In open wide pot exists a certain amount of water, which has mass m=6,5 kg, which free surface has S=960 cm^2. When this amount of water is exposed to Sun, then its temperature gets higher by deltaT=10 K for time t=30 mins. What is the temperature of Sun?
Sun radiates as absolute black body and that surface of the pot is perpendicular to the sun rays. Absorption of atmosphere of Sun and Earth overrule.
The Attempt at a Solution
Problem here is that I am bit confused. Is something missing in this problem? Like some variables? How could I calculate the energy that water received without C(constant of thermal conduction)
Just need a little push here.
