Summary

Ice slurries were made from aqueous solutions of ethanol, ethylene glycol and silane coupling agent. The latent heat of melting of ice made from tap water was measured and the uncertainty of the result was 1%. The latent heat of melting of these ice slurries was measured with various concentrations of solution. The latent heat of melting decreased as the solute concentration or the freezing point depression increased. The latent heat of ice slurries made from ethanol or ethylene glycol aqueous solution agreed with that of ice made from pure water known already. The latent heat of melting of ice slurries made from silane coupling agent aqueous solution got smaller than that of ice made from pure water as the freezing point depression increased.
