The 1995 Nobel Prize in Chemistry was shared by Paul Crutzen, F. Sherwood Rowland, and Mario Molina for their work! concerning the formation and decomposition of ozone in the stratosphere. Rowland and Molina hypothesized that chlorofluorocarbons (CFCs) in the stratosphere break down upon exposure to UV radiation, producing chlorine atoms. Chlorine was previously...

1. What effects can heat transfer have on H2O, if no
chemical reactions occur?
a) At 0°C, the
temperature of the water in an ice-water mix may increase, or the
temperature of the ice in the ice-water mix may decrease.
b) Either the
temperature of the water will change or the phase will change, but
not both at the same time.
c) At 0°C, ice will
expand as it turns into liquid water.
d) None of the
above.

Using Microwave Radiation to Heat Coffee (expanded) Microwave ovens use microwave radiation to heat food. 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 215 mL of coffee from 25.0 ∘C to 64.6 ∘C? The coffee has a density...
