You recently bought an aluminum (C = 0.9 J/g-K) kettle with a mass of 2 kg. You used the kettle to heat water (C = 4.184 J/g-K). The kettle contains water (1.5 kg). The kettle was heated using an induction stove from 20°C to 85°C. The water is then used for coffee. If no heat is lost to the surroundings, what is the total heat added to raise the temperature?

A 10 kg box is hit by a truck and slides across the concrete. After being hit by the truck the box has an initial velocity of 6m/s and takes 5m to come to a stop. If the box heats up by 10 degrees, what are the specific heat of the box and the coefficient of friction between the box and the concrete?

J Submit Answer How much heat energy is required to evaporate 625 g of water which is initially at a temperature of 43 °C? J

0.863). It has a temperature of 67.0 °C. The new owner of the house paints the radiator a lighter color In an old house, the heating system uses radiators, which are hollow metal devices through which hot water or steam circulates. In one room the radiator has a dark color (emissitivity (emissitivity = 0.471). Assuming that it emits the same radiant power as it did before being painted, what is the temperature (in degrees Celsius) of the newly painted radiator? Tafter Tbefore After painting Original color Units Number

If 31.0 g of milk at a temperature of 3.95°C is added to a 250-g cup of coffee at a temperature 88.5°C, what is the final temperature of the mixture? Assume coffee has a specific heat of 4.19 x 10° 1/(kg · K) and milk has a specific heat of 3.93 x 103 1/(kg · K). °C

A rectangular window in a home has a length of 1.5 m and a height of 0.80 m. If the window allows heat to escape from the  home at a rate of 2,000 watts, how thick must the window be if the inside temperature of the home is 220 C and the outside temperature is 3.00C? (Assume that the coefficient of thermal conduction of glass is 0.80 W/mK.)   a. 7.1 mm   b. 124 mm   c. 9.1 mm   d. 8.1 mm   e. 11 mm

A block of ice (m = 11 kg) at a temperature of T1 = 0 degrees C is placed out in the sun until it melts, and the temperature of the resulting water rises to T2 = 23 degrees C. Recall that the specific heat of water is c = 4186 J/(kg⋅K), and its latent heat of fusion is Lf = 3.34 × 105 J/kg. A:  Input an expression for the amount of energy, Em, needed to melt the ice into water. B: Input an expression for the total amount of energy, Etot, to melt the ice and then bring the water to T2. C: What is this energy in joules?

A 0.867 kg sample of ethanol is in its liquid state at its boiling temperature of 78 C. If 1.93e5 J of energy are transferred into the sample, what percentage of the sample is vaporized? ethanol has: a specific heat of 1000 J/kgK in solid form, a specific heat of 2010 J/kgK in liquid form, a freezing temperature of –114 C a boiling temperature of 78 C, a latent heat of fusion of 1.05e5 J/kg, and a latent heat of vaporization of 8.54e5 J/kg
