Q2) A 100 MW power plant uses the lake water at 20°C to condense the steam in a boiler operating at 800°c. What will be the minimum heat that accumulates in the lake as a result of this process? This type of heat build-up is known as thermal pollution and can make water unsuitable for many aquatic organisms. Assume that this process is carried out in a lake containing 6.0 x 10° m water. If the heat capacity of water is 4.184 J / g K, calculate the increase in temperature in one day? If the limit temperature for living species is 50°C, how many months later will this plant begin to damage the lake?

operating at 800°c. What will be the minimum heat that accumulates in the lake as a result
of this process? This type of heat build-up is known as thermal pollution and can make water
unsuitable for many aquatic organisms. Assume that this process is carried out in a lake
containing 6.0 x 10° m water. If the heat capacity of water is 4.184 J / g K, calculate the
increase in temperature in one day? If the limit temperature for living species is 50°C, how
many months later will this plant begin to damage the lake?
