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 solids expand to a much greater extent than gases when heated?

No, gases expand more than solids when heated.


Do solids expand when hot?

yes


What happens to the volume of solids liquids and gasses as they warm and cool?

As solids are warmed, they expand and their volume increases. Conversely, as solids cool, they contract and their volume decreases. For liquids, warming causes expansion and an increase in volume, while cooling results in contraction and a decrease in volume. Gases behave differently as they expand when warmed and contract when cooled, with volume being directly proportional to temperature.


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).


Do solids change volume?

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.


When most solids liquids and gases are heated they?

expand


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.


What happens to the density of solids liquids and gases when they are heated?

Generally, the density of solids, liquids, and gases decreases as they are heated. When heated, the particles in these substances gain energy and move more, causing the substance to expand, which leads to a decrease in density.


What will expand more when heated gas or solids?

In general, gases expand more than solids when heated. This is because gas particles have more energy and move more freely compared to the more closely packed particles in solids, allowing gases to expand more readily in response to temperature changes.


Do most liquids expand as they get hotter?

Not only liquids but also solids expand as they get hotter, with few exceptions.


How do solids usually behave when heated?

Their volume increases - that is to say, the solids expand. However, their mass stays the same.


How do solids expand?

Solids expand when heated due to an increase in the kinetic energy of their particles, causing them to vibrate more vigorously and push against each other, leading to an overall increase in volume. This expansion occurs uniformly in all directions, resulting in an increase in the dimensions of the solid material.
