Title: How many photons are needed to raise the temperature of a cup of water(250g) from 25 to 75 Celsius degrees?
Post by: imrubd on Sep 20, 2013
Water absorbs microwave radiation of wavelength of 3mm. How many photons are needed to raise the temperature from 25 to 75 celsius degrees in a microwave oven, using this radiation? The specific heat of water: 4.184j/g celsius.

The correct answer is: 7.9x10^26 photons.
Thank you for your help!
