What do gas laws determine?

The pressure, volume, and temperature of gas.

100
What are the 6 main changes of state of matter?

Melting, Freezing, Sublimation, Deposition, Condensation, and Vaporization

100

When is the heating curve flat?

 during phase changes


100

What is a liquid to a solid called?

Freezing.
200

Why are properties important in chemistry?

enable us to differentiate one material from another

200

What is the ideal gas law formula?

PV=nRT

200

How many basic changes of states of matter are there?

melting, freezing, sublimation, deposition, condensation, and vaporization (6)

200

What is a heating curve?

show how the temperature changes as a substance is heated up

200

What type of energy does a heating curve absorb?

they absorb kinetic energy

300

What is a property?

a characteristic of a particular substance that can be observed in a chemical reaction

300

What are the gas laws applicable to?

Only for gases

300
What is gas?

Fastest moving particles of all the states of matter.

300

What is a triple point?

The temperature and pressure at which the soild, liquid, and vapor phases of a pure substance can coexist in equilibrium

300

What do the lines on the diagrams show?

They indicate the boundaries between the different states.

400

What different types of bonding exist, and how are they different?

ionic, covalent, and metallic

400

How many gas laws are there?

3, Boyles law, Charles law, Avogrados law

400

Define Melting point and boiling point.

Melting point - is the temperature at which a solid becomes a liquid at normal atmospheric pressure.

Boiling point - the temperature at which a liquid boils and turns to vapor

400

What is the Critical point?

a point at which the derisive is zero or undefined.

400

What are the three parts of the phase diagram?

 solid, liquid, and gaseous states of the substance.

500

How do ionic and covalent bonds form?

Covalent bonding involves the sharing of electrons between two or more atoms. Ionic bonds form when two or more ions come together and are held together by charge differences

500
What is the Boyles law?

Pressure varies inversely with volume.

500

What are the factors affecting the states of matter change?

Temperature and pressure

500

What do the slope lines on a heating curve represent?

the rising temperature and phase changes in the substance.

500

What is a phase change diagram?

a graphical representation of the physical states of a substance under different conditions of temperature and pressure.
