Repeat Prob. 1016 for a copper heating element. Data from problem 16 Water is boiled at sea

Question:

Repeat Prob. 10–16 for a copper heating element.

Data from problem 16

Water is boiled at sea level in a coffee maker equipped with a 20-cm-long 0.4-cm-diameter immersion-type electric heating element made of mechanically polished stainless steel. The coffee maker initially contains 1 L of water at 14°C. Once boiling starts, it is observed that half of the water in the coffee maker evaporates in 25 min. Determine the power rating of the electric heating element immersed in water and the surface temperature of the heating element. Also determine how long it will take for this heater to raise the temperature of 1 L of cold water from 14°C to the boiling temperature.
