The key difference between a liquid and a gas is their molecular arrangement. In a liquid, the molecules are loosely packed and have some degree of attraction between them, allowing the liquid to maintain a fixed volume but take the shape of its container. In a gas, the molecules are far apart and have very weak interactions, leading to the gas expanding to fill its entire container.

KEY: - to make into = this is what you do solid - liquid = melting solid - gas/gas - solid = sublimation liquid - solid = freezing liquid - gas = evaporation gas - liquid = condensation They all involve heating up or cooling down the state. Hope this helps(:
The key factor that determines the rising of muffins is the chemical reaction between baking powder and liquid ingredients, which creates carbon dioxide gas bubbles that make the muffins rise.
The process when a liquid turns into a gas is called "vaporization." This can occur through processes such as evaporation, where it happens gradually at the surface of the liquid, or boiling, where it occurs throughout the liquid at a specific temperature. Vaporization is a key component of the water cycle and is essential in various natural and industrial processes.
Vapor and gas are both gaseous states of matter, but they differ in how they are formed. Vapor is a gas that is formed when a substance changes from a solid or liquid state to a gas at a specific temperature and pressure. On the other hand, gas is a state of matter that exists naturally at room temperature and pressure. Vapor is typically denser than gas and can condense back into a liquid or solid form more easily. Gas, on the other hand, is more diffuse and does not easily condense.
The transfer of thermal energy by the movement of a liquid or gas is called convection. In this process, the warmer parts of the liquid or gas rise and the cooler parts sink, creating a circular motion that transfers heat. Convection is a key mechanism for distributing heat in fluids like air and water.
Absorption refrigeration works by using a refrigerant that is absorbed into a liquid solution, which is then heated to release the refrigerant as a gas. The key principles of absorption refrigeration include the use of heat to drive the refrigeration cycle, the absorption of the refrigerant into a liquid solution, and the release of the refrigerant as a gas through heating.
