A 10 kg Iron Box is holding 48 kg of solid ice. Initially, both the box and the ice are at -35 C. The box is placed on an electric heater, which outputs 9580 J/s. Assume that all the energy produced by the heater goes into heating the box and the ice. The specific heat of iron is 450 J kg C, The specific heat of ice is 2108 J kg C, and the latent heat of fusion of ice is 333500 J kg. a) how much is energy is required to heat the box and ice to the melting point of ice (0 C)? [Show in Joules] b) How much energy (in Joules) is required to melt all the ice? c) How long does it take to melt all the ice from intial temp of -35 C? [Answer in minutes

In a thermodynamic process, pressure of a fixed mass of gas is changed in such a manner that the gas releases 20 joule of heat and 8 joule of work was done on the gas. If the initial internal energy of the gas was 30 joule, then the final internal energy will be:
You are considering two heaters in your house which must provide 10kW of heating. You expect to run it for 100 days per year, 16 hours per day. The first heater is gas and has an effiency of 40% but gas costs .01 cents per kWhr (kilowatt - hour) The electric heater is 82% efficient but the cost of electricity is .03 cents per kWhr Which is the cheaper option?
The intermal energy of a thermodynamic system decreases by 435 kJ. If at the same time, 164 kJ of work is done on the system, find the heat transfer. Answer:
If 200 J of heat is released by a reservoir at 373 K and absorbed by a second reservoir at 273 K, how much work capability is “lost” in this process? 200 J - 200 J 400 J 0
A Carnot heat pump is used to maintain the temperature inside a building at 20 ∘C. Significantly, the colder it gets outside, the more heat is lost through the walls and windows of the building. Assume that 45 kW of heat are lost for each degree difference between the outside and the inside temperature. That means that the colder it gets, the harder the heat pump will need to work. However, for safety reasons, the controller circuit for the heat pump limits its electrical power consumption to 195 kW. What's the coldest it can get outside before the heat pump can't maintain the building temperature adequately?
imagine a heat machine that operates between two thermal reservoir T1<T2 ,the machine does a work in quantity W,and it exchange heat in quantity Q1 and Q2 with its reservoirs.( Note: this heat machine dose not have to be a carnot machine , only requirement is that it must be cyclical).under this circumstances,if the work is positive,prove that Q2>0 and Q1>0.
A heat engine receives a heat-transfer at the rate of 2 MW at a high temperature of 750 °C. The engine releases energy to its surrounding at 300 K and work is produced at a rate of 1200 kW. What are 1. The energy released to the ambient surroundings? 2. The efficiency of the engine?
Using 1st and 2nd law of thermodynamics for irreversible expansion of Krypton: Krypton (ideal monatomic gas) is confined in one-fourth of a 48-litre container. The other part of the container is evacuated. When the partition is removed, the gas expands and fills the whole container, while the system loses 400J of heat to the environment at 290K. It is found that in the final state, the Krypton is at p2 = 5.5bar, T2 = 400K. Is this process possible or not? (?k?????? = 83.8 kg/kmol)
You are purchasing a refrigerator. You know that you want to keep your food at 1 deg C and that your house is typically at 19 deg C. What is the minimum power (kW) required to operate the refrigerator if the heat extracted is 297 kW?
A heat pump is used to heat a house during the winter. The house is to be maintained at 20 C at all times. When the ambient temperature outside drops to -10 C, the rate at which heat is lost from the house is estimated to be 25 kW. What is the minimum electrical power required to drive the heat pump?
Tec A solar hot-water-heating system consists of a hot-water tank and a solar panel. The tank is well insulated and has a time constant of 64 hr. The solar panel generates 1900 Btu/hr during the day, and the tank has a heat capacity of 3°F per thousand Btu. If the water in the tank is initially 112 F and the room ewd temperature outside the tank is 80°F, what will be the temperature in the tank after 11 hr of sunlight? After 11 hr of sunlight, the temperature in the tank will be about | PF. (Round to the nearest tenth as needed.) nts estl
A pressure cooker containing some water with an internal energy of 300 KJ isheated by a gas burner. 0.5 kg of steam with an enthalpy 1800 KJ/kg escapesthrough the safety valve. The average velocity of the steam is 5 m/s. The heat loss through the wall of the cooker is 250 KJ. If the final internal energy of the water and steam in the cooker is 500 KJ, find the heat supplied to the cooker.
