What is the ideal gas law equation?

• P = nRT/V

• P = V/nRT

• PV = nRT

• PV = RT/n

According to Boyle's law, what happens to the volume of a gas if the pressure is increased?

• The volume of a gas becomes solid if the pressure is increased.

• The volume of a gas decreases if the pressure is increased.

• The volume of a gas remains the same if the pressure is increased.

• The volume of a gas increases if the pressure is increased.

What is the mathematical expression for Charles's law?

• V1/T1 = V2/T2

• V1 - T1 = V2 - T2

• V1 * T1 = V2 * T2

• V1 + T1 = V2 + T2

How does the volume of a gas change with temperature according to Charles's law?

• The volume of a gas decreases with an increase in temperature

• The volume of a gas remains constant regardless of temperature

• The volume of a gas increases with an increase in temperature, and decreases with a decrease in temperature.

• The volume of a gas is not affected by temperature

What is the formula for gas stoichiometry?

• The formula for gas stoichiometry is NaCl

• The formula for gas stoichiometry is H2O

• The formula for gas stoichiometry is 2+2=5

• The formula for gas stoichiometry is the same as the general stoichiometry formula, which is based on the balanced chemical equation for the reaction.

If the pressure of a gas is doubled at constant temperature, what happens to its volume according to Boyle's law?

• Volume will be halved

• Volume will be tripled

• Volume will be quadrupled

• Volume will remain the same

What are the units of the ideal gas constant in the ideal gas law equation?

• Pascals per cubic meter

• Grams per liter

• The units of the ideal gas constant in the ideal gas law equation are joules per mole per kelvin (L*atm/mol*K).

• Meters per second

How is the amount of gas in moles related to the volume of the gas in the ideal gas law?

• Directly proportional

• Varies randomly

• Indirectly proportional

• Not related at all

What is the relationship between the pressure and volume of a gas in Boyle's law?

• The relationship is random

• They are not related

• They are directly proportional

• The relationship between the pressure and volume of a gas in Boyle's law is that they are inversely proportional.

How is the molar volume of a gas at STP related to the ideal gas constant?

• The molar volume of a gas at STP is directly related to the ideal gas constant through the equation V = RT/P.

• The molar volume of a gas at STP is related to the ideal gas constant through the equation V = P/RT

• The molar volume of a gas at STP is not related to the ideal gas constant

• The molar volume of a gas at STP is inversely related to the ideal gas constant
