Elements and Counting Atoms
The chemical symbol "O" represents this life-supporting element on the Periodic Table.
What is Oxygen?
Tearing a piece of paper is this type of change
What is physical change?
If a sprinter runs 100 meters in 10 seconds, this is their average speed.
What is 10 meters per second (m/s)?
Touching a hot pan burns your hand through this type of heat transfer, which requires direct physical contact.
What is conduction?
This biological sequence, also known as the citric acid cycle, is a series of chemical reactions used by all aerobic organisms to release stored energy through the oxidation of acetyl-CoA.
What is the Krebs cycle?
In the chemical formula for water, H₂O, this is the number of hydrogen atoms present.
What is 2?
Bubbling (gas production), an unexpected temperature change, and the formation of a solid precipitate are all common signs that this has occurred.
What is a chemical change?
A swimmer pushes backward on the water, and the water pushes the swimmer forward, perfectly demonstrating this specific Law of Motion.
What is Newton's Third Law (Law of Action-Reaction)?
Ocean waves, sound waves, and seismic waves all travel from one place to another in order to transfer this, but they do not transfer matter.
What is energy?
This is the highly technical term for what happens to a frog's car when it breaks down on the side of the road.
What is it gets toad?
This is the total number of atoms in a single molecule of ammonia, NH3
What is 4?
This fundamental scientific law states that matter cannot be created or destroyed during a chemical or physical change.
What is the Law of Conservation of Mass?
If a 10 Newton force pushes a box to the right, and a 4 Newton force pushes it to the left, this is the net force acting on the box.
What is 6 Newtons to the right?
As a thermometer measures a higher temperature in a pot of boiling water, it means the water molecules are moving faster and have more of this specific type of energy (Not thermal)
What is kinetic energy?
This is the exact mathematical boundary, or radius, around a singularity where the escape velocity is equal to the speed of light, famously making it the "point of no return" for a black hole.
What is the event horizon (or the Schwarzschild radius)?
Looking at the formula for glucose, C₆H₁₂O₆, this specific element has the greatest number of atoms.
What is Hydrogen?
If 10 grams of baking soda react completely with 50 grams of vinegar, the total mass of the resulting products must equal this amount.
What is 60 grams?
According to Newton's Second Law (F=ma), it takes more force to accelerate a bowling ball than a tennis ball because the bowling ball has more of this.
What is mass?
This type of heat transfer explains why the second floor of a house is often warmer than the first floor, as warmer, less dense fluid rises and cooler, denser fluid sinks.
What is convection?
This is what you do with a dead chemist.
What is barium?
This is the total number of atoms present in one molecule of calcium hydroxide: Ca(OH)₂
What is 5?
To prove that mass is conserved during a chemical change, a chemical equation must be balanced, meaning it has the exact same number of these on both sides of the arrow.
What are atoms?
What is the force of an object that has a mass of 10kg that is accelerating 5 m/s2?
What is 50?
If you turn up the volume on your radio, you aren't changing the sound wave's frequency or wavelength; instead, you are increasing this property, which measures the wave's height and energy.
What is amplitude?
Discovered in 2012 by the Large Hadron Collider, this elementary particle in the Standard Model is responsible for giving all other particles their mass via its namesake "field."
What is the Higgs boson?
