The coefficient of volumetric expansion of water is 2.5 × 10-^4/°C. If the temperature of 20 liters of water increases by 15°C, how much will the volume of the water increase by?

Answer 1

This is subject to the current temperature of water, as the coefficient changes at its initial temperature.

If the coefficient of volumetric expansion of water is 2.5 x 10^-4 / degrees C, then

dV = V(Coeff)(dT)

dV = volume change

V = volume

dT = temperature change

dV = 20L x (2.5 x 10^-4 / degrees C) x 15C

dV = 4.5 x 10^-2 Lor 0.045 Liter change

Hope this Helps!
