Steel plastic and wood are solids at room temperature.
Diagram of room temperature water particles.
Refer again to water s phase diagram figure above.
Any material with a boiling temperature below 20oc is likely to be a gas at room temperature.
As these particles cool down and lose energy they will condense and turn back to liquid.
17 the diagram shows four markings on a liquid in glass thermometer.
In a liquid most of the particles are close together.
At which point is the temperature the lowest.
What does that mean.
At any temperature higher than that the gas phase cannot be made to liquefy no matter how much pressure is applied to the gas.
When liquids boil the particles must have sufficient energy to break away from the liquid and to diffuse through the surrounding air particles.
A phase diagram is a graphical representation of pressure and temperature of a material.
In a solid are.
Water is the chemical substance with chemical formula h 2 o.
Notice point e labeled the critical point.
The process in which a liquid substance changes into a gas rapidly on heating is called boiling.
This can easily be observed in a water filled bath or.
Water is a tasteless odorless liquid at ambient temperature and pressure liquid water has weak absorption bands at wavelengths of around 750 nm which cause it to appear to have a blue colour.
Liquid to gas change.
In a liquid are.
Petrol and water are liquids at room temperature.
The temperature at which a liquid boils and changes rapidly into a gas at atmospheric pressure is called boiling point of the liquid.
At 373 99 c particles of water in the gas phase are moving very very rapidly.
They show the boundaries between phases and the processes that occur when the pressure and or temperature is changed to cross these boundaries.
Ice is solid water.
One molecule of water has two hydrogen atoms covalently bonded to a single oxygen atom.
The pressure would increase but the volume would stay the same.
Phase diagrams show the state of matter at a given pressure and temperature.
As we increase the temperature the pressure of the water vapor increases as described by the liquid gas curve in the phase diagram for water and a two phase equilibrium of liquid and gaseous phases remains.

The strength of bonds attractive forces between particles is different in all three states.
