A glass jar has an internal volume of 500 cm³ at 25°C. If the coefficient of volume expansion for glass is 30 x 10^-6 /°C, what will be the volume of the jar when the temperature rises to 50°C?

Change in volume = (coefficient of volume expansion) x (original volume) x (change in temperature)

   Change in volume = (30 x 10^-6 /°C) x (500 cm³) x (50°C - 25°C)

   Change in volume = 30 x 10^-6 x 500 x 25

   Change in volume = 0.375 cm³

 

   Volume of the jar at 50°C = original volume + change in volume

   Volume of the jar at 50°C = 500 cm³ + 0.375 cm³

   Volume of the jar at 50°C = 500.375 cm³
