Pre-Lecture Question 05 To answer this question, first click here to view the assoclated videa. In light sources that utilize electrical gas discharge, like in neon signs, the emitted light is composed of discrete colors rather than the full spectrum (such as in sunlight). Even though the gas discharge source emits multiple colors of light, your eyes can only detect one color. If the light from a gas discharge source is passed through a prism, what will you see?
a. A series of individual colors located where they would otherwise be in the full spectrum (but the other colors in the spectrum are missing)
b. A continuous spectrum, the same as for sunlight.
c. Only one color: the one that your eyes detect emitted from the source

The magnitude of the amount of energy released by burning a fuel source, measured in energy per unit mass, is called its fuel value. note that the fuel value is the negative of the isobaric specific heat of combustion for the fuel. if all the energy obtained from burning 1.23 pounds of butane with a fuel value of 10.85 kcal/g is used to heat 128.0 kg of water at an initial temperature of 18.3 Β°c, what is the final temperature? note that 1 lb = 453.6 g.
