The battery in a laptop computer supplies 111 v and has a capacity of 48 wh. suppose that the laptop is placed in an insulating briefcase with a fully charged battery, but it does not go into "sleep" mode, and the battery discharges as if the laptop were in use. if no heat leaves the briefcase, the heat capacity of the briefcase itself is negligible, and the laptop has a mass of 2.3 kg and an average specific heat of 0.8 kj kg- c-estimate the temperature of the laptop after the battery has fully discharged. assume that the computer started off at a cool 20°c. the temperature of the laptop after the battery has fully discharged is 'c.

The heat released from fission reactions is used to change water into steam. The steam then turns the blades of a turbine to generate energy. The answer will hence be B. Quickly moving neutron coming out of the reaction are slowed down by water. The water heats up and turns into steam. The steam turns the turbine and produces electricity.
