What is the difference between compression and expansion?
Compression refers to reducing the volume of a substance by applying pressure, resulting in a decrease in its volume. Expansion, on the other hand, is the process of increasing the volume of a substance, typically by applying heat, resulting in an increase in its volume.
What is cubical expansion?
Cubical expansion is the increase in volume that occurs when a substance is heated. This expansion is directly proportional to temperature change, as the molecules in the substance gain kinetic energy and move apart, causing the overall volume to increase. The amount of expansion can be calculated using the coefficient of cubical expansion, which varies for different materials.
What are the three types of heat expansions?
The three types of heat expansions are linear expansion (change in length), area expansion (change in area), and volume expansion (change in volume). Each type of expansion relates to a different physical property of the material when subjected to a temperature increase.
What is expansion of materials?
Expansion of materials refers to the increase in size or volume of a material when subjected to heat. This expansion is caused by the increased kinetic energy of the material's particles, which leads to an increase in their spacing. Different materials have different expansion coefficients, which determine how much they will expand when heated.
The change in an objects volume that occurs when heat is added is called?
thermal expansion

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.
How does volume affect temperature?
Normally there is no affect. In a gas, a CHANGE of volume of a single body, will give a change in temperature. If a gas is compressed the temperature will increase. If a gas is allowed to expand, there will be a reduction in temperature. This principle is used in diesel engines, to ignite the fuel by compression and fridges, where an expansion of gas causes cooling.
What happens if you change an objects volume?
Expansion means that the volume increases......
What is the process of thermal expansion?
Thermal expansion is the tendency of matter to change in volume in response to a change in temperature.
What is compression and expansion of rock is called?
Compression of rock is when external forces push or squeeze the rock, causing it to decrease in volume. Expansion, on the other hand, is when the rock expands or swells due to changes in temperature or pressure.

What is an example problem of a polytropic process?
An example problem of a polytropic process is when a gas undergoes compression or expansion while its pressure and volume change, following a specific mathematical relationship known as a polytropic equation.
What happens when pressure in a fluid changes?
When pressure in a fluid changes, the volume and density of the fluid may also change. If the pressure increases, the volume decreases and the density increases, leading to compression of the fluid. Conversely, if the pressure decreases, the volume increases and the density decreases, causing expansion of the fluid.
