That depends entirely on the solid. Some solids have larger coefficients, some smaller. For example:

Explain formula volume expansion coefficient subject expansion of solid?
Formula for the volume Expansion for a solid is αV=1VdVdT and Isotropic materials is αV=3αL.
Why liquids have two coefficient of expansion?
Liquids have two coefficients of expansion because they can expand in both volume (volume coefficient of expansion) and in area (area coefficient of expansion) when heated. The volume coefficient of expansion relates to changes in the volume of the liquid, while the area coefficient of expansion relates to changes in the surface area.
Is the coefficient of the longitudinal thermal expansion measured only for solid materials Why?
No, the coefficient of longitudinal thermal expansion can also be measured for fluids and gases. This coefficient indicates how much a material will expand or contract in the direction of heat flow due to changes in temperature. It is an important property to consider when designing structures to prevent thermal stress.
Why is it necessary to know the coefficient of linear expansion of solids?
By knowing the coefficient of linear expansion of solids, you can determine how a solid reacts to temperature. Everything reacts to thermal expansion. For instance, a concrete bridge expands when hot, and with the formula for expansion and the coefficient for it, you know just how much that concrete expands and you can plan and build accordingly. That saves lives.
Do all solids expand on heating?
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)
Water expands as it freezes can you define a coefficient of volume expansion for the freezing force?
The coefficient of volume expansion, also known as the volumetric expansion coefficient, is a measure of how much a substance's volume changes per unit change in temperature. For water, the coefficient of volume expansion during freezing is approximately 0.000210 per degree Celsius. This means that for every degree Celsius decrease in temperature, water expands by about 0.000210 times its original volume as it freezes. This expansion is due to the formation of hydrogen bonds in the water molecules' crystal lattice structure, causing them to arrange in a more spread-out pattern.
How thermal expansion takes place in a solid and in a gas?
In a solid, thermal expansion occurs as the temperature increases, causing the atoms or molecules to vibrate more, increasing the average distance between them. As a result, the solid expands in all directions. In a gas, thermal expansion occurs as the temperature increases, causing the gas molecules to move faster and spread out, increasing the volume of the gas.
What is the scientific name for the inrease in the size of a substance when the temperature is increased?
Thermal Expansion. Each liquid or pure solid has a specific thermal of expansion. The thermal expansion of a substance is not linear, though for most of the temperatures we encounter in normal life, it is close enough to linear to be able to use a linear definition called the "Coefficient of Thermal Expansion".
What happens when solids expand?
When solids expand, their particles move farther apart from each other, leading to an increase in volume and size. This expansion occurs due to an increase in thermal energy, causing the atoms or molecules in the solid to vibrate more vigorously and push against each other. The extent of expansion depends on the material's coefficient of thermal expansion, which varies for different substances.
What solids expand when heated?
Most solids expand when heated due to increased thermal energy causing the atoms or molecules within the solid to vibrate more and increase their separation distance from each other. This expansion is governed by the material's coefficient of thermal expansion, which varies depending on the specific solid. Examples include metals, glass, and concrete.
The thermal expansion of a solid is caused by?
The thermal expansion of a solid is caused by an increase in temperature, which leads to the atoms within the solid vibrating more vigorously and occupying a larger volume. As the temperature rises, the atoms move further apart, causing the solid to expand in all directions.
Does a solid have fixed volume?
Yes, a solid has a fixed volume because the particles are tightly packed together and cannot be compressed or expanded easily. This means that the shape of a solid remains constant unless acted upon by an external force.
