A cube of ice is taken from the freezer at -8.4°C and placed in a 94 g zinc cup filled with 307 g of water. Both the water & the cup are at 20.1°C. Eventually the system reaches thermal equilibrium at 18.4°C. Determine Qcup Qwater (for the water initially in the cup), Qice, & the mass of the ice. Qcup = Qwater Specific heat Solids (J/kg.K) Aluminum 900 Liquids Specific heat (J/kg.K) Brass 402 Bromine 473 Copper 377 Ethyl 2400 Alcohol Glass 840 Gasoline 2220 Gold 126 Glycerin 2430 Ice 2095 Mercury 140 Iron 461 Water 4186 Qice mice = Lead 130 Nickel 502 Latent Heat Substance (J/kg) Silver 239 Steam water 2,260,000 Styrofoam 1131 Ice water 333,000 Zinc 390
