Answer:
centimeters 100 cubic centimeters
Step-by-step explanation:
The accompanying graph represents the theoretical relationship between the volume and the temperature of a gas under constant pressure: A volume versus temperature graph is shown with volume on the y axis from 0 to 900 cubic centimeters and temperature on the x axis from 0 to 100 Kelvin. A straight line connects 0, 0 to 80, 800.
First and foremost. We look for the slope then the equation of the line
slope=change in y/change in x

slope=800-0/(80-0)
slope=10
the equation of the line graph y=mx+C
C=intercept
m=slope/gradient
x=x axis
y=vertical axis
y=10x+c
c=0, because the line is on the origin
An increase in temperature from 20 Kelvin to 30 Kelvin produces an increase in volume of approximately ?
y=10x
x1=20K
X2=30K
Dy=10(30-20)
Dy=100
