Answer: 8855 Joules energy is released when 115 g of [tex]CHCl_3[/tex] changes from a liquid to a solid at its freezing point.
Explanation:
Latent heat of freezing is the amount of heat released to convert 1 mole of liquid to solid at atmospheric pressure.
Amount of heat released to freeze 1 gram of [tex]CHCl_3[/tex] = 77 J/g
Mass of [tex]CHCl_3[/tex] given = 115 gram
Heat released when 1 g of [tex]CHCl_3[/tex] is freezed = 77 J
Thus Heat released when 115 g of [tex]CHCl_3[/tex] is freezed =[tex]\frac{77}{1}\times 115=8855J[/tex]
Thus 8855 Joules energy is released when 115 g of [tex]CHCl_3[/tex] changes from a liquid to a solid at its freezing point.
