Water is boiled in a pan on a stove at sea level. During 10 min of boiling, it is observed that 200 g of water has evaporated. T
diamong [38]

Answer:

Rate of heat is 45.1 kJ/min

Explanation:

Heat required to evaporate the water is given by

Q = mL

here we know that

L = 2.25 \times 10^6 J/kg

now we have

Q = (0.200)(2.25 \times 10^6 J/kg)

Q = 452.1 kJ

now the power is defined as rate of energy

P = \frac{Q}{t}

P = \frac{452.1 kJ}{10}

P = 45.1 kJ/min
