It’s the type of collision in which kinetic energy is perfectly conserved.

What is Elastic Collisions?

100

This law of thermodynamics states that energy cannot be created or destroyed, only transferred or transformed.

What is the 1st Law of Thermodynamic?

100

This subatomic particle has a negative charge and orbits the nucleus.

What is an electron?

100

This ancient Greek philosopher taught that natural phenomena should be explained through reason, not mythology, earning him the title "Father of Western Philosophy."

Who is Socrates?

100

The natural satellite of Earth

What is the Moon?

This famous thought experiment highlights the paradox of quantum superposition by involving a cat and a sealed box.

What is Schrödinger's Cat?

200

This law states that the disorder of the universe always increases for any spontaneous process, explaining why heat naturally flows from hot objects to cold ones.

What is the Second Law of Thermodynamics?

200

This term describes a substance that speeds up a reaction without being consumed.

What is a catalyst?

200

This scientist built the first successful model of the atom using quantized orbits but later expanded the idea of complementarity in quantum theory.

Who is Niels Bohr?

200

This boundary around a black hole marks the point beyond which nothing-not even light-can escape.

What is an event horizon?

300

This fictitious force appears in a rotating reference frame and causes the apparent outward push on objects moving in circles.

What is centrifugal force?

300

What is the lowest possible point on the thermodynamic scale, where a system would reach its minimum internal energy and classical particle motion would theoretically cease?

What is absolute 0?

300

This principle states that no two electrons in an atom can have the same set of four quantum numbers

What is Pauli's Exclusion Principle?

300

Known for the discovery of Radium, this person was the first person to win 2 noble prizes in different fields.

Who is Marie Curie

300

Named after a famous telescope, this law states that galaxies and distant objects are moving away from us at speeds proportional to their distance.

What is Hubble's Law

400

This German physicist introduced the idea of quantized energy in 1900.

Who is Max Planck?
400

This concept explains why adding heat to a solid at its melting point does not raise its temperature.

What is energy of fusion?

400

This spectroscopy law relates absorbance to concentration and path length through a solution?

What is Beer-Lambert Law?

400

This physicist discovered the neutron in 1932, enabling the development of nuclear fission

Who is James Chadwick

400

This effect causes the apparent frequency of light to shift based on the relative motion of the source and observer

What is the Doppler Effect (What is red shifting)

500

 This quantum principle states that the more precisely you determine a particle’s position, the less precisely you can know its momentum, making exact knowledge of both at the same time impossible

What is Heisenberg's Uncertainty's Principle

500

This exotic phase of matter, formed at temperatures near absolute zero, occurs when a collection of bosons collapses into the lowest energy state, causing quantum effects to appear on a macroscopic thermodynamic scale.

What is a Bose-Eistein Condensate?

500

This quantum-mechanical principle states that particles can exist in multiple states simultaneously until measured as seen in the behavior of electrons in atomic orbitals.

What is superposition?

500

As the universe reaches a state of maximum entropy, this structure forms as a result of the energy of the universe forming a complex structure that is named after this famous physicists known for his distribution.

What is the Boltzmann Brain?

This limit defines the maximum mass a white dwarf can have before collapsing into a neutron star or black hole.
