The pressure in a bicycle tire is 66 psi at 50 ˚C in Phoenix. You take the bicycle up to Flagstaff, where the temperature is 32 ˚C. What is the pressure in the tire? (Volume and amount of moles are held constant)

Pressure in the tire is 62.32psi

Explanation:

The following were obtained from the question given:

P1 = 66 psi

T1 = 50˚C = 50 + 273 = 323K

T2 = 32˚C = 305K

P2 =?

Using P1/T1 =P2/T2 we simply calculate the new pressure as follows:

P1/T1 =P2/T2

66/323 = P2/305

Cross multiply to express in linear form

323 x P2 = 66 x 305

Divide both side by 323

P2 = (66 x 305) /323

P2 = 62.32psi

pressure in the tire is 62.32psi

answer: the primary difference between a hypothesis and a theory is that b hypothesis is falsifiable, but a theory has been proven to be correct. theory is an explanation of something that is happening but hypothesis is a guess of something that can happen

explanation:

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6
