Answer:
The difference is 
Step-by-step explanation:
We must find the common denominator of the fractions.
The common denominator of 
and 
is 
; therefore we have
now it is easy to subtract 
using the number line: we have to move units to the left in order to get to 
.
Thus our answer is
The answer is 7 because f is a denomination
Answer:
100 psia
Step-by-step explanation:
Applying,
Pressure law,
P/T = P'/T'................. Equation 1
Where P = initial pressure, P' = Final pressure, T = initial temperature, P' = Final temperature.
make P' the subject of the equation
P' = PT'/T............ Equation 2
From the question,
Given: P = 50 psia, T = 300°R = (300×5/9)K = 166.66 K, T' = 600°R = (600×5/9)K = 333.33 K
Substitute these values into equation 2
P' = (50×333.33)/166.66
P' ≈ 100 psia
P ≈ 100 psia
