- Q:33)Occasionally, huge icebergs are found floating on the ocean's currents. Suppose one such iceberg is 138 km long, 28.1 km wide, and 247 m thick. (a) How much heat in joules would be required to melt this iceberg (assumed to be at 0 °C) into liquid water at 0 °C? The density of ice is 917 kg/m³. (b) The annual energy consumption by the United States in 1994 was 9.3 x 10¹⁹ J. If this energy were delivered to the iceberg every year, how many years would it take before the ice melted? (a) Number (b) Number Units UnitsAn automobile has a mass of 1,547 kg, and its aluminum brakes have an overall mass of 10.2 kg. (a) Assuming all the internal energy transformed by friction when the car stops is deposited in the brakes and neglecting energy transfer, how many times could the car be braked to rest starting from 29.0 m/s before the brakes would begin to melt? (Assume an initial temperature of 20.0°C. Count only the number of times the car can come to a complete stop without the brakes melting in the process. The melting point of aluminum is 660°C.)
- A small electric immersion heater is used to heat 82 g of water for a cup of instant coffee. The heater is labeled “150 watts” (it converts electrical energy to thermal energy at this rate). Calculate the time required to bring all this water from 25°C to 100°C, ignoring any heat losses. (The specific heat of water is 4186 J/kg·K.)A family comes home from a long vacation with laundry to do and showers to take. The water heater has been turned off during the vacation. If the heater has a capacity of 50.0 gallons and a 4,500-W heating element, how much time is required to raise the temperature of the water from 20.0°C to 55.0°C? Assume the heater is well insulated and no water is withdrawn from the tank during that timeAn uninsulated container holds 3.5 mol of an ideal gas at an initial temperature of 300 K. The gas is compressed by a movable piston, and 500 J of work is done on the gas while being compressed. If the final temperature of the gas is 400 K, how much heat flows in or out of the gas during this process?
- A 155 g copper bowl contains 230 g of water, both at 20.0°C. A very hot 300 g copper cylinder is dropped into the water, causing the water to boil, with 4.05 g being converted to steam. The final temperature of the system is 100°C. Neglect energy transfers with the environment. (a) How much energy (in calories) is transferred to the water as heat? 8.6 X kcal (b) How much energy (in calories) is transferred to the bowl? 55 X kcal (c) What is the original temperature of the cylinder? 553.6 X °C Did you use the idea of conservation of energy? That is, did you equate the sum of the energy transfers to zero? For the bowl and cylinder, did you substitute the expression relating an energy transfer, the specific heat, the mass, and the temperature change? For the water, did you use the same expression to get the water to the boiling point? Did you also include an expression for the heat of vaporization? Did you use the given final temperature for each of the three materials?(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))?In an insulated vessel, 239 g of ice at 0°C is added to 635 g of water at 15.0°C. (Assume the latent heat of fusion of the water is 3.33 x 10° J/kg and the specific heat is 4,186 J/kg · °C.) (a) What is the final temperature of the system? °C (b) How much ice remains when the system reaches equilibrium?
