The brick wall (of thermal conductivity 1.26 W,/m - C) of a building has dimensions of 4.5 m by 6 m and is 6 cm thick. How much heat flows through the wall in a 18.7 h period when the average inside and outside temperatures are, respectively, 30C and 4C7 Answer in units of MLI. An iron nail is driven into a block of ice by a single blow of a hammer. The hammerhead has a mass of (.2 kg and an initial speed of 1.1 m/s. Nail and hammer are at rest after the blow. How much ice melts? Assume the tempera- ture of both the ice and the nail is 0C before and after. The heat of fusion of ice 1s 80 cal /g. Answer in units of g. How much energy is required to change a 40 g ice cube from ice at 14C to steam at 118C? The specific heat of ice is 2090 J/ke - C, the specific heat of water is 4186 J/kg ." C, the specific heat of stream 1s 2010 J/kg -\" C, the heat of fusion is 3.33 x 10 J /kg, and the heat of vaporization is 2.26 x 10 J Jkeg. Answer in units of J. A 40 g block of ice is cooled to T1C. It is added to 553 g of water in an 60 g copper calorimeter at a temperature of 23C. Find the final temperature. The specific heat of copper is 387 J/kg -C and of ice is 2090 J/kg-C. The latent heat of fusion of water is 3.33 x 10 J/kg and its specific heat is 4186 J/kg -C . Answer in units of C. One liter of water at 38\"C is used to make iced tea. How much ice at 0C must be added to lower the temperature of the tea to 13C? The specific heat of water is 1 cal/g - C and latent heat of ice is 79.7 cal/g. Answer in units of gStep by Step Solution
