Chemical Properties of Matter

The video tutorial discusses the differences between physical and chemical properties of matter. Chemical properties are defined by a substance's ability to change into a new substance with different properties. Examples include flammability, where wood burns to produce heat, smoke, and ashes, and the ability of iron to rust when reacting with oxygen. These examples illustrate the concept of chemical properties and their significance in understanding material interactions.

What distinguishes chemical properties from physical properties?

• Chemical properties describe the color of a substance.

• Chemical properties involve the ability to change into new substances.

• Chemical properties are related to the mass of a substance.

• Chemical properties are about the texture of a substance.

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

• The melting point of ice.

• The density of water.

• The flammability of wood.

• The hardness of a diamond.

What happens when wood is burned?

• It remains unchanged.

• It changes into heat energy, smoke, and ashes.

• It becomes a liquid.

• It turns into water and carbon dioxide.

What is a chemical property of iron?

• It is a good conductor of electricity.

• It can rust when exposed to oxygen.

• It has a high melting point.

• It is magnetic.

Which process demonstrates a chemical property?

• Cutting paper.

• Boiling water.

• Freezing ice cream.

• Rusting of iron.
