the graph shows the volume of a gas sample changes as the temperature changes and the pressure remains constant. which of these best represents the rate of change in the volume of the gas sample with respect to the temperature

The answer is 1/12 mL/c

Step-by-step explanation:

you rise over run and you get 5/60 which simplify to 1/12 .  

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
