Matter, Physical and Chemical Properties + Characteristic Prop.

Front

What is Matter?

Back

Matter is anything that has mass and takes up space. It can exist in different states such as solid, liquid, and gas.

Front

What are Physical Properties?

Back

Physical properties are characteristics of matter that can be observed or measured without changing the substance's identity, such as color, boiling point, and density.

Front

What are Chemical Properties?

Back

Chemical properties describe a substance's ability to undergo changes that transform it into different substances, such as reactivity with acids or flammability.

Front

What is a Characteristic Property?

Back

Characteristic properties are unique properties that help identify a substance and distinguish it from others, such as boiling point, melting point, and density.

Front

Which of the following is NOT a CHARACTERISTIC PROPERTY?

Back

Shape is not a characteristic property.

Front

What is Viscosity?

Back

Viscosity is a measure of a fluid's resistance to flow. High viscosity means a fluid flows slowly, while low viscosity means it flows easily.

Front

What is the role of Heat in Chemical Reactions?

Back

Heat can be produced or absorbed during chemical reactions, indicating whether the reaction is exothermic (releases heat) or endothermic (absorbs heat).

Front

What are the three elements needed for combustion?

Back

Fuel, Heat, and Oxygen are required for combustion to occur.

Front

What is the difference between a Substance and a Mixture?

Back

A substance is a form of matter that has a uniform and definite composition, while a mixture is a combination of two or more substances that retain their individual properties.

Front

What is an example of a Substance?

Back

Table Salt (NaCl) and Water (H2O) are examples of substances.
