a railway track has a little distance maintained between the two rails,this is so 'cause during summer they expand and if they don't have distance maintained they bulge causing train accidents and during winter they contract causing the rails to snap
ne heat gives energy for the particles to move around
Solids that expand and contract are balloons and sement on a bridge
Every thing expands an contracts. Some just do so more than others. Glass and wood do very little while metals expand and contract more.
Liquid in thermometers and liquid in a narrow glass tube. Hope this helped!
The solids that have thermal expansion are usually metals which include the pure and the alloys.
It's density decreases.
Yes, especially on heating them.
Their density decreases.
pole
expand
Liquids, solids and gasses EXPAND when heated- the particles occupy more space.
When matter is heated it will expand
they all contract.
Liquids expand more than solids on heating
the heat expand the solids atoms
Mostly they expand as they warm, contract as they cool.
Unlike solids and liquids, a gas will expand to fill the space available to it.
No, gases expand more than solids when heated.
yes
No. They expand.
the intermolecular forces of attraction between the atoms in a solid are weakend due to increase in kinetic energy between molecules
No all solids do not expand at same rate because some solid expand at less temperature and some solids expand at less temperature. For example if we take iron and plastic iron expands at high temperature and plastic melt at less temperature(at candle light also).
Most solids expand as they increase in temperature and contract as they get colder. Interestingly, water after it freezes will start to expand as it gets even colder.
expand
they expand! does that help
BECAUSE the moncules are heated they expand because there gay and expand
