Water freezes into ice of density $920 kg / m^{3}$ (water $1000 kg / m^{3}$ ). By what percentage does its volume increase on freezing (1 decimal)?

Answer:

8.70

Solution:

$V_{ice} / V_{water} = 1000/920 = 1.087$ , i.e. $8.7%$ increase. In a closed pipe this expansion creates pressure that can burst it.
