Suppose 9.30 x 105J of energy are transferred to 2.00 kg of ice at 0°C. What is the energy required to melt all the ice into liquid water

The rate at which a resting person converts food energy is called one’s basal metabolic rate (BMR). Assume that the resulting internal energy leaves a person’s body by radiation and convection of dry air. When you jog, most of the food energy you burn above your BMR becomes internalenergy that would raise your body temperature if it were not eliminated. Assume that evaporation of perspiration is the mechanism for eliminating this energy. Suppose a person is jogging for “maximum fat burning,” converting food energy at the rate 400 kcal/h above his BMR, and putting out energy by work at the rate 60.0 W. Assume that the heat of evaporation of water at body temperature is equal to its heat of vaporization at 100°C. (a) Determine the hourly rate at which water must evaporate from his skin. (b) When you metabolize fat, the hydrogen atoms in the fat molecule are transferred to oxygen to form water. Assume that metabolism of 1.00 g of fat generates 9.00 kcal of energy and produces 1.00 g of…

The total internal kinetic energy of 5 gallons of water is 2x10^8 J. The total kinetic internal energy of the water in a 100,000 gallon swimming pool is 5x10^11J. How many water molecules are in the 5 gallon water? Which body of water is at higher temperature?

A 26 gram of copper pellets are removed from a 300 degree C oven and dropped into 110 ml of water at 20 degrees C. What will the new water temp be in C?  C water=4200 J/kg/K C copper= 390 J/kgk
