It is exothermic because the gas is expanding. Most processes that have to do with expansion are exothermic/
The liquid to gas phase transformation (evaporation) is an endothermic process. It requires heat to be accomplished. The gas to liquid phase transformation (condensation) is an exothermic process. The vapor releases heat while condensing into a liquid.
Yes.
The random motion of the gas molecules allows them to diffuse throughout the space available to them.
No, there are trace amounts of gas and dust.
The law of diffusion. It states that " at constant temperature, the rate of diffusion of any gas is inversely proportional to the square root of its density".
A diffusion pump works by using a high-speed jet of vapor to push gas molecules out of a chamber, creating a low-pressure environment. The vapor jet collides with gas molecules, transferring momentum and pushing them towards the pump's outlet. This process continues until a high vacuum is achieved in the chamber.
It is exothermic. The gas must release energy to its surrounding to become a liquid.
What kind of diffusion? If it is diffusion of molecules then gas would be the right platform
Diffusion - when particles move from an area of high to lower concentrationEffusion - when gas molecules escape from their container through tiny holes in the container.
Solid to gas (sublimation) is endothermic (takes in heat).In other words:A phase change from the solid state to the gas state is endothermic.Sublimation is endothermic (takes in energy).Heat energy must be provided to make it work.When there is a change of state from a solid to a liquid, a solid to a gas, or a liquid to a gas, at a constant temperature, the process is endothermic NOT exothermic. It requires energy to break the intermolecular forces that keep the molecules together, and that reduces the temperature - heat is taken in.
When natural gas is burned in a furnace, it undergoes an exothermic reaction, which means it releases heat. The combustion of natural gas produces carbon dioxide, water vapor, and heat energy as byproducts.
Yes, exothermic means that there is heat in the "project."
No, it is the lightest gas of the universe so has the highest rate of diffusion.
yes
Condensation is considered a type of exothermic reaction. Condensation is something that is released, which means that is exothermic instead of endothermic.
Gas devolve reactions are exothermic. So it is a exothermic too.
Drain cleaner is typically exothermic. When it is mixed with water, it produces heat as a result of an exothermic chemical reaction. This heat helps to dissolve and remove the clogs in the drain.
