When does expansion occur?
Expansion occurs when there is a change in volume due to increased temperature. Contraction occurs when there is a decrease in volume due to decreased temperature.
What happens to density of a substance during thermal expansion?
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 change in an objects volume that occurs when heat is added is called?
thermal expansion
What is an increase in an objects volume when its heated?
Perhaps coincidentally, that physical change is called "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.
Will the volume change in the container?
Yes, depending on what material it's made of, it would have a different coefficient of thermal expansion. Materials expand with heat.
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.
How does compressing a gas affect volume?
Compressing a gas means increasing the pressure on the gas and according to Boyle's law pressure is inversely proportional to the volume of a given amount of a gas(at constant temperature) . Therefore increasing the pressure (compression) of the gas reduces the volume of the gas.
When does expansion occur?
Expansion occurs when there is a change in volume due to increased temperature. Contraction occurs when there is a decrease in volume due to decreased temperature.
Is the volume expanded and the volume compressed during carnot cycle is equal?
Since it is a CYCLE, the overall volume change from minimum volume to maximum volume and back must sum to zero, thus the volume expanded must equal the volume compressed. Now, bear in mind that the Carnot Cycle consists of 4 steps:Reversible isothermal expansion of the gas at the "hot" temperature, T1 (isothermal heat addition or absorption).Isentropic (reversible adiabatic) expansion of the gas (isentropic work output).Reversible isothermal compression of the gas at the "cold" temperature, T2. (isothermal heat rejection)Isentropic compression of the gas (isentropic work input).Although when you graph the cycle on a PV diagram, it looks pretty similar, there is no requirement that the volume change in step 1 matches the volume change in step 3, nor that the volume change in step 2 match that in step 4.
What is the volume co-efficient of expansion of liquid if its volume doesn't change on heating?
zero, if it doesn't expand. ------ But is impossible to heat without any volumic expansion.
