1Which state of matter has a definite volume but takes the shape of its container?

A.Liquid

B.Solid

C.Gas

D.Plasma

Explanation: A liquid has a fixed volume because its particles remain close together, but it flows and takes the shape of whichever container holds it. Solids maintain both a fixed shape and volume, while gases expand to fill any container.

2A student measures 100 grams of water and 10 grams of salt. After dissolving the salt completely in the water, what is the total mass of the solution?

A.110 grams

B.100 grams

C.90 grams

D.10 grams

Explanation: According to the principle of conservation of mass, matter cannot be created or destroyed during a physical change. When 10 grams of salt dissolve in 100 grams of water, the total mass equals 100 + 10 = 110 grams.

3Which of the following is an example of a physical change?

A.Melting an ice cube

B.Baking a cake

C.Rusting of an iron nail

D.Burning a piece of wood

Explanation: Melting an ice cube changes water from solid to liquid, which is a physical change in state. The chemical composition remains H2O throughout. Baking, rusting, and burning are chemical changes that produce new substances.

4What direction does the force of Earth's gravity always pull objects near its surface?

A.Down toward the center of Earth

B.Up toward the sky

C.To the east following Earth's rotation

D.Toward the nearest ocean

Explanation: Earth's gravitational force attracts all matter near its surface straight down toward the center of Earth. This force gives objects weight and causes dropped items to fall downward regardless of location on the globe.

5Which state of matter maintains both a fixed shape and a fixed volume regardless of the container it is placed in?

A.Solid

B.Liquid

C.Gas

D.Vapor

Explanation: Solids have particles tightly packed in rigid arrangements, giving them a definite shape and a definite volume. Liquids change shape to fit containers, and gases change both shape and volume.

6Which observation provides the clearest evidence that a chemical change has taken place?

A.A new substance with different properties is formed

B.A solid changes into a liquid

C.A large block is broken into smaller pieces

D.A liquid is stirred and turns cloudy temporarily

Explanation: A chemical change always results in the formation of one or more new chemical substances with distinct chemical and physical properties. Melting, breaking, or temporary mixing are physical changes.

7When a metal spoon is placed in a hot cup of soup, why does the spoon's handle become warm?

A.Heat transfers from the warm soup to the cooler spoon

B.Cold travels from the spoon into the warm soup

C.The spoon creates its own heat energy

D.Air inside the spoon frictionally heats up

Explanation: Thermal energy naturally flows from warmer objects to cooler objects until temperature balances out. Metals are good thermal conductors, so heat moves quickly from the hot soup through the spoon to its handle.

8Which tool is best suited for measuring the mass of a small rock in a science lab?

A.A balance scale

B.A graduated cylinder

C.A thermometer

D.A meter stick

Explanation: A balance scale (such as a triple beam balance or digital balance) measures mass in grams. Graduated cylinders measure liquid volume, thermometers measure temperature, and meter sticks measure length.

9What happens to the shape and volume of a gas when it is moved into a larger container?

A.It expands to fill the entire volume and shape of the new container

B.It keeps its original shape and volume

C.It contracts into a smaller solid shape

D.Its mass decreases as it expands

Explanation: Gas particles move freely and spread apart, expanding to completely fill whatever container holds them. The shape and volume of the gas match the shape and volume of the container, while total mass stays constant.

10What is the primary original source of light and heat energy for Earth's surface?

A.The Sun

B.The Moon

C.Earth's core

D.Volcanoes

Explanation: The Sun provides nearly all of the light and thermal energy that reaches Earth's surface. This solar energy drives Earth's weather, ocean currents, and photosynthesis in ecosystems.
