Which of the following changes would increase the pressure of a gas if moles are held constant? a. part of the gas is removed b. the temperature is decreased c. nothing is changed d. the container size is decreased

The correct answer is option D. The container size is decreased.

Explanation:

Hello!

Let's solve this!

The formula used in gases is PV = nRT

If we clear the pressure:

P = nRT / V

This indicates an inversely proportional relationship between volume and pressure. So if I need to increase the pressure, I need to decrease the volume or vice versa.

After analysis, the correct answer is option D. The container size is decreased, which indicates a decrease in volume.

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.
