What are 'Spectral Lines'?

• Distinct lines in a spectrum caused by emission or absorption of light at specific wavelengths by a substance.

• Continuous bands of color in a spectrum without any interruptions.

• Random patterns of light and dark areas in a spectrum.

• Uniform distribution of light across all wavelengths in a spectrum.

Define 'Conduction' and provide a real-world example or drawing.

• Conduction is the transfer of heat through a fluid.

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

• Conduction is the transfer of heat through electromagnetic waves.

• Conduction is the transfer of heat through the movement of air.

What is 'Convection'?

• The transfer of heat through direct contact.

• The transfer of heat through fluid movement.

• The transfer of heat through electromagnetic waves.

• The transfer of heat through solid materials.

What is 'Radiation'?

• The emission of energy as electromagnetic waves or as moving subatomic particles.

• The process of converting light energy into chemical energy.

• The transfer of heat through direct contact between materials.

• The movement of air or liquid that transfers heat from one place to another.

What are 'Energy Levels' in the context of atomic physics?

• The specific energies that electrons can have when occupying specific orbitals around a nucleus.

• The amount of energy required to remove an electron from an atom.

• The energy released when an atom undergoes a chemical reaction.

• The energy required to break a chemical bond.

What is the 'Law of Conservation of Energy'?

• Energy can be created or destroyed.

• Energy can be transformed from one form to another, but cannot be created or destroyed.

• Energy is always lost in the form of heat.

• Energy is only conserved in closed systems.

What is a 'Series Circuit'?

• A circuit where components are connected along a single path.

• A circuit where components are connected in parallel paths.

• A circuit with no electrical components.

• A circuit that only uses batteries.

What is a 'Parallel Circuit'?

• A circuit where components are connected along a single path

• A circuit where components are connected on separate branches

• A circuit with no electrical components

• A circuit that only uses direct current

What is 'Electromagnetic Force'?

• A force that acts between charged particles and is responsible for electricity and magnetism

• A force that acts only at the atomic level and is responsible for nuclear reactions

• A force that acts between masses and is responsible for gravity

• A force that acts only in the presence of a medium and is responsible for sound waves

What does 'Proportional' mean?

• Having a constant ratio or relation with another quantity.

• Being equal in size or amount.

• Being unrelated or independent.

• Having a random relationship.
