How much time (in seconds) is needed for a surgical cauterizer to raise the temperature of 2.00 g of tissue from 37.0°C to 100°C and then boil away 0.200 g of water, if it puts out 1.50 mA at 20.0 kV? Ignore heat transfer to the surroundings. (Assume the specific heat of tissue is 3,500 J/(kg · °C) and the latent heat of vaporization of water is 2,256 kJ/kg.)

Q3. A cube with side lengths of 2.91 cm is heated to a constant temperature of 720 ◦C at the focal point inside of a parabolic reflector. This has the effect of directing all of the cube’s radiant energy toward a 3.92 kg pack of ice that is initially at −19.0 ◦C. If the emissivity of the cube is 0.466, how long does it take for the ice to completely vaporize? Use the following numbers in your calculation: • The...
