IPC Semester exam review

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. It occurs when two objects at different temperatures touch each other, allowing heat to flow from the warmer object to the cooler one.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). It occurs when warmer, less dense fluid rises and cooler, denser fluid sinks, creating a circulation pattern.

Front

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves. It does not require a medium to travel through, allowing heat to be transferred through empty space.

Front

What is insulation?

Back

Insulation is a material or method used to reduce the transfer of heat. It helps keep heat in or out of a space, improving energy efficiency.

Front

What is friction?

Back

Friction is the resistance that one surface or object encounters when moving over another. It acts in the opposite direction of motion.

Front

What is sliding friction?

Back

Sliding friction is the force that opposes the motion of two surfaces sliding past each other. It acts to slow down or stop the movement.

Front

What is the unit of energy?

Back

The unit used to measure energy is Joules (J).

Front

What is a force diagram?

Back

A force diagram represents the forces acting on a single object, showing their direction and magnitude.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an external force.

Front

What is mass?

Back

Mass is a measure of the amount of matter in an object, typically measured in kilograms (kg). It is a key factor in determining an object's inertia.
