Answer to Problem 44PPS
The required equation is
Explanation of Solution
Given information:
The given statement is that the volume of gas v varies inversely as the pressure p and directly as the temperature t .
The given relation is
The required equation is
b.
To write is the equation a direct, joint, inverse, or combined variation.
b.
Answer to Problem 44PPS
The equation is combined variation.
Explanation of Solution
Given information:
The equation of variation is
The standard form of the equation
There are three variables in the equation v , p and t . the equation is of
c.
To calculate the new pressure.
c.
Answer to Problem 44PPS
The new pressure is 1.82 atmospheres
Explanation of Solution
Given information:
Initial volume is 8 liters, initial temperature is 275 kelvin and initial pressure is 1.25 atmospheres. New volume is 6 liters new temperature is 300 kelvin.
Calculation:
For the initial values
Therefore,
The new pressure is 1.82 atmospheres
