the surface of the sun is at a temperature of about 5800 K. suppose that the sun were the same size, but it had a temperature of 7000 K instead of 5800 K. use the graph of Planck's law to predict the ways that the sun's light would be different.

High-pressure liquid chromatography (hplc) is a method used in chemistry and biochemistry to purify chemical substances. the pressures used in this procedure range from around 500 kilopascals (500,000 pa) to about 60,000 kpa (60,000,000 pa). it is often convenient to know the pressure in torr. if an hplc procedure is running at a pressure of 1.03×108 pa , what is its running pressure in torr?
