A glass is filled to the brim with 460.0 mL of water at 100.0 ∘C.

If the temperature of glass and water is decreased to 20.0 ∘C, how much water could be added to the glass?

$\"\"$

The glass of brim contains water of volume 460.0 mL at 100°C

The temperature of glass and water is decreased to 20°C.

Find amount of water added to the glass.

First find the volumetric expansion of water.

Change in volume of water is $\"\"$ , where $\"\"$ is the coefficient of expansion of water $\"\"$

$\"\"$

Change in volume of water is 7.618 mL.
