Question

URGENT.

Calculate the final pressure inside a scuba tank after it heats from 323 K to 523 K. The initial pressure in the tank is 45.0 atm.

If a gas is pressurized from 10.0 atm to 12.0 atm and the final temperature is at standard temperature (273.15 K), what was the initial temperature of gas?

Answer 1

1. 72.9 atm

2. 0.43937 K

Step-by-step explanation:

1. Gray- lussacs law is p1/t1=p2/t2 so we use this formula to figure it out by filling in the variables and solving

p1=45.0 atm

t1=323 K

p2= ?

t2=523 K

Now we fill in this in the formula and solve - 45.0 atm/ 323 K = p2/ 523 K

and now we solve for p2 by multiplying 535k by each side to give us p2

2. Using the same formula we get 10.0atm/? = 12.0 atm/ 273.15 k and we divide both sides by 10.0 atm
