According to the Combined Gas Law, the volume of a gas varies inversely as the pressure and directly as the temperature. When a certain gas occupies a volume of
2.4L at 25°C, the pressure of the gas is 720 mmHg?

a.
Define variables and write a combined variation equation
to represent the situation.

b. CALCULATE PRECISELY Suppose the volume of the gas is reduced to a volume of
2 L and the temperature is increased to 28°C. What is the pressure of the gas?
Show your work.

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

whatvare the choices
