Question

The volume of a gas is increased from 0.5 L to 2 L while the temperature is held constant. The pressure of the gasa. decrease by a factor of four.b. decreases by a factor of two.c. increases by a factor of eight.d. increases by a factor of two

Answer 1

a. decrease by a factor of four.

Step-by-step explanation

The gas volume and pressure relation were explained by Boyle's law. The law states that at a constant temperature, the pressure of an ideal gas increases as its container volume decreases.

So if the volume of a gas is increased from 0.5 L to 2 L, it implies the volume increase by a factor of (4/0.5) = 4

Since the volume increases by a factor of, then the pressure will decrease by the same factor.

Hence, the correct answer is: The pressure of the gas

a. decrease by a factor of four.
