Physics Help?

1.) A person is served coffee before they drink it. In order that the coffee be hotest, should cream be added to it right away or just before it is drunk?

2.) Will a can of beverage cool just as fast in the regular part of the frigerator as it will in the freezer compartment? (I say "No", but im not quite sure.)

3.) If you wish to save fuel on a cold day, and you're going to leave your warm house for a half hour or so, should you turn your thermostat down a few degrees, down all the way, or leave it at room temperature?

Just before you drink it.

In freezer b/c it cools down faster.

Few degrees lower.
