Properties of Matter
In this state of matter, particles can easily slide past one another.
What is liquid?
In an atom, protons and neutrons are found here.
What is the nucleus?
Ripping up a piece of paper is an example of this kind of change.
What is a physical change?
This is the rate of change of distance over time.
What is speed?
This is known as stored energy.
What is potential energy?
The measurement of the average kinetic energy of particles in a substance.
What is temperature?
These are negatively charged subatomic particles.
What are electrons?
There are 4 indicators of chemical change: color change, new gas formed, new solid formed, and this.
What is release or absorption of energy?
The slope of a position-time graph.
What is velocity?
Energy cannot be created nor destroyed.
What is the law of conservation of energy?
The ratio of mass to volume of a given substance.
What is density?
This family of elements has a full valence shell.
What are the noble gases?
By crushing Alka Seltzer, we increase the rate of chemical reaction by increasing this factor.
What is surface area?
A quantity that has both magnitude and direction.
What is a vector quantity?
This is the net force acting on a stationary object.
What is zero?
The density of 1 kg block of aluminum is 2.7 g/cm3. This is the density of a 2 kg block of aluminum.
What is 2.7 g/cm3?
What are ions?
Compounds are breaking apart and new compounds are being formed in this kind of change.
What is a chemical change?
The most direct path from start to finish.
What is displacement?
The same net force is being applied to two different objects. This factor will determine which object will accelerate faster.
What is mass?
On a heating or cooling curve, this occurs when the temperature plateaus (doesn't change).
What is a phase change?
An atom with 8 protons is likely to form an ion with this electric charge.
What is a -2 ion?
This chemical bond occurs when electrons are transferred from one atom to another atom.
What is an ionic bond?
An airplane taking off the runway experiences this type of motion.
What is positive acceleration?
The weight of a 45 kg person on Earth.
What is 441 Newtons?
