The specific heat capacity is 4.187 kJ/kg C for water, 2.108 kJ/kgC for ice, 1.996 kJ/kg C for steam. Water's specific latent heat is 3.4 x 105 J/kg for fusion and 2.3 x 10 J/kg for boiling. The speed of light is 3.00 x 10 m/s. 13. An average stove supplies 3.000 x 10* W of power (recall that 1W = 1J/s). How long would it take to bring 0.946 kg (4cups) of water from 18C to 100 C and then to convert it all to steam
