What is the ideal gas constant?

a. it is a constant that applies only at stp.
b. it is a specific constant for a particular gas.
c. it is a universal constant used for all gases.
d. it is a constant that depends on the conditions.

Ideal gas constant is a universal constant used for all gases

Explanation:

In Ideal Gases Law, the Ideal gas constant is called R.

It can also be used in Van der Waals equation or, in thermodynamic equations.

R = 0.082 l.atm/mol.K

It is related to the Boltzmann constant, a number that links energy units with temperature units.

the major pests we deal with are insects, weeds and fungal diseases. a pesticide is a product, whether organic or chemical, used to kill the target pest. there are other techniques gardeners should use that can prevent the severe infestations that make the use of pesticides necessary
