Question

what is the cofficient of volume expansion of hydrogen​

Answer 1

Answer:

An object of volume V expands to V+ΔV when temperature is increased by ΔT, then volume expansion coefficient αv is given by. αv = (ΔV/V) / ΔT.

The change in volume ΔV is very nearly ΔV = 3αVΔT. This equation is usually written as ΔV = βVΔT, where β is the coefficient of volume expansion and β ≈ 3α. Note that the values of β in Table 1 are almost exactly equal to 3α. In general, objects will expand with increasing temperature.

The ratio of the increase of length, area, or volume of a body per degree rise in temperature to its length, area, or volume, respectively, at some specified temperature, commonly 0° C, the pressure being kept constant.  called also expansivity.
