Q.54 Explain the effect of pressure on solid, liquid and gas ?
Answers
Effect of pressure on solid :
(i) There is no effect of pressure on solids
(ii) Solids are non - compressible
(iii) When the pressure is increased on a solid, it is deformed and finally broken down.
Effect of pressure on liquid :
(i) There is no effect of pressure on liquid
(ii) Liquids are non - compressible i.e liquids cannot be compressed since there is not enough space between their particles to get compressed
Effect of pressure on gas :
(i) The volume of gas decreases with increase in pressure
(ii) Since there is lot of space between particles of gas, gas is highly compressible.
Answer:
As the temperature of a solid, liquid or gas increases, the particles move more rapidly. As the temperature falls, the particles slow down. ... If the pressure above a liquid is increased sufficiently, the liquid forms a solid. If the pressure above a liquid is decreased sufficiently, the liquid forms a gas.
