Kinetic Molecular Theory Gas Laws Jeopardy Boyle’s Law Charles Law Combined Gas Law Formulas and units Kinetic Molecular Theory 10 20 30 40 50

Define Boyle’s Law The volume of The volume of a gas is inversely proportional to the pressure of the gas. roportional to the pressure of the gas. Category 1 - 10

For two sets of pressure and volume measurements mathematically how do you write Boyle’s Law ? Category 1 - 20 P1V1 = P2V2

According to Boyle’s Law When pressure of a gas increases What would happen to its volume? Decreases

A 2L Helium Balloon has a pressure of 100kPa. What is its new volume when it is take to a mountain top where the pressure is 50 kPa? Volume is= 4L

What pressure is required to change the volume to 0.250 L A bicycle pump contains 0.750L of air at 101 kPa. If the pump is closed, What pressure is required to change the volume to 0.250 L 303 kPa

Define Charles Law Volume of a gas is directly proportional to temperature When pressure is kept constant.

How can you write the mathematical expression when two sets of volume and temperature measurements are given? V1T2 = V2T1

What will happen to the volume of a gas when its temperature is increased ? Volume also increases

On Kelvin temperature scale what is absolute zero? Absolute zero is 0°K or -273°C

A gas cylinder has a gas of volume of 2. 5L at 25°C A gas cylinder has a gas of volume of 2.5L at 25°C. When the temperature is increased to 95°C what is its final volume? 3.087 L

Name the quantities that involve In combined gas law. Pressure, Temperature and Volume

Mathematically how do you express combined gas law P1V1 = P2V2 T1 T2

Define combined gas law The product of the pressure and volume of a gas sample is Proportional to its absolute temperature in Kelvin scale. PV = kT

A balloon has a volume of 5. 00 L at 20°C and 100 kPa A balloon has a volume of 5.00 L at 20°C and 100 kPa. What is its new volume at 35°C and 90 kPa. 9.7 L

A cylinder of helium gas has a volume of 1. 0 L A cylinder of helium gas has a volume of 1.0 L. The gas in the cylinder exerts a pressure of 800 kPa at 30°C . What volume would this gas occupy at SATP? 6.67 L

What is STP means? Standard Temperature and Pressure

What are the exact values of Temperature and Pressure at STP? Temperature = 0°C and Pressure = 101.325 kPa

What is SATP? Standard Ambient Temperature and Pressure

what are the exact values of Temperature and Pressure at SATP? Temperature = 25°C and Pressure = 100 kPa

List all the units given for pressure Atmospheres, Kilo Pascal, Torr, mm Hg

How do you define Kinetic Molecular Theory All substances contain particles that are in constant, random motion.

What type of motion we see in the particles of Solids? Vibrational motion

Name the energy possessed by the moving particles Kinetic Energy

What type of motion does liquid particles possess? Vibrational, Rotational, and Translational

Why do translational motion is most significant in Gases? This produces random collisions and the most disordered state with no organization.
