Question 1 (1 point) During an accident, (3.10x10"0i g of boiling water at 100.0C was splashed onto a burn victim's skin and cooled to 423C on the 370C skin How much tissue mass in grams. originally at 370C, was involved in cooling the water? Give your answer with three significant figures. Specific heat capacity of water is 4.186 J/(g-Kl. Specific heat of human tissue at 1.00 atm and 200C is 3.50 J/(g-K). Note: Your answer is assumed to be reduced to the highest power possible. Your Answer: Answer Question 2 (1 point) Acylinder contains (2.81x10'2) L of hydrogen gas (H2) at 00C and a pressure of 10.0 atm. How much energy in Joule is required to raise the temperature of this gas to 291C? Universal gas constant is 8.314J/(mol-K). For H2 ,C'V = 20.4 J/(mol-K). Provide your answer to three significant figures. Note: Your answer is assumed to be reduced to the highest power possible. Your Answer: Question 3 (1 point) Jill takes in 0.0140 mol of air in a single breath. The air is taken in at 200C and exhaled at 350C. Her respiration rate is (1.10x10"1) breaths per minute. At what average rate does heat leave her body due to the temperature increase of the air? Provide your answer to three significant figures. HINT: Use the molar specific heat at constant volume to find the heat loss, where Cu = 51372 (for an ideal diatomic gas). Note: Your answer is assumed to be reduced to the highest power possible. Your Answer: Answer Question 4 (1 point) An (6.67x10"1)-kg man eats a banana of energy content 451 id (108 kcal). If all of the energy from the banana is converted into kinetic energy of the man, how fast is he moving (in SI units). assuming he starts from rest? Provide your answer with three significant figures. Note: Your answer is assumed to be reduced to the highest power possible. Your Answer: Question 5 (1 point} A (8.10x10A1lkg block of ice at 000C breaks off from a glacier. slides along the frictionless ice to the ground from a height of 2.43 m, and then slides along a horizontal surface consisting of gravel and dirt. Find how much in grams of the mass of the ice is melted by the friction with the rough surface, assuming 75.0% of the internal energy generated stays in the ice. Latent heat of fusion (if) for water 333,700 J/kg. Provide your answer to three significant figures. Note: Your answer is assumed to be reduced to the highest power possible. YourAnswer: Answer Question 6 (1 point} How much internal energy in Joule is generated when a (6.4000x10'0ig lead bullet, traveling at (6.00x10"2) mz's, comes to a stop as it strikes a metal plate? Give your answer with three significant figures. Note: Your answer is assumed to be reduced to the highest power possible. Your
