A 235-g sample of a substance is heated to 310 °C and then plunged into a 105-g aluminum calorimeter cup containing 175 g of water and a 17-g glass thermometer at 10.5 °C. The final temperature is 35.0°C. The value of specific heat for aluminium is 900 J/kg · C° , for glass is 840 J/kg · C° , and for water is 4186 J/kg · C° . Part A What is the specific heat of the substance? (Assume no water boils away.) Express your answer using three significant figures.

QUESTION 4 In an isolated system, a 0.255 kg block of gold at 85.0 °C is fully immersed in 0.155 kg of water at 25.0 °C. (specific heat capacity of water, Cwater = 4186 J/kg °C, specific heat capacity of gold, cgald= 129 J/kg °C). Find i. the equilibrium temperature. ii. the energy lost by the gold.
An aluminum cup with mass 0.56 kg holds 0.96 kg of water. Both the cup and the water have a temperature of 10.°C. If a 0.76-kg piece of copper at 53.°C is added to the cup, what is the final equilibrium temperature in °C? You may assume that the cup, water, and copper are well insulated from anything else.
Q2/ A 4-m-internal-diameter spherical tank made of 1.75-em-thick stainless steel (k 15 W/m °C) is used to store iced water at 0°C. The tank is located in a room whose temperature is 35°C. The walls of the room are also at 35°C. The outer surface of the tank is black, and heat transfer between the outer surface of the tank and the surroundings is by natural convection and radiation. The convection heat transfer coefficients at the inner and the outer surfaces of the tank are 80 W/m2 °C and 10 W/m2 °C, respectively. Determine (a) the rate of heat transfer to the iced water in the tank and (b) the amount of ice at 0°C that melts during a 1-h period. The heat of fusion of water at atmospheric pressure is hif 334 kJ/kg.
An insulated beaker with negligible mass contains liquid water with a mass of 0.330 kg and a temperature of 60.5 °C. Part A How much ice at a temperature of -18.5 °C must be dropped into the water so that the final temperature of the system will be 40.0 °C? Take the specific heat of liquid water to be 4190 J/kg K, the specific heat of ice to be 2100 J/kg K, and the heat of fusion for water to be 3.34x105 J/kg.
