Yes, gas can be transformed into a solid and a liquid, but it requires a change in temperature and pressure. This process is called phase change. Here's how it works:

* Gas to Liquid (Condensation): When you cool a gas down, the molecules slow down and lose energy. This makes them more likely to stick together, forming a liquid. You can also increase the pressure on a gas, forcing the molecules closer together and causing them to condense.

* Gas to Solid (Deposition): If you cool a gas down even further (or increase the pressure even more), the molecules will lose even more energy and become locked into a fixed position, forming a solid.

Examples:

* Water: Water vapor (gas) condenses into liquid water when it cools down, and can freeze into ice (solid) if it gets cold enough.

* Carbon Dioxide: Dry ice is solid CO2, formed by putting CO2 gas under pressure.

* Nitrogen: Liquid nitrogen is used in medical and industrial applications.

Key Concepts:

* Temperature: Lower temperatures reduce the energy of gas molecules, making them more likely to condense.

* Pressure: Higher pressure forces gas molecules closer together, increasing the chance of them sticking together.
