The expression below was formed by combining different gas laws. V is proportional to StartFraction n T over P EndFraction. Whic

Ronch [10]

Answer:

The Ideal gas law

Explanation:

From the given question, we have:

V $\alpha$ $\frac{nT}{P}$

where each variable has its usual meaning.

Thus,

V = $\frac{nRT}{P}$

where R is the ideal gas constant

cross multiply to have;

PV = nRT

This implies that the volume of the gas is directly proportional to the number of moles of the gas.

Therefore, the law can be used to determine the relationship between the volume and number of moles is the ideal gas law.

Generally, what happens to the rate of dissolution for a solid solute when you change from stirring a solution to not stirring i

Makovka662 [10]

The rate of dissolution of a solid solute into the solution decreases when you stop stirring it. Generally, stirring increases the dissolution rate of a solid into a solution. An example is coffee with sugar, the sugar dissolves faster when stirred versus when left to dissolve on its own.
