In an experiment, a heated cup of coffee is removed from a heat source, and the cup of coffee is then left in a room that is kept at a constant temperature. The graph above shows the temperature, in degrees Fahrenheit (.^@F) , of the coffee immediately after being removed from the heat source and at 10-minute intervals thereafter. Of the following, which best approximates the temperature, in degrees Fahrenheit, of the coffee when it is first removed from the heat source?

Explain why non ideal solutions deviate from Raoult's law.

An inductor is connected to a battery through a switch. Explain why the emf induced in the inductor is much larger when the swithc is opened as compared to the emf induced when the switch is closed.
