Physical Properties 1
Peanut brittle that breaks apart very easily is a great example of this physical property.
What is brittleness?
The chemical property of how well one substance will react with another substance is called this.
What is reactivity?
This physical property and phase change is the opposite of melting.
What is freezing?
This is how many mL there are in 45 L.
What is 45,000?
This is the terminal which was responsible for "liberating" the oxygen gas we collected in our electrolysis activity.
What was positive?
This is the reason why color and texture are physical properties.
What is they do not change the composition of a substance?
This is the type of gas that would form if baking soda was combined with vinegar.
What is carbon dioxide or CO2?
This physical property and phase change is the opposite of condensation.
What is evaporation?
These are the four letters (in order) that help us complete our metric conversions.
What is D-R-U-L?
This is the terminal which was responsible for "liberating" the hydrogen gas we collected in our electrolysis activity.
What was negative?
Aluminum foil is very much an example of this physical property. A solid block of aluminum may not be.
What is malleable?
This substance was used to help conduct electricity in water during one of our class activities.
What is salt or NaCl?
On our Temperature and Energy/Phase Changes (Water) graph, this is the line segment that represents a gas condensing into a liquid.
What is ED?
This is how many dag there are in 35,000 mg.
What is 3.5?
This was a very horrific and historical lesson learned about the flammability of hydrogen gas. It happened in 1937... in New Jersey.
What was the Hindenburg disaster?
Placing sugar into very hot water and watching it dissolve is a great example of this physical property.
What is solubility?
On our "camping trip" on the TV screen, there was only one example of a chemical property (change) shown. This was what it was.
What was burning wood?
A super-heated gas is called this state (phase) of matter.
What is plasma?
One meter has this many dm in it.
This is specifically why we were able to collect twice as much hydrogen gas as we did oxygen gas.
What is because there is twice as much hydrogen in water as there is oxygen? Formula is H20.
This is the approximate density of Pittsburgh's most famous metal.
What is 7.6 g.cm3? (steel)
We separated water into hydrogen and oxygen gas using this chemical property-based process.
What is electrolysis?
This physical property and phase change is the opposite of deposition.
What is sublimation?
67 km is this many mm.
What is 67 million (67,000,000)?
This is the collected gas we specifically discussed in class that could possibly be used as rocket fuel.
What is hydrogen or H2?
