Define Matter

What are the properties of matter?

• Taste, smell, sound, touch

• Temperature, pressure, energy, speed

• Mass, volume, density, physical state

• Weight, length, color, shape

List the three states of matter.

• solidus

• solid, liquid, gas

• plasma

• vapor

Give an example of a physical change in matter.

• Boiling water into steam

• Melting ice into water

• Burning wood into ash

• Freezing water into ice

Provide an example of a chemical change in matter.

• Mixing salt and sugar

• Melting of ice

• Rusting of iron

• Boiling of water

Differentiate between mixtures and solutions.

• Mixtures are always in liquid form, while solutions can be in any state.

• Mixtures are homogeneous, while solutions are heterogeneous.

• Mixtures are combinations of substances that are physically combined, while solutions are mixtures where one substance dissolves in another.

• Mixtures are chemically combined substances, while solutions are physically combined.

What is the difference between an element and a compound?

• An element is a mixture of different atoms, while a compound is made up of identical atoms.

• An element consists of only one type of atom, whereas a compound consists of two or more different types of atoms bonded together.

• Elements and compounds are the same thing.

• Elements are always in liquid form, compounds are always in solid form.

Explain the concept of density in matter.

• Density is the mass of a substance per unit volume.

• Density is the color of a substance per unit volume.

• Density is the weight of a substance per unit volume.

• Density is the temperature of a substance per unit volume.

How does temperature affect the state of matter?

• Temperature affects the state of matter by changing the color of particles.

• Temperature affects the state of matter by increasing the volume of particles.

• Temperature affects the state of matter by changing the kinetic energy of particles.

• Temperature affects the state of matter by altering the atomic number of particles.

Describe the process of evaporation.

• Evaporation is the process by which a solid turns into a gas due to an increase in pressure.

• Evaporation is the process by which a liquid turns into a solid due to an increase in temperature.

• Evaporation is the process by which a liquid turns into a gas due to an increase in temperature.

• Evaporation is the process by which a gas turns into a liquid due to a decrease in temperature.

What is the Law of Conservation of Mass?

• Mass can be destroyed without any consequences

• Mass can be transformed into energy without any limitations

• Mass can be created out of nothing

• Mass cannot be created or destroyed, only transformed.
