A 0.5m2 solar collector collects radiation from the sun and focuses it on 250g of
water that is initially at 23°C. The average intensity of radiation arriving from the
sun at this location is 550Wm-2. If you assume that this is collected with 100%
efficiency. How much time is required for the collector to raise this temperature
to boiling, at 100°

known's and unknown's:
m = 2.25 kg
Ti = 23 C
Tf = 100 C
Efficiency = 100%
Average intensity = 550Wm^-2
