- (a) You have a styrofoam container with 815 g of a soft drink (specific heat of 4,100 J/(kg · °C)) at 29.0° and you add a 60 g chunk of ice at 0°C. Assume the liquid and water mix uniformly as the ice melts and determine the final temperature of the mixture (in °C). 375.31 X Since the mixture is thermally isolated, the heat gained by the ice and the associated ice water is equal to the heat lost by the liquid. Write expressions for the heat gained by the ice as it changes from a solid to a liquid, gained by the ice water as it warms to the final temperature, and lost by the liquid as it cools to the final temperature. °C (b) What If? What is the minimum mass of the ice cube (in g) that will result in a final mixture at exactly 0°C? 290.1 gA 0.50 cm thick piece of copper has an area of 4.0 cm2. One side of the copper is ata temperature of 100° C, and the other side is at 400° C. At what rate does energyflow through the copper?Following vigorous exercise, the internal body temperature of a 69.5-kg person is 40.0°C. At what rate, in watts, must the person transfer thermal energy to reduce the body temp. 37.0 C in 30.0 min, assuming the body continues to produce energy at the rate of 150W?
- What mass of water at 28.0°C must be allowed to come to thermal equilibrium with a 1.70-kg cube of aluminum initially at 150°C to lower the temperature of the aluminum to 62.0°C? Assume any water turned to steam subsequently recondenses. kgLake Erie contains roughly 4.00 ✕ 1011 m3 of water. How much energy is required to raise the temperature of that volume of water from 18.0°C to 21.0°C? How many years would it take to supply this amount of energy by using the 1,400-MW exhaust energy of an electric power plant?A styrofoam cooler (k = 0.030 W/(m-°C) has outside dimensions of 0.170 m x 0.250 m x 0.260 m, and an average thickness of 2.0 cm. How long will it take for 1.10 kg of ice at -5.0°C to melt (to water at 0°C) in the cooler if the outside temperature is 34.0°C? Assume that ice temperature increases linearly from -5.0°C to 0°C. Neglect any temperature change of the air in the cooler. Data: Specific heat of ice is 2050 J/(kg-K). Laten heat of fusion of water is 3.34×105 J/kg.
- Thank you!(a) How much heat transfer (in kcal) is required to raise the temperature of a 0.650 kg aluminum pot containing 3.00 kg of water from 10.0°C to the boiling point and then boil away 0.600 kg of water? X kcal Enter a number. (b) How long (in s) does this take if the rate of heat transfer is 600 W (1 watt = 1 joule/second (1 W = 1 J/s))?What mass of water at 20.0°C must be allowed to come to thermal equilibrium with a 1.95-kg cube of aluminum initially at 150°C to lower the temperature of the aluminum to 60.0°C? Assume any water turned to steam subsequently recondenses. kg
- If 4.00 × 104 J of heat energy is required to turn water ice at −10.0º C to steam at 100º C, what was the mass of the block of ice? Note– this is not a sublimation problem.A 160 g copper bowl contains 120 g of water, both at 25.0°C. A very hot 420 g copper cylinder is dropped into the water, causing the water to boil, with 5,00 g being converted to steam. The final temperature of the system is 100°C. Neglect energy transfers with the environment. (a) How much energy is transferred to the water as heat? (b) How much to the bowl? (c) What is the original temperature of the cylinder? The specific heat of water is 1 cal/g-K, and of copper is 0.0923 cal/g-K. The latent heat of vaporization of water is 539 Cal/kg.What mass of water at 20.0°C must be allowed to come to thermal equilibrium with a 1.90-kg cube of aluminum initially at 150°C to lower the temperature of the aluminum to 70.0°C? Assume any water turned to steam subsequently recondenses. kg
