Any material with a boiling temperature below 20oc is likely to be a gas at room temperature.
Diagram of room temperature water particles.
When liquids boil the particles must have sufficient energy to break away from the liquid and to diffuse through the surrounding air particles.
This can easily be observed in a water filled bath or.
As these particles cool down and lose energy they will condense and turn back to liquid.
At 373 99 c particles of water in the gas phase are moving very very rapidly.
At any temperature higher than that the gas phase cannot be made to liquefy no matter how much pressure is applied to the gas.
The pressure would increase but the volume would stay the same.
A phase diagram is a graphical representation of pressure and temperature of a material.
10 c 0 c 100 c 110 c which temperatures are the upper and lower fixed points.
In a liquid are.
The strength of bonds attractive forces between particles is different in all three states.
17 the diagram shows four markings on a liquid in glass thermometer.
Notice point e labeled the critical point.
The process in which a liquid substance changes into a gas rapidly on heating is called boiling.
They show the boundaries between phases and the processes that occur when the pressure and or temperature is changed to cross these boundaries.
Liquid to gas change.
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.
Steel plastic and wood are solids 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.
What does that mean.
Boiling or vaporisation defination.
Ice is solid water.
Petrol and water are liquids at room temperature.
Water is the chemical substance with chemical formula h 2 o.
Refer again to water s phase diagram figure above.
Phase diagrams show the state of matter at a given pressure and temperature.
At which point is the temperature the lowest.
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.

The pressure would increase because the temperature increases and the particles would move faster and collide more often.
In a solid are.
