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?

Listenbase your answer to the question on the information below.nuclear radiation is harmful to living cells, particularly to fast-growing cells, such as cancer cells and blood cells. an external beam of the radiation emitted from a radioisotope can be directed on a small area of a person to destroy cancer cells within the body.cobalt-60 is an artificially produced radioisotope that emits gamma rays and beta particles. one hospital keeps a 100.0-gram sample of cobalt-60 in an appropriate, secure storage container for future cancer treatment.which choice represents the correct product for the beta decay of the co-60? fe-60ni-60fe-61ni-61
