5th Gr Physical Sci Vocab Review

A complete circuit is defined as:

• A circuit with a power source, conductors, and a load that forms a closed loop.

• A circuit with only a power source and conductors.

• A circuit with a power source, conductors, and a load that forms an open loop.

• A circuit with only conductors and a load.

Electricity is:

• a form of energy resulting from the existence of charged particles

• a type of chemical reaction

• a form of kinetic energy

• a type of magnetic field

Thermal energy in the context of circuits is defined as:

• The energy stored in the electric field of a capacitor

• The energy dissipated as heat due to resistance

• The energy stored in the magnetic field of an inductor

• The energy supplied by a battery

A pattern is:

• a repeated decorative design

• a single occurrence

• a random arrangement

• an undefined concept

What is light energy?

• Energy that we can see, like sunlight or a flashlight.

• Energy that is stored in chemical bonds.

• Energy that is produced by nuclear reactions.

• Energy that is generated by moving objects.

What is solubility?

• The ability of a substance to dissolve in a solvent

• The process of a solid turning into a liquid

• The rate at which a substance dissolves

• The temperature at which a substance dissolves

What is refraction? When light bends as it passes through a different medium, like a straw in water.

• Refraction

• Reflection

• Diffraction

• Absorption

What is relative density?

• Relative density is the ratio of the density of a substance to the density of a reference substance.

• Relative density is the measure of the mass of an object per unit volume.

• Relative density is the weight of an object compared to its volume.

• Relative density is the comparison of the volume of a substance to its mass.

What is physical state?

• A property of matter that describes its form, such as solid, liquid, or gas.

• A measure of the amount of matter in an object.

• The energy required to change the temperature of a substance.

• The force exerted by a substance per unit area.

Testing means:

• Evaluating the functionality of a system or component

• Writing code

• Designing a user interface

• Deploying software
