Question

air is trasferred from 75 L tank where the pressure is 125 psi and the temperature is 288 K to a tire with a volume. of 6.1 L and a pressure of 25 psi. what is the new temperature ?

Answer 1

4.7K

Step-by-step explanation:

Given parameters:

Initial volume = 75L

Initial pressure = 125psi

to atm gives 8.5atm

Initial temperature = 288K

New volume = 6.1L

New pressure = 25psi

to atm gives 1.7atm

Unknown:

New temperature = ?

Solution:

To solve this problem, we use the combined gas law which is given below:

`(P1 V1)/(T1)` =
`(P2 V2)/(T2)`

P, V and T are pressure, volume and temperature

1 and 2 are initial and new states

`(8.5 x 75)/(288)` =
`(1.7 x 6.1)/(T2)`

T2 = 4.7K
