explain with the help of formula the expansion coefficients of liquid and gas
Answers
Answer:
Explanation:
Expansion coefficient of a liquid or a gas is a parameter which denotes its ability to expand with an increase in temperature. ... Gases have no fixed volume and its volume change is measured at constant pressure.
Answer:
The formulae for the expansion coefficients of liquid and gas is discussed below:
V2 = V1 (1+β∆T)
or β = (V2-V1/V1) 1/∆T
From the above formula, we can say that –
A liquid does not have a definite shape but it has a definite volume. The volumetric expansion coefficient for a liquid (β) is defined as the fractional change in the volume of the liquid per °Celsius (or kelvin) change in temperature.
A gas does not even have a fixed volume. The expansion of a gas is measured by keeping its pressure constant. This volumetric expansion coefficient is called the constant pressure expansion. Here, ∆T is the change in temperature and V1 and V2 are the initial and final volumes of the gas at constant pressure. β is the constant pressure expansion coefficient of the gas.
