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.)
