Understanding Matter and Its Changes

The video tutorial by Ka Febri on the Smart channel covers the basics of matter, its types, and their characteristics. It explains the differences between solids, liquids, and gases, and describes various phase changes such as melting, freezing, evaporation, and condensation. The tutorial also distinguishes between physical and chemical changes, and provides an understanding of elements, compounds, and mixtures, highlighting their differences and examples.

Which of the following is a characteristic of solid matter?

• Shape changes with container

• Particles are closely packed

• Volume changes with container

• Particles are far apart

What happens to the volume of a liquid when it is transferred to a different container?

• It becomes zero

• It increases

• It decreases

• It remains the same

What is the process called when a liquid turns into a gas?

• Condensation

• Evaporation

• Melting

• Freezing

Which process involves a gas turning into a liquid?

• Sublimation

• Crystallization

• Melting

• Condensation

What type of change is it when a substance changes its state but not its chemical identity?

• Biological change

• Nuclear change

• Physical change

• Chemical change

Which of the following is an example of a chemical change?

• Melting ice

• Boiling water

• Breaking glass

• Rusting iron

What is a characteristic of a compound?

• Has a fixed ratio of elements

• Can be separated by physical means

• Made of one type of atom

• Properties are the same as its elements

Which of the following is true about mixtures?
