Yes, they do. The phenomenon is called thermal expansion. Every substance has a "coefficient of expansion" figured out via experiment. The coefficient is used in the following way.
change in length = original length * change in Temperature (K) * coefficient of linear expansion
change in volume = original volume * change in Temperature (K) * coefficient of volume expansion
The coefficient of volume expansion is three times the coefficient of linear expansion.
The unit for the coefficient is "per degree" (this makes more sense when you use it in an equation)

∙ 11y agoWhen you heat a solid, you are increasing the kinetic energy of its representative particles. This increases their motion, which in a solid is more of a "vibrating in place" kind of movement, but it's still motion. They're moving more quickly, so they move a little bit farther apart. This is why roads and bridges generally have a small gap built in to them, so that on hot days when the material expands just a bit, it doesn't cause cracks or other structural issues.

Do all liquids expand when heated?
Liquids expand more than solids on heating
Why do liquids expand on heating more than solids?
The answer is a lot more simple than you may imagine, it is simply because the atoms and molecules in liquids havd more freedom to move about than in solids
When most solids liquids and gases are heated they?
expand
How do you make metal contract?
They expand ------- No, normally metals expand when heated.
What happens to solids when they expand?
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
Do all liquids expand when heated?
Liquids expand more than solids on heating
Do all objects expand when heated?
All objects do not expand on heating.....Only metals expand on heating.....non metals like wood,plastic,etc do not expand on heating.
Why do gases expand most on heating and solids least?
That's because of greater intermolecular spaces in gases than in solids
How do solids expand?
the heat expand the solids atoms
Which liquid expand on heating?
All liquids expand on heating (apart from water between 0oC to 4oC)
If solids expand on heating then why we use a scale to measure length knowing that it will expand and contract?
The scale is assumed to expand and contract with the solid - you cannot measure a solid with a 30cm ruler from another continent.
Which of these does not expand liquid solid or gas?
All of them can expand - for example, when they are heated. Gases usually expand more than solids or liquids.
Do solids expand at the same rate?
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).
Why all solids do not change from solid to liquid to gas on heating?
because some solids have extreme strong force of attraction
Why will all solids liquids and gases all expand and contract?
They are all subordinated to temperature variations, which make them contract or expand. This is a physical characteristic for almost all elements.
Unlike solids and liquids a gas will?
Unlike solids and liquids, a gas will expand to fill the space available to it.
What state of matter expands the most on heating?
Solids, liquids and gases expand when heated, liquids and gases expand much more that solids. Gases can be compressed
