Held constant, the pressure and volume of gas . its from boyle's law

Answer : When temperature is held constant, the pressure and volume of gas are inversely proportional.

Explanation :

Boyle's law : It is defined as at constant temperature and amount of gas remains unchanged, the pressure of the gas is inversely proportional to the volume of the gas.

Using ideal gas law equation :

where,

P = pressure of the gas

V = volume of the gas

n = number of moles of the gas

T = temperature of the gas

R = gas constant

At constant temperature and amount of gas remain unchanged, the ideal gas represented as,

where, k is constant.

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
