Expansion means increase in the volume. When the substances are heated the
K.e of the molecules is increased to a certain level that they exerts pressure on each other and collide with themselves. there negligible I.M.F begin to decrease more further and in this the molecules become widely seperated from eachothe hence, the substance is expanded.
This happens because heat is actually the vibration of atoms or molecules. The hotter a substance is the more violently the atoms move and therefore the larger the space they take up - as they are taking up more room the whole solid object made from them has to get bigger - it expands.
when substance heated,their intermolecular bonding is break at required temperature,there for molecules are free to move;thus substances are expand when heated.
The particles move around mor and more abd take up more space
the substance expands when heated because the particles that make up the substance is trying to get out and escape the heat.
the particle vibrated more rapidly causing the object to expand
because its molicules will broken out while heating
When a substance is heated, the molecules absorb heat energy and begins to vibrate to and fro thereby slightly expanding the substance.
They expand
They expand due to the molecules speeding up.
Generally speaking, substances have the least amount of surface area as a solid, as they are heated they form a liquid and expand, as this is heated it forms a gas and expands more. *Assuming pressure is constant **Water is the only substance to expand as it freezes
Yes, in general a liquid will expand when heated. They contract when they are cooled.

A substance in the solid phase will typically expand when heated. Most substances when heated sufficiently will melt into a liquid, assuming that they do not combust or sublimate.
Ice (frozen water) and Water (below 4 oC) expand when cooling. This is exceptional! Other substances, also Water (above 4 oC) expand when heated.
It contracts when heated from 0 deg C to 4 deg C. Other substance expand when heated.
