Problem 8.07**. (a) The number of kilocalories in food is determined by calorimetry tech- niques in which the food is burned and the amount of heat transfer is measured. How many kilocalories per gram are there in a 5.00-g peanut if the energy from burning it is transferred to 0.500 kg of water held in a 0.100 kg aluminum cup CA 900 kg K, causing a 54.9ºC temperature increase? [5.73 Cal/g] (b) Food labels indicate there are 828 Calories in 145 g (about a cup) of peanuts, is this consistent with your answer in the first part? =

A gas burner transfers 9.20 × 105 J into a block of ice with a mass of 2.29 kg and an initial temperature of 0°C. (a) How much of the energy (in J) supplied by the burner goes into melting all the ice into liquid water? (Enter you answer to at least three significant figures.) 769440 Melting is a phase change from solid to liquid and requires an energy transfer of Q = mLf where Li latent heat of fusion. Freezing is a phase change from liquid to solid and requires an energy transfer of Q = -mLf. In freezing, the energy transfer is negative because energy is removed from the substance. J (b) How much of the energy (in J) supplied by the burner goes into raising the temperature of the liquid water? (Er your answer to at least three significant figures.) 1.57E+5 X Think about conservation of energy. The total energy supplied is known, and you found in part (a) the energy t goes into melting. How much is left over? J (c) What is the final temperature of the liquid water in degrees Celsius?…

Over the course of a day, 4.0 kg of water evaporates from the leaves of a corn plant. a) How much energy is required to evaporate the water? (Assume that the temperature of the leaves is 30C.) b) If the plant is active for 12 hours, how much power does this correspond to? You can think of this as the necessary power to drive transport in the plant.
Six grams of liquid X at 35 degrees Celsius are added to 3 grams of liquid Y at 20 degrees Celsius. The specific heat of liquid X is 2 calories per gram per degrees Celsius, and the specific heat of liquid Y is 1 calorie per gram per degree Celsius. Now imagine that liquid X continues to transfer energy to liquid Y 12 calories at a time. How many total transfers would be required to reach a common temperature? 04 O more than S 02
