Latent heat of fusion is the heat given up as a substance freezes. The latentheat of fusion for water is 144 British thermal units per pound (Btu/lb). Thismeans that 144 Btu are given up for each pound of water that freezes. Howmany British thermal units of heat are given up when 4,000 pounds of waterfreeze?
