C165 Integrated Physical Sciences - Set 3 - Part 2

Correct Answer: Inertia

Inertia is the property of an object that resists changes to its state of motion unless acted upon by an external force.

Correct Answer: Solar energy

Solar energy heats water, causing it to evaporate, driving the water cycle.

Correct Answer: Ampere

The ampere (A) is the SI unit for measuring electric current, which represents the flow of electrical charge.

Correct Answer: Diffraction

Diffraction occurs when waves bend around obstacles or pass through narrow openings, spreading out as a result.

Correct Answer: Watt

Power is measured in watts (W) in the SI system, which is equivalent to one joule per second.

Correct Answer: Chemical weathering

Chemical weathering involves the breakdown of rocks through chemical reactions, often involving water and other chemicals in the environment.

Correct Answer: Igneous rock

Igneous rocks are formed by the cooling and solidification of magma or lava.

Correct Answer: Convection currents in the mantle

Convection currents in Earths mantle, caused by the transfer of heat, are responsible for the movement of tectonic plates.

Correct Answer: Iron and nickel

Earths inner core is primarily composed of solid iron and nickel, which contributes to Earth's magnetic field.

Correct Answer: Evaporation

Evaporation is the process by which liquid water is converted into water vapor, typically due to heat.

Correct Answer: Igneous, sedimentary, metamorphic

The three main rock types are igneous, sedimentary, and metamorphic, classified based on their formation processes.

Correct Answer: It quadruples

Kinetic energy is proportional to the square of the speed, so doubling the speed results in a fourfold increase in kinetic energy.

Correct Answer: Law of Conservation of Energy

The Law of Conservation of Energy states that energy cannot be created or destroyed, only transformed or transferred.

Correct Answer: Refraction

Refraction occurs when light bends as it passes from one medium to another, due to changes in its speed.

Correct Answer: Elasticity

Elasticity refers to the ability of a material to return to its original shape after deformation.

Correct Answer: Radio waves

Radio waves have the longest wavelengths in the electromagnetic spectrum, typically used for communication.

Correct Answer: Na

The chemical symbol for sodium is Na, derived from the Latin name natrium.

Correct Answer: Conductivity

Conductivity refers to a materials ability to allow the flow of electrical current.

Correct Answer: A warm front

A warm front forms when warm air rises over a cold air mass, often bringing gentle rain or snow followed by warmer weather.

Correct Answer: Nitrogen

Nitrogen makes up about 78% of Earths atmosphere, making it the most abundant gas.
