CHCII A photovoltaic cell converts light into electrical energy. Suppose a certain photovoltaic cell is only 73.6% efficient, in other words, that 73.6% of the light energy is ultimately recovered. If the energy output of this cell is used to heat water, how many 633nm photons must be absorbed by the photovoltaic cell in order to heat 4500.0 g of water from 0.0°C to 214°C?
. A photovoltaic cell converts light into electrical energy. Suppose a certain photovoltaic cell is only 61.2 % efficient, in other words, that 61.2 % of the light energy is ultimately recovered. If the energy output of this cell is used to heat water, how many 575 nm photons must be absorbed by the photovoltaic cell in order to heat 450.0 g of water from 0.0°C to 214°C?

d. (4 Points)A photovoltaic cell converts light into electrical energy. Suppose a certain photovoltaic cell is only 43.5% efficient, in other words, that 43.5% of the light energy is ultimately recovered. If the energy output of this cell is used to heat water, how many 512 nm photons must be absorbed by the photovoltaic cell in order to heat 10.0 g of water from 20.0°C to 30.0°? 07 The specific heat of water is 4.184 J/g-"C.
