___________, ____________ and _____________ are the 3 states of matter
What are solids, liquids and gases?

Do we know everything about matter? Explain
No we do not, because even through human visuals and the aid of technology, the tiniest little details can still be unnoticed.

The density of 10 karat gold is 11.4 grams/centimeters cubed. Jamie wants to find the density for his 10 karat gold ring. Identify a method that can be used can be used to help Jamie out.
Displacement can be used: When you put the ring in a graduated cylinder filled with water, the water level rises. Jamie will have to calculate the new measure of water in the graduated cylinder and then subtract it with the previous measure without the ring. Then after finding the volume, he will have to weigh it to figure out the mass. After this, he must simply divide the mass with the volume to figure out the density.

_________, ____________, ___________, ___________, and ____________ are physical properties.
What is color, ductility, malleability, density, boiling point, melting point, conductivity, crystalline structure, brittleness, magnetism, solubility,viscosity, hardness, state, or lustre?

Physical changes are when ___________ and chemicals are when ____________.
When matter changes state, but the substance stays the same, and the process is reversible. When matter changes state, and gives away or absorbs energy, and a new substance is usually created.

The 5 points of the Kinetic Molecular Theory are ___________________________________________________________________________________________________________________________________________________
-All matter made up of tiny particles -Different substances have different particles -The particles are in constant motion -The more energy the particles have, the faster they move -The attraction between particles decrease with an increase in distance

Describe the type of motion in liquids
Particles still vibrate, but can now move past one another, can bump into each other and the sides of their container.

Why are diamonds used as a coating for drill bits used by dentists?
This is because diamonds are the hardest stone known to mankind, due to their triangular carbon structure.

________ are the simplest form of Matter & they contain only 1 kind of particle and ________ is another pure substance that consists of 2 or more Elements. __________ are mixtures that can be distinguished by the naked eye and _________ are evenly and microscopically distributed.
What are Elements & Compounds? What are heterogeneous and homogeneous mixtures?

Flammability and Corrosion have ____________ in common and their differences are ____________.
Reacts with oxygen and chemical property for common behavior and slow reacting(corrosion) and fast reacting(flammability) and corrosion takes place on certain metals while flammability takes place with anything that can catch on fire?

When a piece of paper burns, a chemical change takes place. Give 3 pieces of evidence that supports this point.
1. Reacts with Oxygen & gives off energy 2. A new substance is created (ash) 3. The process cannot be reversed
400
When sugar is dissolved in hot water, the density ________ because ________________________________________.
What is the increase of density? It happens because now there are more particles in the solution due to the sugar particles slipping between the H2O particles

(These measurements might not be exact) Coca Cola has 150 calories in one can and Brisk has 100 calories in one can. Imagine if they had the same volume, which one would sink in first or be beneath the other can, in swimming pool with the depth of 20 m.
The Coca Cola can would sink or be beneath the brisk can because it contains more calories, hence having a greater mass.
500
At _______, the physical properties of some of the metal elements like copper, zinc, silver and gold were understood but none of these were recognized as elements because of ________________________________________________________________________.
What is 1,000 BCE and the reason why they couldn't recognize these elements was because they did not have the technology that we have today & also because their beliefs were more religious than scientific. ( We don't care about jeopardy format, this is meant for scientific purposes )

When limestone caves react with ___________ chemically changes ___________ to ____________ and soluble substances.
What is groundwater that is slightly acidic, limestone and carbon dioxide?

A mixture of sand, salt, water, leaves and iron shavings are in water. State all the different ways to isolate each specimen.
-Hand pick the leaves -Take a magnet and attract the iron shavings -Filter the sand through a sieve from the water and salt solution - Evaporate the water until salt is left behind
500
When there is compressed gas in a container and the container is heated, do the gas particles move faster or slower?
The gas particles slow down because when they are heated, they start moving faster & eventually bump into each other more frequently. This causes them to slow down.

Calculate the dimensions of this 3d shape and find to find the volume. if the mass is 330 grams, what is the density?
330 divided by 40 = 8.25 The answer is 8.25 grams per cm cubed
