A.
In a common classroom demonstration, a balloon is filled with air and submerged into liquid nitrogen. The balloon contracts as the gases within the balloon cool. Suppose the balloon initially contains 3.15 L of air at a temperature of 30.0 ∘C and a pressure of 0.991 atm .
Calculate the expected volume of the balloon upon cooling to -196 ∘C (the boiling point of liquid nitrogen).
B.
When the demonstration is carried out, the actual volume of the balloon decreases to 0.64 L . How well does the observed volume of the balloon compare to your calculated value?

Look at the spectrums of a star moving towards earth and a motionless star. which of these is a correct inference that can be draw from the observation of the two spectrums? (2 points) the spectrum of a motionless star is difficult to be viewed separately using oridinary telescopes. the spectrum of a motionless star is identical to the spectrum of a star which moves towards earth. the spectrum of a star shifts towards the red region when the star moves towards earth. the spectrum of a star shifts towards the blue region when the star moves towards earth.
