- How much thermal energy (in J) is required to boil 1.90 kg of water at 100.0°C into steam at 157.0°C? The latent heat of vaporization of water is 2.26 x 10° J/kg and the specific heat of steam is 2010 kg · °C HINTAn aluminum cup with mass 0.34 kg holds 0.36 kg of water. Both the cup and the water have a temperature of 12.°C. If a 0.13-kg piece of copper at 62.°C is added to the cup, what is the final equilibrium temperature in °C? You may assume that the cup, water, and copper are well insulated from anything else.Heat transfers by conduction through a glass window, connecting a 22 degree Celsius room to a 36 degree Celsius summer day outside. If the area of the window is 0.75 m^2, the thickness of the glass is 0.5 cm, and the thermal conductivity of glass is 1.0 J/s m K, how much heat transfers through the window of each second?
