What is the volume of a rectangular prism?

Back

The volume of a rectangular prism is calculated using the formula: Volume = length × width × height.

Front

What is a chemical reaction?

Back

A chemical reaction is a process that leads to the transformation of one set of chemical substances to another, often indicated by changes such as color, temperature, or the formation of gas.

Front

What is a hypothesis?

Back

A hypothesis is a proposed explanation for a phenomenon that can be tested through experimentation.

Front

How do you calculate the volume of an object?

Back

To calculate the volume, you multiply the object's dimensions (length, width, height for rectangular shapes) or use specific formulas for other shapes.

Front

What is the significance of gas formation in a chemical reaction?

Back

The formation of gas is a common indicator that a chemical reaction has occurred.

Front

What is the formula for calculating the volume of a cylinder?

Back

Volume = π × radius² × height.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

What is the unit of volume in the metric system?

Back

The unit of volume in the metric system is cubic centimeters (cm³) or liters (L).

Front

What is the principle of conservation of mass?

Back

The principle of conservation of mass states that mass is neither created nor destroyed in a chemical reaction.

Front

What is a physical change?

Back

A physical change is a change that affects one or more physical properties of a substance without altering its chemical composition.
