Question

when water freezes its volume increases by 4%. what volume of water is rrequired to make 221 cm cube of ice

Answer 1

Let the volume of water required = x cm^3

Since its volume increases by 4% when it turns into ice, volume of ice = 1.04x

=> 1.04 x = 221

=> x = 221/1.04

=> x = 212.5 cm^3

You need 212.5cm^3 of water.

Let the volume of water required = x cm³

Since its volume increases by 4% when it turns into ice, volume of ice = 1.04x

=> 1.04 x = 221

=> x = 221/1.04

=> x = 212.5 cm³

You need 212.5cm³ of water.
