    Does Water Expand Or Contract When Heated?

    As a solid, ice can only expand linearly, which means the length and width of an ice cube can change. The coefficient of linear expansion for ice, which measures fractional change of length and width per degree Kelvin, is a constant 50 x 10-6÷ K.

    This means that ice expands in a uniform amount with each degree of heat you add to it.

    When ice becomes liquid water, it no longer has fixed linear dimensions, but it has volume. Scientists use a different thermal coefficient — the coefficient of volume expansion — to measure the response of liquid water to temperature.

    When water vapour cools down it forms

    This coefficient, which measures fractional changes in volume per degree Kelvin, is not fixed. It increases with mounting temperature until the water starts boiling. In other words, liquid water expands at an increasing rate as the temperature goes up.

    When water turns into steam, it expands according to the ideal gas law: PV = nRT.

    If the pressure (P) and number of moles of vapor (n) maintain at a constant, the volume of steam (V) increases linearly with temperature (T). In
