Physical Properties 2
This is what would happen if you dropped a copper penny into a cup of water.
What is it would sink?
This is the chemical name of vinegar.
What is acetic acid?
On our Temperature and Energy/Phase Changes (Water) graph, this is the line segment that represents the phase change of evaporation.
What is DE?
100 hectometers would be this many meters.
What is 10,000?
This is the battery terminal that helped liberate the oxygen gas.
What is positive?
This physical property is defined as how much matter (mass) takes up how much space (volume).
What is density?
This is the chemical name for rust.
What is iron oxide?
On our Temperature and Energy/Phase Changes (Water) graph, this is the line segment that represents a liquid freezing into a solid.
What is CB?
Seventeen two-liter bottles of soda would be this many cL?
What is 3400?
This is what the word "lysis" literally means.
What is cutting?
These two words mean the same thing, how light is reflected off the surface of an object.
What are luster and shine?
This metal and this gas can be used to make salt. The kind of salt we use on our food.
What is sodium and chlorine?
Dry ice is actually this gas but in its solid state of matter.
What is carbon dioxide or CO2?
Five thousand (5,000) mm is this many meters.
What is five (5)?
This chemical property permitted us to light and burn hydrogen gas. It is not "burning."
What is flammability?
This is the term used to describe a material that is very good at conducting electricity.
What is a conductor?
The breakdown of an atom's nucleus, also known as nuclear decay, is called this chemical property.
What is radioactivity?
This state of matter is skipped when a substance sublimates.
What is liquid?
Two (2) millimeters is this many meters.
What is .002?
We saw several different things happen when we lit the collected hydrogen gas with our four different class groups. These are two different observations of them.
What is a pop?
What is a small flame?
What is a circular flame?
Similar answers?
This unique property of water will permit it to float when it is frozen. This is not normal. Normally solid things sink.
What is it becomes less dense?
Baking soda is also known as this. This is its chemical name.
What is sodium bicarbonate?
This physical property and phase change is the opposite of sublimation.
What is deposition?
This is how many meters there are in 7.5 million (7,500,000) millimeters.
What is 7,500?
This is the complete and balanced chemical equation for electrolysis.
What is 2H2O + electricity --> 2H2 + O2 ?
