What happens to the particles of a gas when it is condensed?
The atoms, ions, or molecules that make up the solid or liquid are very close together. There is no space between the individual particles, so they cannot pack together. When a gas is compressed, as when the scuba tank is being filled, the gas particles are forced closer together.
What does it mean for a gas to be condensed?
Condensation is the change of the state of matter from the gas phase into the liquid phase, and is the reverse of vaporization. The word most often refers to the water cycle. When the transition happens from the gaseous phase into the solid phase directly, the change is called deposition.
What happens when a substance is condensed?
A substance condenses when the pressure exerted by its vapour exceeds the vapour pressure of the liquid or solid phase of the substance at the temperature of the surface where condensation occurs. Unless this heat is removed, the surface temperature will increase until it is equal to that of the surrounding vapour.
Can a gas be condensed?
The atoms and molecules in gases are much more spread out than in solids or liquids. They vibrate and move freely at high speeds. Gas can be compressed much more easily than a liquid or solid. (Think about a diving tank – 600 L of gas is compressed into a 3 L cylinder.)
What are the particles in a gas?
Gas In a gas, particles are in continual straight-line motion. The kinetic energy of the molecule is greater than the attractive force between them, thus they are much farther apart and move freely of each other. In most cases, there are essentially no attractive forces between particles.
When a gas is condensed the distance between the molecules increases or decrease?
Answer: At room temperature and standard pressure, the average distance between gas molecules is about ten times the diameter of the molecules themselves. When a gas is compressed, as when the scuba tank is being filled, the gas particles are forced closer together.
Which statement best describes what happens when a substance condenses?
Condensation is the change of a gas to a liquid.
When the gas is condensed the distance between the particles?
Answer: When a gas is compressed, as when the scuba tank is being filled, the gas particles are forced closer together and thus the distance between the molecules decreases.
What happens to the particles of a gas during condensation?
This breaks bonds holding them together as a solid and the particles become gases during sublimation. During condensation the opposite occurs. Particles are losing heat energy which means a loss of kinetic energy slowing the particles down to the point that the attractive forces form bonds causing the gas to become a liquid.
What happens to particles when a substance is cooled?
When a substance is cooled, its internal energy decreases: the movement of its particles decreases. bonds between particles form when a substance condenses or freezes, or sublimes to form a solid from a gas. What happens to particles during sublimation?
When does a solid change to a gas?
The process in which a solid changes directly to a gas is called sublimation. It occurs when the particles of a solid absorb enough energy to completely overcome the force of attraction between them. Solid carbon dioxide changes directly to the gaseous state.
What happens to the volume of gas during compression?
During compression, the volume (V) of a gas decreases. When this happens, the pressure (P) of the gas increases if the number of moles (n) of gas remains constant. If you keep the pressure constant, reducing the temperature (T) also causes the gas to compress.
