5) Consider a thermal system consisting of 50 g of ice at -25°C and 0.2 kg of water at 15°C. a) What is the final temperature if these two systems are brought together and allowed to thermally interact. These systems are insulated from the rest of the environment. Don't forget the heat of fusion for water. Data: Cice=2220 J/(kg.K) L=333 kJ/kg, Cwater=4190 J/(kg.K) Part b) is on area and volume coefficient of expansion: b) Show that if every dimension of a metal follows the law of the linear expansion a show that the areal coefficient of expansion is 20 and that of the volume is 3c. Note Look up coefficient of linear expansion values for materials and note it is very small. Your derivation must take this fact into account.

A high-end gas stove usually has at least one burner rated at 14 000 Btu/h. (a) If you place a 0.25-kg aluminum pot containing 2.0 liters of water at 20.C on this burner, how long will it take to bring the water to a boil, assuming all the heat from the burner goes into the pot? (b) Once boiling begins how much time is required to boil all the water out of the pot?
What mass of water at 25.0C must be allowed to conic to thermal equilibrium with a 1.85-kg cube of aluminum initially at 1.50 102C to lower the temperature of the aluminum to 65.0C? Assume any water turned to steam subsequently recondenses.

Suppose a person is covered head to foot by wool clothing with average thickness of 2.00 cm and is transferring energy by conduction through the clothing at the rate of 50.0 W. What is the temperature difference across the clothing, given the surface area is 1.40 m2?
Describe a situation in which heat transfer occurs. What are the resulting forms of energy?
A steam pipe is covered with 1.50-cm-thick insulating material of thermal conductivity 0.200 cal/cm C s. How much energy is lost every second when the steam is at 200.C and the surrounding air is at 20.0C? The pipe has a circumference of 800. cm and a length of 50.0 m. Neglect losses through the ends of the pipe.
Most automobiles have a coolant reservoir to catch radiator fluid than may overflow when 1he engine is hot. A radiator is made of copper and is filled to its 16.0L capacity when at 10.0C. What volume of radiator fluid will overflow when the radiator and fluid reach their 95.0C operating temperature, given that the fluid’s volume coefficient of expansion is =400106/C ? Note that this coefficient is approximate, because most car radiators have operating temperatures of greater than 95.0C.
In 1993, the U.S. government instituted a requirement that all room air conditioners sold in the United States must have an energy efficiency ratio (EER) of 10 or higher. The EER is defined as the ratio of the cooling capacity of the air conditioner, measured in British thermal units per hour, or Btu/h, to its electrical power requirement in watts. (a) Convert the EER of 10.0 to dimensionless form, using the conversion 1 Btu = 1 055 J. (b) What is the appropriate name for this dimensionless quantity? (c) In the 1970s, it was common to find room air conditioners with EERs of 5 or lower. State how the operating costs compare for 10 000-Btu/h air conditioners with EERs of 5.00 and 10.0. Assume each air conditioner operates for 1 500 h during the summer in a city where electricity costs 17.0 per kWh.
In a showdown on the streets of Laredo, the good guy drops a 5.00-g silver bullet at a temperature of 20.0C into a 100-cm3 cup of water at 90.0C. Simultaneously, the bad guy drops a 5.00-g copper bullet at the same initial temperature into an identical cup of water. Which one ends the showdown with the coolest cup of water in the West? Neglect any energy transfer into or away from the container.
Answer the following by filling the blank: During a bout with the flu, an 80-kg person ran a fever of 39 oC. Consider that the specific heat of any human body is 3470 J/kg K, how much energy does the body need to burn to reach the fever temperature? The answer (in fundamental SI unit) is ___________ (type the numeric value only, dont use scientific notation)
(II) Determine the latent heat of fusion of mercury usingthe following calorimeter data: 1.00 kg of solid Hg at itsmelting point of -–39.0°C is placed in a 0.620-kg aluminumcalorimeter with 0.400 kg of water at 12.80°C; the resultingequilibrium temperature is 5.06°C
Even when shut down after a period of normal use, a large commercial nuclear reactor transfers thermal energy at the rate of 150 MW by the radioactive decay of fission products. This heat transfer causes a rapid increase in temperature if the cooling system fails.(1 watt = 1 joule/second or 1 W = 1 J/s and 1 MW = 1 megawatt)(a) Calculate the rate of temperature increase in degreesCelsius per second (ºC/s) if the mass of the reactor core is 1.60×105 kg and it has an average specific heat of 0.3349 kJ/kgº ⋅ C . (b) How long would it take to obtain a temperature increase of 2000ºC , which could cause some metals holding the radioactive materials to melt? (The initial rate of temperature increase would be greater than thatcalculated here because the heat transfer is concentrated in a smaller mass. Later, however, the temperature increase would slow down because the 5×105-kg steel containment vessel would also begin to heat up.)
