a) One way to cool a cup of coffee would be to plunge an
ice-cold piece of aluminum into it. Suppose a 20.00 g piece of
aluminum is stored in the refrigerator at 0.0oC and then dropped
into a cup of coffee. The coffee’s temperature drops from 90.0oC to
75oC. How many kJ of thermal energy did the piece of aluminum
absorb? (Specific heatAl = 0.902 J/g·oC.) 3b. Using information
from question #2 above, calculate the mass (g) of coffee...

Who do you think is responsible for the Cold War? Is there some
way the Cold War could have been prevented? Is there some way that
it could have been stopped?
Lizards are cold blooded. Rabbits are warm blooded. Both run on
chemistry, and the chemical reactions must be controlled. If the
reactions are too slow or fast, the animal will die. What factors
do you suppose that animals use to control the rate that these
biochemical reactions are occur?

a cold front and warm front. In addition, sketch, label, and
explain the setting for a stationary front.
Why would it be advantageous for hibernating animals to express
thermogenin in the mitochondria of specialized fat cells that
surround the arteries bringing blood to the brain?
