What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What does it mean when a solution is saturated?

Back

A saturated solution is one where no more solute (like sugar) can dissolve in the solvent (like water).

Front

What is the function of a switch in an electric circuit?

Back

The purpose of a switch in an electric circuit is to allow the circuit to be opened or closed.

Front

Define inertia.

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the difference between conduction, convection, and radiation?

Back

Conduction is heat transfer through direct contact, convection is heat transfer through fluid movement, and radiation is heat transfer through electromagnetic waves.

Front

What is a lever?

Back

A lever is a simple machine that consists of a rigid bar that pivots around a fixed point called the fulcrum.

Front

What is the role of the fulcrum in a lever system?

Back

The fulcrum is the pivot point around which the lever rotates.

Front

What is the definition of a saturated solution?

Back

A saturated solution is one that contains the maximum amount of solute that can dissolve at a given temperature.
