An aluminum tea kettle of 0.45-kg containing 2.40-kg of water at
25°C is placed on a
burner. Assuming that the burner is rated at 2000 Watt, how long
will it take to bring
the water to a boil? (b) Once boiling begins, how much time is
required to boil all the
water out of the tea kettle? Assume that no energy is lost in this
process.

Pleases help me thanks.
5 kg of liquid water at 100°C was converted to steam at 100°C by boiling at standard atmospheric pressure, in the arrangement of the figure below. The volume of the water changed from an initial value of 0.005 mº as a liquid to 8.355 mº as steam. Latent heat of vaporization for water Lv = 2256 kJ/kg. Standard atmospheric pressure is 1 atm or 1.01 x 109 Pa. Loaded Piston Steam Insulation Insulation Liquid water Thermal...
