liquid, the pressure is reduced. Another advantage is that the liquid form of the gas has increased density compared to the gas form. This increased density allows for easier storage and transportation of the substance. Lastly, when a gas is compressed into a liquid, it typically results in a temperature decrease. This can be useful in certain applications where lower temperatures are desired or required.
