If two such bars were placed in series (end to end) between the same constant-temperature baths, what would the rate of heat conduction P be? W A copper bar of thermal conductivity 401 W/(mK) has one end at 116C and the other end at 24.0C. The length of the bar is 0.160 m, and the cross-sectional area is 1.00 106 m2. What is the rate of heat conduction P along the bar? Small animals eat much more food per kilogram of body mass than do larger animals. The basal metabolic rate (BMR) is the minimal energy intake necessary to sustain life in a state of complete inactivity. The table lists the BMR in kilocalories per day, the mass, and the surface area for 4 animals. Animal BMR (kcal/d) Mass (kg) Surface Area (m2) Mouse 3.80 0.0270 0.00120 Dog 770.0 15.3 0.710 Human 2050 62.0 2.00 Horse 4900 388 6.20 What is the BMR per square meter of the surface area for the mouse? kcal/d/m2 A lizard of mass 7.30 g is warming itself in the bright sunlight. It casts a shadow of 1.60 cm2 on a piece of paper held perpendicularly to the Sun's rays. The intensity of sunlight at the top of the Earth's atmosphere is 1.40 103 W/m2, but only half of this energy penetrates the atmosphere and is absorbed by the lizard. The lizard has a specific heat of 4.20 J/(gC). Assuming that there is no heat loss by the lizard (to simplify), how long must the lizard lie in the Sun in order to raise its temperature by 1.40C? min Tina is going to make iced tea by first brewing hot tea, then adding ice until the tea cools. Ice, at a temperature of 10.0C, should be added to a 2.50 104 m3 glass of tea at 95.0C to cool the tea to 10.0C. The glass has a mass of 0.350 kg and the specific heat of the glass is 0.837 kJ/(kgK). Specific heat capacity (15.0C) of water is 4.186 kJ/(kgK) and heat of fusion of water is 333.7 kJ/kg. Specific heat capacity of ice is 2.10 kJ/(kgK). Find the mass of the ice required to cool the tea to 10.0C, without ignoring the temperature change of the glass. g The average body temperature of a healthy person is 37.0C. Boltzmann's constant is 1.38 1023 J/K. What is the average kinetic energy of the gas molecules in the lungs? J Please help me
