What state of matter is condensation?
Condensation is when a gas becomes a liquid. It happens when a gas, like water vapor, cools down. Photo from: Wikimedia Commons. Evaporation and condensation are two processes through which matter changes from one state to another.
What states of matter does water transition between during evaporation?
Phase Transition: Liquid to Gas Vaporization of a sample of liquid is a phase transition from the liquid phase to the gas phase. There are two types of vaporization: evaporation and boiling. Evaporation occurs at temperatures below the boiling point, and occurs on the liquid’s surface.
What phase change happens during condensation?
Condensation is the phase change in which a substance changes from a gas or vapor to a liquid. Condensation is an exothermic process.
Which state of matter has the most movement of its particles?
Is liquid can be compressed?
Like a gas, a liquid is able to flow and take the shape of a container. Most liquids resist compression, although others can be compressed. Unlike a gas, a liquid does not disperse to fill every space of a container, and maintains a fairly constant density.
What is the movement of 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.
Why can gas and liquid particles move around?
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.
Does volume decrease as pressure increases?
this relationship between pressure and volume is called Boyle’s law. So, at constant temperature, the answer to your answer is: the volume decreases in the same ratio as the ratio of pressure increases.
What is PV is equal to nRT?
At constant temperature and volume the pressure of a gas is directly proportional to the number of moles of gas. Or you could think about the problem a bit and use PV=nRT. N2O is placed in a piston. See, if you forget all those different relationships you can just use PV=nRT.
What units are used in PV nRT?
In SI units, p is measured in pascals, V is measured in cubic metres, n is measured in moles, and T in kelvins (the Kelvin scale is a shifted Celsius scale, where 0.00 K = −273.15 °C, the lowest possible temperature).
