Matching Physical Properties Quiz

The ability of a material to be hammered into thin sheets.

The ability of a material to be drawn into wires.

The way a substance looks when light reflects off of it.

The temperature at which a liquid changes into a gas.

The temperature at which a solid changes into a liquid.

A chemical change is a process that results in the formation of new substances with different properties.

A change in colour can indicate that a new substance has been formed, which is a characteristic of a chemical change.

Release or absorption of heat or light energy is a sign that a chemical reaction is occurring.

A physical change is a change in the form or appearance of a substance but not its chemical composition. It is usually reversible.

A change in state, such as melting or freezing, is a physical change. The chemical composition remains the same.

Factors that are non-living in an ecosystem (e.g., sunlight, temperature, water).

The variety of life in a particular area.

The study of the relationship between organisms and their environment.

The natural environment of an organism.

The layer of gases surrounding the Earth.

The process by which plants produce food using sunlight.

The maximum population size that an environment can support.

A series of organisms in which each feeds on the preceding one.

The process by which organisms break down glucose (sugar) in the presence of oxygen to release energy (ATP) for their cells. This process produces carbon dioxide and water as byproducts.

The series of feeding relationships in an ecosystem, where energy is transferred from one organism to another.

The position an organism occupies in a food chain/web based on what it eats and what eats it.

The buildup of electric charge on the surface of a material due to rubbing against another material, causing one material to have a surplus of electrons (negative charge) and the other a deficit (positive charge).

The continuous flow of electrons through a closed circuit, measured in amperes (A).

A series that ranks materials based on their tendency to gain or lose electrons during friction. The higher the material on the list, the more likely it is to gain electrons and become negatively charged.

An instrument used to detect static charges. It consists of a metal rod with two thin metal leaves hanging from it. When a charged object is brought near the electroscope, the leaves repel each other.

A device that controls the flow of electrons in a circuit by opening or closing the circuit, interrupting or allowing the flow of electricity.

A path that allows electrons to flow continuously from a power source, through a load, and back to the power source. It must be a closed loop for current to flow.

A circuit where all components are connected in a single loop. If one component fails, the entire circuit is broken.

A circuit where components are connected in multiple paths. If one component fails, the others can still function.

The ratio of useful energy output to total energy input, expressed as a percentage.

As resistance increases, current decreases, assuming voltage remains constant.

Homes are wired in parallel because each device has its own path for electricity to flow, so a malfunction in one device doesn't affect other devices. Also, each device receives the full voltage.

The total voltage across a series circuit is equal to the sum of the voltage drops across each component. Voltage is measured in volts (V), current in amperes (A), and resistance in ohms (Ω).

Electrical devices are not 100% efficient because some energy is lost as heat, light, or sound.

The resistance of a circuit is calculated using Ohm's Law: Resistance (R) = Voltage (V) / Current (I)

Turning a light bulb on closes the circuit, allowing electricity to flow through the filament, causing it to heat up and emit light.

The cost of electricity used is calculated by multiplying the power in kilowatt-hours (kWh) by the cost per kWh.

The path a celestial body takes as it orbits another object , like the Earth revolving around the Sun.

The spinning motion of a celestial body on its axis, like the Earth rotating on its axis causing day and night.

The region between Mars and Jupiter where most asteroids are found.

Planets made primarily of rock and metal, typically smaller and denser than gas giants. Examples include Mercury, Venus, Earth, and Mars.

Planets composed mainly of gas like hydrogen and helium, typically larger and less dense. Examples include Jupiter, Saturn, Uranus, and Neptune.

A substance that cannot be broken down into simpler substances by ordinary chemical means.

A substance made up of two or more elements chemically combined in a fixed ratio.

A combination of two or more substances that are not chemically combined and can be separated by physical means.

A change in the form or appearance of a substance, but not its chemical composition.

A change that results in the formation of one or more new substances with different properties.

A community of interacting organisms and their physical environment.
