The Periodic Table
The lightest and most abundant element in the universe, occupying the very first spot on the Periodic Table and represented by the symbol 'H'.
What is Hydrogen?
What are reactants?
This physics term is defined as the rate at which an object changes its velocity over time.
What is acceleration?
This scientific term describes the measure of the average kinetic energy of the particles in a substance, commonly measured in degrees Celsius or Fahreheit.
What is temperature?
This physics term is defined as the amount of force applied perpendicular to the surface of an object per unit area.
What is pressure?
The term used to describe the vertical columns on the periodic table where elements share similar chemical properties and valence electron counts.
Written on the right side of the arrow, these are the final substances formed as a result of a chemical reaction.
What are products?
In the International System of Units, this is the standard unit used to measure acceleration.
What is meters per second squared?
Unlike temperature, this form of energy is defined as the total thermal energy that transfers from a hotter object to a cooler object.
What is heat?
According to the Kinetic Molecular Theory, gas pressure inside a closed container is directly caused by this specific action of gas molecules.
What are collisions with the container walls?
The family name if the extremely stable, unreactive elements found in Group 18 on the far right side of the periodic table.
What are the Noble Gases?
To satisfy the Law of Conservation of Mass, these full-sized numbers are placed in front of chemical formulas to balance an equation.
What are coefficients?
This specific type of acceleration occurs when an object is slowing down, meaning its velocity is decreasing over time.
What is deceleration?
This is the specific term for the method of heat transfer that occurs through direct contact between solids, like a metal spoon heating up in a hot bowl of soup.
What is conduction?
Because the density of water is much higher than air, a driver experiences an increase of approximately 1 additional atmosphere of hydrostatic pressure for every this many meters of depth.
What is 33 feet?
This physical dimension of an atom generally decreases as you move from left to right across a single period due to a stronger pull from the nucleus.
What is Atomic Radius?
This specific type of chemical reaction always involves a substance reacting with oxygen gas, typically releasing a large amount of energy in the form of light and heat.
What is a combustion reaction?
According to Newton's Second Law of Motion(F=ma), if you double the net force applied to an object while keeping its mass constant, this happens to its acceleration.
What is it doubles? (or increases by two times)
This specific type of heat transfer occurs through the movement of fluids, where warmer, less dense material rises and cooler, denser material sinks.
What is convection?
If a person standing on two feet suddenly lift one foot to stand on just one leg, this happens to the total pressure they exert on the ground.
What is it doubles?
The far-sighted Russian chemist who published the first widely recognized periodic table in 1869 and successfully predicted the properties of undiscovered elements.
What is 2?
If a car starts from rest(0 m/s) and accelerates uniformly at a rate of 4 m/s^2, this will be its final velocity after exactly 5 seconds.
What is 20 meters per second? (or 20 m/s)
If you mix 100 grams of water at 20 degrees Celsius with 100 grams of water at 80 degrees Celsius, this will be the final equilibrium temperature of the mixture, assuming no heat is lost to the surroundings.
What is 50 degrees Celsius?
To avoid sinking into deep snow, people wear snowshoes. This works because the wide shoes increase the surface area, which causes this to happen to the pressure exerted on the snow.
What is it decreases?
