An energy input of 33.44kj is required to raise the temperature of 100 grams of water from room temperature (20°c) to boiling temperature (100°c). how many photons of energy are needed to bring 250 grams of room temperature water to boiling if 288 mili-meter electro-magnetic radiation is used to heat the water?

What would occur if the index of refraction of a material was less than n=1? the speed of light would increase to a speed larger than the maximum speed of light in a vacuum. the light wave would not bend at all though the material. the light wave would not be able to refract and would instead reflect off of the material. the speed of light would reduce to values close to 0 m/s.
