No, they vary
It means expanding and contracting at the same speed.
If the contraction occurred at the same rate as the expansion has, then it would take about fifteen billion years.
the matter always stays the same, expansion and contraction just means the matter is becoming more/less spread out from one another. A change in the state of matter is turning from solid-liquid-gas. The amount of matter always stays the same!
No, all solids do not expand and contract by the same amount. The amount of expansion or contraction depends on the material's coefficient of thermal expansion, which varies from one material to another. Different solids have different responses to changes in temperature.
No, liquids do not expand and contract at the same rate. Different liquids have different coefficients of expansion, which determine how much they expand or contract with changes in temperature. This property is important when designing systems where temperature changes may affect the volume of the liquid.
Contraction is basically when an object(solid) reduces in size due to internal or external forces. Expansion is when the object increases in size due to thse same forces (eg. gravity, pressure.) Liquids and gases cannot expand or contract.
Expansion allows solids to accommodate changes in temperature without breaking, while contraction helps to maintain structural integrity during cooling. These processes are important for preventing damage and maintaining stability in solid materials under varying conditions.
No, it depends upon the nature of liquid.
The contraction form of "it had" is it'd (it-ud). The same contraction is used for "it would."
If a liquid and gas are in equilibrium, it means that the rate of evaporation is equal to the rate of condensation. This indicates that the system has reached a balance between the liquid and gas phases with no net change in the amount of substance transitioning between the phases.
liquid molecules forming a gas and gas molecule forming a liquid are equal in number
The contraction for he has is he's, which is the same contraction used for he is. For example, "he's gone away". The same is true for other third-person pronouns: she's is the contraction for both she is and she has, and it's is the contraction for both it isand it has.
