Kinetic Energy
What is the SI unit of energy?
What is Joules (J)?
What is the weakest IMF?
What is London Dispersion Forces (LDFS)?
This phase change occurs when a solid becomes a liquid.
What is melting?
This gas law states that the pressure of a gas is inversely proportional to its volume, assuming temperature is constant.
What is Boyle’s Law?
This property allows liquids to resist an external force at the surface, often seen in water droplets.
What is surface tension?
What is Dalton's Law of Partial Pressure?
What is the total pressure is equal to the sum of the partial pressures?
List one of the Intramolecular forces
What is ionic, covalent, metallic bonds?
This phase change occurs when a gas becomes a liquid.
What is condensation?
According to this gas law, the volume of a gas increases directly with temperature when pressure is constant.
What is Charles’s Law?
In liquids, this force causes molecules to stick to other substances, like water climbing up a paper towel.
What is adhesion?
What is a way to measure pressure?
What is a Barometer/Manometer?
What are the forces between different molecules?
What is Intermolecular Forces?
During this phase change, a substance goes directly from a solid to a gas without becoming a liquid first.
What is sublimation?
In the ideal gas law, represented by PV = nRT, what does the variable n stand for?
What is the number of moles?
This property describes how easily a liquid flows and is inversely related to the strength of intermolecular forces.
What is viscosity?
What is one of the K-M theory assumptions?
What is gases are particles but behave like moving marbles, Particles move in a straight line until they hit something, Gas particles are much smaller than the distance between particles, No force attraction between gas particles or the walls of the container, All collisions are perfectly elastic, The temperature of the gas depends on the average kinetic energy?
In this state of matter, particles experience very strong intermolecular forces that limit their movement to vibrations in fixed positions.
What is a solid?
During a phase change, the temperature of a substance remains constant. This is because the energy added or removed is used to do what?
What is break or form intermolecular forces?
A sample of gas is compressed from 4.0 L to 2.0 L at constant temperature. What happens to the pressure, according to Boyle’s Law?
It doubles.
In this phenomenon, the vapor pressure of a liquid increases with temperature, eventually leading to this event where liquid molecules escape the surface to form a gas.
What is boiling?
This state of matter has the highest average kinetic energy at a given temperature, and its particles move independently at high speeds with negligible intermolecular forces.
What is a gas?
This type of intermolecular force occurs between polar molecules and is responsible for water's unusually high boiling point compared to similar-sized molecules.
What is hydrogen bonding?
This endothermic phase change requires the most energy per mole because it involves completely overcoming intermolecular forces.
What is vaporization (or boiling)?
A gas at 300 K and 1.00 atm is heated to 600 K in a rigid container. What happens to the pressure, assuming ideal behavior?
It doubles to 2.00 atm.
This term refers to the ability of a solid to dissolve in a liquid to form a homogeneous mixture, like salt dissolving in water.
What is solubility?
