Physics
This term describes collisions where both total kinetic energy and total momentum is conserved.
What is an elastic collision?
According to the Bronsted-Lowry definition, an acid gives this subatomic particle.
What is a proton?
These are the building blocks of proteins.
What are amino acids?
This type of rock is formed when molten magma or lava cools and solidifies.
What is igneous rock?
This is the process that powers the sun, making heavier elements from lighter ones.
What is nuclear fusion?
This constant relates the energy of a photon to its frequency.
What is Planck's constant?
This intermolecular force occurs only between a hydrogen atom bonded to nitrogen, oxygen, or fluorine.
What is a hydrogen bond?
This is the molecule found in cells for providing energy, especially in its phosphate bonds.
What is ATP?
This layer of the atmosphere has the ozone layer.
What is the stratosphere?
This type of cosmic object has a gravitational pull so intense that nothing, not even light, can escape it.
What is a black hole?
This law gives the electrostatic force between two point charges separated by a distance.
What is Coulomb's law?
This thermodynamic quantity represents the total heat flow of a system at constant pressure.
What is enthalpy?
This process occurs when a cell destroys itself to protect the overall health of an organism.
This geological theory, heavily advanced by Alfred Wegener, explains how Earth’s large outer crust segments move over the mantle.
What is plate tectonics?
The hottest stars have this color.
What is blue?
This physical phenomenon explains the shift in frequency of the waves of a moving source in relation to a stationary observer.
What is the Doppler effect?
When two or more compounds share the same molecular formula but possess entirely different structural arrangements, they are called this.
What are isomers?
The sequence of amino acids in a polypeptide chain represents this specific level of protein structure.
What is primary structure?
This is created when two tectonic plates move away from each other at a line.
This person discovered that the universe was expanding.
Who is Edwin Hubble?
This principle states that it is impossible to know both the exact position and momentum of a quantum particle at the same time.
What is the Heisenberg uncertainty principle?
This law is used to determine the rate of effusion of a gas based on its molar mass.
What is Graham's law of effusion?
This class of organic compounds includes testosterone and estrogen.
What are steroids?
This layer creates Earth's magnetic field.
What is the outer core?
This faint glow filling all space is considered a remnant of the Big Bang.
What is the cosmic microwave background?
