Understanding Gay-Lussac's Law

What does Gay-Lussac's Law state about the relationship between pressure and temperature of a gas?

• They are equal.

• They are directly proportional.

• They are inversely proportional.

• They are unrelated.

If the temperature of a gas is doubled, what happens to the pressure according to Gay-Lussac's Law?

• The pressure quadruples.

• The pressure is halved.

• The pressure doubles.

• The pressure remains the same.

What must remain constant for Gay-Lussac's Law to apply?

• Volume and mass

• Mass and pressure

• Temperature and pressure

• Volume and temperature

What is the formula derived from Gay-Lussac's Law?

• P1/T1 = P2/T2

• P1*T2 = P2*T1

• P1 - T1 = P2 - T2

• P1 + T1 = P2 + T2

Why is it important to use Kelvin in calculations involving Gay-Lussac's Law?

• Kelvin is the standard unit for pressure.

• Kelvin is the standard unit for volume.

• Kelvin is easier to calculate.

• Kelvin avoids negative temperatures.

In a problem where a gas exerts 4.5 atmospheres at 25°C, what is the first step to find the pressure at 50°C?

• Convert the temperature to Kelvin.

• Convert the pressure to Kelvin.

• Double the pressure.

• Halve the temperature.

If a gas's pressure decreases from 760 torr to 320 torr, what must be calculated to find the initial temperature?

• Final pressure

• Initial temperature

• Initial pressure

• Final temperature

What happens to the pressure of a gas if its temperature decreases by a factor of 1/4?

• The pressure increases by a factor of 4.

• The pressure decreases by a factor of 1/4.

• The pressure remains constant.

• The pressure doubles.

In the example where a gas at 45°C and 3.2 atmospheres has its pressure increased to 5 atmospheres, what is the expected change in temperature?

• The temperature will double.

• The temperature will increase.

• The temperature will remain the same.

• The temperature will decrease.

What is the final temperature of a gas if its pressure increases from 3.2 to 5 atmospheres, starting at 318K?

• 534.375K

• 318K

• 496.875K

• 225K
