Question

The graph shows a relationship between volume and temperature. Which of the following statements is true?

A.) The graph shows a directly proportional relationship between volume and temperature and represents Charles' Law.
B.) The graph shows an indirectly proportional relationship between volume and temperature and represents Boyle's Law.
C.) The graph shows an indirectly proportional relationship between volume and temperature and represents Gay-Lussac's Law.
4.) The graph indicates that when temperature is increased, volume decreases.​

Answer 1

The graph shows a directly proportional relationship between volume and temperature and represents Charles' Law.

Step-by-step explanation:

The relation between volume and temperature is given by :

Ideal gas law, PV = nRT

Where

P is pressure

V is volume

R is gas constant

T is temperature

As volume and temperature have direct relationship. Charles law states that there is a direct relationship between volume and temperature. The correct option is (a).
