Which statement is a description of charles’s law?
a)the temperature and volume of a gas are directly proportional when pressure is constant.
b.)the temperature and volume of a gas are inversely proportional when pressure is constant.
c.)the volume and pressure of a gas are directly proportional when temperature is constant.
d.)the volume and pressure of a gas are inversely proportional when temperature is constant.

At constant P, the temperature and volume of a gas are directly proportional.      

Explanation:

According to Charles's law " At constant pressure, the temperature and the volume of a gas are directly proportional to each other ". The mathematical description for Charles's law is given by :

At constant P,

i.e.

or V = k T

k = constant

Hence, the correct option is (A) " The temperature and volume of a gas are directly proportional when pressure is constant ".  

b

explanation:

bc its just b
