Question

he Volume in an experiment is changed (in mL) is 200, 100, 50, 25, 12.5 and we measured the pressure (in atm) is 0.1000, 0.2000, 0.4000, 0.8000, 1.6000 then the slope of the graph will be... (Hint: You may want to draw it out first. Keep the numbers in order when you create your data table.)

Answer 1

Answer: Slope = - 1000.

Explanation:

The line of best fit of the graph will be linear.

The general linear equation can be expressed as;

Y = MX + C

Where the Y variable represents the volume in the experiment as dependent variable and the X represent the pressure as independent variable.

The equation can be rewritten as:

V = MP + C

Where C is the intercept.

Given that

V = 200, 100, 50, 25, 12.5 and

Pressure P = 0.1000, 0.2000, 0.4000, 0.8000, 1.6000

The slope M can be calculated by using the formula

M = (V2 - V1)/ (P2 - P1)

Where V1 = 200, V2 = 100, P1 = 0.1, P2 = 0.2

Substitute all the parameters into the formula

M =( 100 - 200)/ ( 0.2 - 0.1 )

M = -100/0.1

Slope M = - 1000
