No, hot water poured into a cup is in liquid form, not a gas. At higher temperatures, water molecules move more quickly and can evaporate into steam, which is the gaseous form of water.
neither. the water needs to be boiling to create gas. Hot water will not create gas and cold water will not create gas. Yes, hot water will create gas more quickly than cold if boiled tho
A fragrance would reach you more quickly in a hot room because molecules move faster at higher temperatures, allowing the scent to disperse more rapidly through the air.
When you sat hot, I am guessing that you meant during an increase of temperature. Assuming that one is only directly changing the temperature and not the pressure or volume; the particles will begin to spread further apart, as well as vibrate more quickly. The rate of reaction will also increase because more effective collisions are taking place. More energy is also being supplied to the system in the form of heat.
Hot particles have more kinetic energy, which causes them to move faster compared to cooler gas particles. The increased temperature leads to a greater average speed of the hot particles, resulting in faster movement within the gas.
when its hot outside
Hot water. Higher temperature means more kinetic energy, and energy is needed to change phases from liquid to gas (evaporation.)
Raisins plump up more quickly in hot water because the molecules in hot water move quicker than molecules in cold water so the hot water molecules diffuse quicker into the raisin.
In hot areas the molecules move quickly and in cold areas the molecules move slower.
Hot air particles have more energy and move more quickly compared to cold air particles, which have less energy and move more slowly. This results in hot air being less dense and rising, while cold air is denser and sinks.
