In a physics lab, students are conducting an experiment to learn about the heat capacity of different materials. The first group is instructed to add a number of 1.50 g pellets made of lead, at a temperature of 92.0°C, to 305 g of water at 16.0°C. A second group is given the same number of 1.50 g pellets as the first group, but these are now aluminum pellets. Assume that no heat is lost to or gained from the surroundings for either group. (a) If the final equilibrium temperature of the lead pellets and water is 25.0°C, how many whole pellets did the first group use in the experiment? The specific heat of lead is 0.0305 kcal/(kg · °C). pellets (b) Will the final equilibrium temperature for the second group be higher, lower, or the same as for the first group? The specific heat of aluminum is 0.215 kcal/(kg · °C). O higher O lower O the same (c) What is the equilibrium temperature of the aluminum and water mixture for the second group? °C
Calculate the heat flow (H) into a refrigerator with a total outer surface area of 5.22m2, and given an outside temperature of 25°C and a fridge temperature of 8°C. The thickness of the walls of the fridge is 5.2 cm and they are insulated with polyurethane foam that has a thermal conductivity of 0.022 W/mk. 37.5W 55.3W 63.6W 77.2W
A 0.250-kg aluminum bowl holding 0.800 kg of soup at 26.6°C is placed in a freezer. What is the final temperature if 420 kJ of energy is transferred from the bowl and soup? Assume the soup has the same thermal properties as that of water, the specific heat of the liquid soup is 1.00 kcal/(kg · °C), frozen soup is 0.500 kcal/(kg · °C), and the latent heat of fusion is 79.8 kcal/kg. The specific heat of aluminum is 0.215 kcal/(kg · °C).
A chunk of metal has a mass of 600g and has been in boiling water for several minutes. It is quickly dropped into an insulating Styrofoam beaker containing 1.20 kg of water at room temperature (20.0°C). After waiting few minutes, you observe that the water's temperature has reached a constant value of 23.0 °C. The specific heat of water is 4190 J/(kgK). a) Assuming that the Styrofoam absorbs a negligibly small amount of heat and that no heat was lost to the surroundings, what is the specific heat of the metal? b) If the heat absorbed by the Styrofoam actually is not negligible, what would be the specific heat of the metal? A)Greater than the one calculated in part (a). B)Smaller than the one calculated in part (a). C)Same as the one calculated in part (a).
Suppose you walk into a sauna that has an ambient temperature of 52.0°C. (a) Calculate the rate of heat transfer in watts to you by radiation given your skin temperature is 37.0°C, the emissivity of skin is 0.98, and the surface area of your body is 1.40 m2. W (b) If all other forms of heat transfer are balanced (the net transfer is zero), at what rate will your body temperature increase in degrees Celsius per minute if your mass is 70 kg? °C/min
A dog loses a lot of heat by panting. The air rushing over the upper respiratory tract causes evaporation and thus heat loss. A dog typically pants pants at a rate of around 304 pants per minute. As a rough calculation, assume that one pant causes 0.0400 g of water to be evaporated from the respiratory tract. What is the rate of heat loss for the dog by panting? The heat of vaporization for water is 2256 kJ/kg.
