A 1.5 m in diameter and 35 cm deep glass vessel is filled with ethyl alcohol. Heat is supplied at an average rate of 450 W/m2. Find the time required to raise the temperature of the ethyl alcohol from 25°C to 40°C if all the heat is absorbed by the ethyl alcohol. Assume there is no heat loss to surroundings.
