Photons absorbed in matter are converted to heat. A source emitting n

1.	Photons absorbed in matter are converted to heat. A source emitting n photon/sec of frequency ν is used to convert 1kg of ice at 0°C to water at 0°C. Then, the time T taken for the conversion (a) decreases with increasing n, with ν fixed. (b) decreases with n fixed, ν increasing (c) remains constant with n and ν changing such that nν = constant. (d) increases when the product nν increases.
Answer» (a), (b), (c) (a) decreases with increasing n, with ν fixed. (b) decreases with n fixed, ν increasing (c) remains constant with n and ν changing such that nν = constant.
