How is solid different from liquid?
Solids have a definite shape and volume. Liquids have a definite volume, but take the shape of the container.
What is the movement of particles in gases?
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.
What is the movement of solid particles?
The particles in a solid are tightly packed and locked in place. Although we cannot see it or feel it, the particles are moving = vibrating in place. The particles in a liquid are close together (touching) but they are able to move/slide/flow past each other.
What are the five properties of solid liquid and gas?
Characteristics of Solids, Liquids, Gases
- strong intermolecular forces.
- particles vibrate in place.
- low kinetic energy (KE)
- definite shape.
- definite volume.
- incompressible.
- high density (as compared to same substance as a liquid or gas)
- low rate of diffusion (millions of times slower than in liquids)
What are the three properties of solids?
1 Answer
- A solid has a definite shape and volume.
- Solids in general have higher density.
- In solids, intermolecular forces are strong.
- Diffusion of a solid into another solid is extremely slow.
- Solids have high melting points.
What is the Vapour pressure of liquid?
Vapour pressure is a measure of the tendency of a material to change into the gaseous or vapour state, and it increases with temperature. The temperature at which the vapour pressure at the surface of a liquid becomes equal to the pressure exerted by the surroundings is called the boiling point of the liquid.
What is pressure in a liquid?
Liquid pressure is the increase in pressure at increasing depths in a liquid. This pressure increases because the liquid at lower depths has to support all of the water above it. We calculate liquid pressure using the equation liquid pressure = mass x acceleration due to g density x depth in fluid. liquid pressure.
