16 grams of ice at –32°c is to be changed to steam at 172°c. the entire process requires cal. round your answer to the nearest whole number. the specific heat of both ice and steam is 0.5 cal/g°c. the specific heat of water is 1.00 cal/gk. the heat of fusion is 80 cal/g and the heat of vaporization is 540 cal/g.

Glass is transparent to visibile light under normal conditions; however, at extremely high intensities, glass will absorb most of the light incident upon it. this works through a process known as multiphoton absorption. in this process, several photons are absorbed at the same time. if very intense light whose photons carry 2ev of energy is shined onto a material with a band gap of 4ev, that light can be absorbed through two-photon absorption, because two photons have the right amount of energy to bridge the band gap. what is the minimum number of photons of 800-nm light that are needed to equal or exceed the band gap of fused silica glass
