The ____________ of molecules refers to how they move around relative to each other in a substance.
Freedom of movement
Which atoms make up a water molecule?
Two hydrogen atoms and one oxygen atom.
What is the measure of how hot or cold something is?
Temperature
________________________ is the energy that an object possesses due to its motion.
Kinetic Energy
How hot does it need to be to boil water?
212 degrees Fahrenheit
What term describes a pull between two molecules that remains the same for a substance?
Molecular Attraction
A ______________________ is a group of atoms joined together in a specific way.
Molecule
Explain how kinetic energy affects the phase change of a substance.
Kinetic energy affects the phase change of a substance because as the energy increases, it can cause the molecules to move more freely, potentially changing the substance from a solid to a liquid or a liquid to a gas.
Which of the following describes a group of atoms joined together in a particular way?
Molecule
The __________________ between molecules is a pull that is consistent for a particular substance.
Molecular Attraction
Describe what happens to molecular attraction when a substance changes from a solid to a liquid.
When a substance changes from a solid to a liquid, the molecular attraction decreases, allowing the molecules to move more freely and slide past each other, leading to a liquid state.
What is the relative size of things referred to as?
Scale
A __________________________ is a noticeably different form or state of the same substance.
Phase
Why is understanding the scale important when discussing phase changes?
Understanding the scale is important when discussing phase changes because it helps us comprehend the size and behavior of molecules during the transition between different states of matter.
What term is used to provide evidence that goes against a claim?
Refute
