Question

for a fixed mass of a gas and constant pressure, which of the following graphs are related to $V\propto$ T, the Charle's law?

(a)

(b)

(c)

(d)

• A. b,c,d
• B. a,b,c
• C. a,c,d
• D. a,b,d

Answer 1

The correct option is C a,c,d

Charle's law suggests that the graph between V vs T would be a straight line. This line would pass through the origin if the x-axis has temperature in Kelvin. If the temperature is in degree Celsius, the line cuts the x-axis behind the origin - i.e. -273.15 degree celsius.

Also, V/T is a constant and would cause a straight line to be formed if V/T is plotted against T.
