What is the order of expansion in solid liquid and gas?
Answer: a)effect of pressure-increasing order: solid. Reason: As we heat, the molecules gain K.E and move faster hence gases expand faster than solids and liquids.
What is gas expansion?
The expansion of a gas occurs whenever it is heated. Heating a gas increases the kinetic energy of the particles, causing the gas to expand.
Do particles vibrate in a solid?
In a solid, the particles pack together as tightly as possible in a neat and ordered arrangement. The particles are held together too strongly to allow movement from place to place but the particles do vibrate about their position in the structure.
What causes the thermal expansion of solids liquids and gases?
Describe qualitatively the thermal expansion of solids, liquids and gases. When matter is heated, its particles gain energy, which is exerted as kinetic energy. In solids, the particles vibrate harder and faster, creating more space between the particles, causing them to expand. This is most visible in metals.
What is expansion and contraction in solids liquids and gases?
Expansion and Contraction in Solids, Liquids and Gases. Some materials expand on heating and some contract on cooling. Heating makes the particles (that form the material) expand or become loose. Cooling makes the particles (that form the material) contract or become tight.
What is an example of expansion in a solid?
In a solid, expansion occurs when it is heated. According to the particle theory of matter, when particles are heated they move faster and expand. An example of expansion in a solid is railroad tracks and how they leave spaces between the track, so during the summer they have room to expand in the hot weather.
Why do solids expand and liquids expand differently?
Relative expansion of solids, liquids and gases Solids, liquids and gases expand by different amounts when you heat them. Solids only expand by a small amount. The reason for this is that the particles in a solid are held in place by very strong solid bonds.
