1. When gas is heated, what is the process called?When a gas is heated, its particles move faster, gaining thermal energy. Depending on the context, here are a few processes that could be happening:If it's just getting hotter, the process is called heating or thermal expansion.If a liquid turns into gas by heating, that’s called evaporation or boiling.If a solid turns directly into gas, that process is called sublimation.But if you’re simply asking what happens when a gas is heated, the best general answer is:➡️ Thermal expansion — gas particles spread out and move faster.️ 2. When gas is heated, what three different states of matter is it related to?When you heat a gas, it can be connected to all three common states of matter:Solid – If you cool gas enough, it can go through condensation → liquid, then freezing → solid.Liquid – Gases come from liquids (through boiling or evaporation).Gas – This is the state being heated.So, the three states of matter related to a gas (especially when heating or cooling it) are:➡️ Solid, Liquid, GasThese changes happen through melting, freezing, evaporation, condensation, sublimation, and deposition — all part of the matter cycle.
