Owls have good night vision because their eyes can detect a light intensity as low as 5.0 x 10^(-13) W/m^2. Calculate the number of photons per second that an owl’s eye can detect if its pupil has a diameter of 9.0 mm and the light has a wavelength of 500 nm. (1W = 1J/s.)

Melting and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.
