31. When 9.42 g of methane (CH4) is burned in a bomb calorimeter (heat capacity = 2.677 × 103 J/°C), the temperature rises from 24.00 to 27.08°C. How much heat is absorbed by the calorimeter? CH4(g) + 2O2(g) → CO2(g) + 2H2O(l); ΔH° = –1283.8 kJ a. 745 kJ b. 4.84 × 103 kJ c. 8.24 kJ d. 753 kJ e. 1.28 × 103 kJ 32. Which of the following statements is incorrect concerning the wave function? The wave function...

When you jog, most of the food energy you burn above your basal metabolic rate (BMR) ends up as internal energy that would raise your body temperature if it were not eliminated. The evaporation of perspiration is the primary mechanism for eliminating this energy. Determine the amount of water you lose to evaporation when running for 46 minutes at a rate that uses 400 kcal/h above your BMR. (That amount is often considered to be the "maximum fat-burning" energy output....

Two neighbors, Mr. Jones and Mr. Rogers, each have identical swimming pools (same size, same amount of water, etc.). One day, Mr. Jones heats his pool using a highly efficient solar panel from T-18°C to T=21°C. That same day Mr. Rogers uses an old, inefficient natural gas heater to heat his pool from T-20 C to T-23 C. Mr. Jones brags to Mr. Rogers that since the solar panel is more efficient than the mechanical heater, he has added less...

25. When calculating price elasticity of supply, you notice that a 2% change in price results in a 4% change in quantity supplied. Calculate the quotient and comment on the price elasticity of supply. (2 or more paragraphs) Chapter 6 26. The inquisitive student in 6th grade has asked you to explain the concept of diminishing marginal utility using normal-sized (1.74 ounces) (Gillette College vending machines) bags of peanut M&Ms. How will you explain this concept to the gifted student...

The first law of thermodynamics In thermal physics, we are often interested in the internal energy (E) of a system. The wo 41 internal energy of an ideal gas is proportional to the temperature and the number of moles of the gas. The internal energy can change when energy is exchanged with the system's environment (ie., objects that are outside the system of interest). The case above is one in which the internal energy of a gas changes due to...
