The microwaves are absorbed by the water molecules in the food, which is transferred to other components of the food. As the water becomes hotter, so does the food. Part A Suppose that the microwave radiation has a wavelength of 12.4 cm. How many photons are required to heat 295 mL of coffee from 25.0 °C to 62.0 °C? Assume that the coffee has the same density, 0.997 g/mL, and specific heat capacity, 4.184 J/(g - K), as water over this temperature range.

- Which statement about ozone and the ozonelayer is true?A. Ozone is found in a band of almost pureozone several kilometers thick encircling theEarth.B. The ozone in the ozone layer absorbs UVlight between 200 and 300 nm.C. Ozone is a compound with the chemicalformula CO2.D. In the Earth's atmosphere, ozone exists onlyin the ozone layer.E. Ozone is used as a coolant in refrigeratorsand air conditioners.Freon-12 (CF2Cl2), widely used as a refrigerant and aerosol propellant, is a dangerous airpollutant. In the troposphere, it traps heat 25 times as effectively as CO2, and in thestratosphere, it participates in the breakdown of ozone. Freon-12 is prepared industrially byreaction of gaseous carbon tetrachloride with hydrogen fluoride. Hydrogen chloride gasalso forms. How many grams of carbon tetrachloride are required for the production of16.0 dm3 of Freon-12 at 27°C and 1.20 atm?Which of the following is NOT a natural source of air pollution?
