Gas laws Boyle Charles step by step

What is Boyle's Law?

Boyle's Law states that at constant temperature, the pressure of a gas is inversely proportional to its volume. $\displaystyle P_1V_1 = P_2V_2$.

What is Charles's Law?

Charles's Law states at constant pressure, the volume of a gas is directly proportional to its absolute temperature. $\displaystyle V_1/T_1 = V_2/T_2$.

True or false: Boyle's Law applies only to ideal gases.

True, because it assumes no interactions between gas particles.

Fill in the blank: In Boyle's Law, if volume increases, pressure _____ .

decreases.

Difference between Boyle's Law and Charles's Law

Boyle's Law relates pressure and volume; Charles's Law relates volume and temperature.

What happens to gas volume when temperature increases?

According to Charles's Law, volume increases if pressure is constant.

Define absolute temperature.

Absolute temperature is measured in Kelvin, starting from absolute zero (0 K).

Question: How does pressure affect gas volume?

Increasing pressure reduces volume, according to Boyle's Law.

True or false: Charles's Law can be used at any temperature.

False, because it must be used with absolute temperature (Kelvin).

What is the formula for Boyle's Law?

$\displaystyle P_1V_1 = P_2V_2$.

Question: If volume is halved and temperature is constant, what happens to pressure?

Pressure doubles, according to Boyle's Law.

What does a gas do when heated?

It expands, increasing volume if pressure is constant (Charles's Law).

Fill in the blank: Boyle's Law is valid when temperature is _____ .

constant.

True or false: Volume can never be zero.

True, because gas particles need space to move.
