A find the amount of heat needed to raise the temperature, Ask an Expert

Academics

A) Find the amount of heat needed to raise the temperature of 6.3 kg of lead from -39^oC to 77^oC.

B) A 0.00340 kg lead bullet is traveling at 476 m/s when it hits the bull's-eye of a practice target. Half of the bullet's kinetic energy is transferred to the bullet in the form of heat. What is the resulting temperature increase in the bullet? Assume that the specific heat of the lead does not vary significantly over this temperature.
