K, what is the rate of heat transfer (in W) from the plate to the air [round your final answer to zero decimal places]? T. S Air, T, 00

How much thermal energy (in J) is required to boil 2.45 kg of water at 100.0°C into steam at 135.0°C? The latent heat of vaporization of water is 2.26 ✕ 106 J/kg and the specific heat of steam is  2010  J kg · °C . HINT  J

A 500 g copper cup has an initial temperature of 250 oK. If the specific heat of copper is 385 J kg-1 oK-1 and 2.5 x 104 J of heat are transferred into it, what is the final temperature of the cup in Kelvins?

153 kilojoules [kJ] of energy are expended lifting a pile of bricks 50 feet [ft] into the air.  If each brick weighs 5 pounds-force [lbf] and has dimensions of 8 inches [in] x 2.25 inches [in] x 4 inches [in], calculate the number of bricks lifted.  Round your answer to the nearest whole number of bricks.

Ice at 0.0°C is mixed with 6.30 × 102 mL of water at 25.0°C. How much ice must melt to lower the water temperature to 0.0°C? The specific heat capacity of water is 4.186 J/(g·K). Latent heat of fusion for water is 333.7 J/g.

There is a .32 kg block of silver that is 21 °C. If silver's melting point is 961°C, how much thermal energy would a scientist need to melt this block of silver? (Hf = 111 kJ/kg). Hf is the heat of fusion of silver! Solve, assuming that the specific heat of silver is .24 J/g*degC, or 235 J/kg*K.

A 26 grams silver ring (specific heat capacity: 234 J/Kg C)  is  heated to a temperature of 83.7 C and then placed in a calorimeter containing 0.05 Kg of water at 23.8 C. The calorimeter is not perfectly insulated, however, and 0.14 kJ of energy is transferred to the surroundings before a final temperature is reached. What is the final temperature?

During a marathon race David uses energy at a rate of 292 W. What volume of body fluid does he lose in the 5.5 hours of the race if 17.0% of the energy goes to the muscle tissue and the rest is used in removing the perspiration from the body. The latent heat of vaporization is 2.41*10^6 J/kg at 37.0°C and density of water is 1000 kg/m3. Answer in cubic meters.
