A 51-g ice cube at 0°C is heated until 43.0 g has become water at 100°C and 8.0 g has become steam at 100°C. How much energy was added to accomplish the transformation?  ?kJ

A 60.0-kg runner expends 359 W of power while running a marathon. Assuming 12.5% of the energy is delivered to the muscle tissue and that the excess energy is removed from the body by sweating, determine the volume of bodily fluid (assume it is water) lost per hour. (At 37.0°C the latent heat of vaporization of water is 2.41 ✕ 106 J/kg.) cm3

A jet of steam at 100°C is applied to a 2.00 kg block of ice at 0°C. How many grams of steam would be required to completely melt the ice assuming a complete transfer of thermal energy? nA d bloow olle boutaig erd 15000 lo yolla an ai e W lobin bna 1900 lo yolla ns e losbinom 4

How much energy is required to change a 30-g ice cube from ice at  −25°C  to steam at 115°C?  ?MJ

The initial temperature of 150 g of ice is -20°C. The spe-cific heat capacity of ice is 0.5 cal/g.C° and water's is1 cal/g•C°. The latent heat of fusion of water is 80 cal/g.a.How much heat is required to raisethe ice to 0°C andcompletely melt the ice?b. How much additional heat is required to heat the water(obtained by melting the ice) to 25°C?C.What is the total heat that must be added to convert the80 g of ice at-20°C to water at +25°C?d. Can we find this total heat simply by computing howmuch heat is required to melt the ice and adding theamount of heat required to raise the temperature of 80 gof water by 45°C? Explain

You are given 3.74 x 10 g of coffee (same specific heat as water) at 83.6°C. In order to cool this to 60.2°C, how much ice (at 0.0°C) must be added? Neglect heat content of the cup and heat exchanges with the surroundings. mice
