A 56 kW electric furnace measures 1.2m x 1.3m x 0.7m. When the temperature inside the furnace is 1613 ºC, a block of aluminum with a mass of 283 kg and a temperature of 18 ºC is placed inside. Assuming the heat loss from the furnace walls is 529 W/m, how long (in min) will it take to heat the block to the furnace temperature? (Specific heat of aluminum is 0.90 kJ/kg. K)
A geyser heats water flowing at the rate of 3.0 litres per minute from 27 °C to 77 °C. If the geyser operates on a gas burner, what is the rate of consumption of the fuel if its heat of combustion is 4.0 × 104 J/g ?
If the specific heat of water is 4,186 J/kg∙°C, how much heat is required to increase the temperature of 1.2 kg of water from 23 °C to 39 °C?. Hint: To get the ΔT (Change in temperature), get the difference between final temperature (Tf) and initial temperature (Ti). [ΔT = Tf – Ti ]
