1. A 250. mL sample of gas has a temperature of 24.5^oC and a pressure of 0.99 atm. What temperature would be needed for the same amount of gas to fit into a 500. mL flask at standard pressure? (Amount of moles is held constant)
 2. The pressure in a bicycle tire is 35.5 psi at 32.5^o C in Phoenix. You take the bicycle up to Flagstaff, where the temperature is 21.1 C. What is the pressure in the tire? (Volume and Amount of moles is held constant)

58750.08068 is the answer i think

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
