Heat transfer is required to raise the temperature of a 0.699 kg aluminum pot containing 2.77 kg of water from 32.5ºc to the boiling point and then boil away 0.695 kg of water. if the rate of heat transfer is 292 w, how long does this process take? aluminum's specific heat is 0.215 kcal/kgºc; water's specific heat is 1.00 kcal/kgºc; and heat of vaporization for water is 539 kcal/kg.

Cyclotrons are widely used in nuclear medicine for producing short-lived radioactive isotopes. these cyclotrons typically accelerate h- (the hydride ion, which has one proton and two electrons) to an energy of 5 mev to 20 mev. this ion has a mass very close to that of a proton because the electron mass is negligible—about 1 2000 of the proton’s mass. a typical magnetic field in such cyclotrons is 1.9 t. (a) what is the speed of a 5.0-mev h-? (b) if the h- has energy 5.0 mev and b = 1.9 t, what is the radius of this ion’s circular orbit?
