Heat is the average kinetic energy of the molecular (or sub-molecular) consituents of matter. The faster the molecules are vibrating, the hotter the material is. And faster vibrations are going to have larger amplitudes as well, so the molecules will take up more space, and the size of the object therefore increases as it gets hotter - in most cases. Phase changes can cause other effects, such as the well-known phenomenon that water increases in volume as it freezes, because ice has a crystaline structure that takes up more room than liquid water. But it is still true that as the ice gets progressively colder, it shrinks, just like any other material substance.

Thermal expansion is the tendency of matter to change in volume in response to change in temperature. During thermal expansion, the density of a substance decreases as its volume increases. Volume is the space occupied by a body. So, when a substance expands on heating, it will occupy more space or will have more volume. But its mass does not change because the amount of matter contained in a body cannot change. Therefore, mass divided by increased volume gives a decreased density.
The increase in volume of a substance due to an increase in temperature is called thermal expansion. This occurs because as the temperature of a substance rises, the particles within it gain energy and move more, causing them to spread out and increase in volume.
thermal expansion
Yes as friend Des Dichado pointed out liquids do have thermal expansion.
A bridge must have expansion gaps or else they will waver when they expand in warm temperatures. This is thermal expansion
thermal expansion
Chemical reactions and magnetic fields are not examples of thermal expansion. Thermal expansion specifically refers to the increase in size of a material when heated and the decrease in size when cooled.
Linear expansion and volumetric expansion are the two types of thermal expansion. Linear expansion is the increase in length of a material when heated, while volumetric expansion refers to the increase in volume of a material when heated.
Thermal expansion is the tendency of a material to change in volume, length, or area in response to a change in temperature. The two main types of thermal expansion are linear expansion, where an object grows in length in one dimension, and volumetric expansion, where an object expands in all dimensions.
Thermal expansion is the tendency of matter to change in volume in response to a change in temperature.
thermal expansion depends on Temperature and material of steel
The material with the highest coefficient of thermal expansion is typically graphite.
No, the mass of an object does not change during thermal expansion. Thermal expansion results in an increase in volume and dimensions of the object, but the mass remains constant.
