it stays a gas
Yes, a rock can turn into a gas through a process called sublimation. Sublimation occurs when the solid form of a substance bypasses the liquid state and turns directly into a gas when heated.
they turn into gas
Evaporation.
Molecules move faster when heated -- no matter what state they're in.
When a liquid is heated and changes to its gaseous state, it is called vaporization.
When iodine is heated, it sublimes from a solid state directly into a purple-colored gas. It undergoes sublimation, which means it changes from a solid to a gas without passing through the liquid state.
When water is heated, it can turn into steam, which is essentially water vapor.
If heated sufficiently it will turn into water vapour (steam) which is the gaseous state of water. It will also melt and evaporate.
water vapor (gas state) can turn into water (liquid state) when cooled.
Evaporation is the process and the gas formed by liquid in heated condition is called vapours
Milk doesn't turn into a gas under normal conditions because its boiling point is much higher than room temperature. To turn milk into a gas, it would need to be heated to a temperature above its boiling point to transition into a gaseous state.
Chloroform is a colorless liquid at room temperature. When heated, it may turn to a colorless gas.
