Physical Properties of Matter
If something is melted, is that a physical or chemical change?
Physical
When heat is added to a solid, will the atoms/particles move faster or slower?
Faster
Matter cannot be created or destroyed.
The Law of Conservation of Mass
You need 10 grams of iron to react with 5 grams of oxygen to produce how much iron oxide?
15 grams
What can you use to record your data and observations?
A science notebook or computer
If a piece of paper is torn into pieces, is that a physical or chemical change?
physical change
What state of matter do atoms/particles move around the fastest and have the most space between each other?
Gas
When matter changes, its a physical or chemical change. Can I get rid of matter completely?
No
50 grams of Magnesium react with Oxygen. How many grams of Magnesium will be present after the reaction?
What is 50 grams
What step of the scientific method comes after the experiment?
Analyzing data
What state of matter do atoms/particles vibrate and have the least amount of space between each other? They are also organized.
Solid
What does the Law of Conservation of Mass state?
Matter cannot be created nor destroyed, only changed.
I have 3 grams of water, 6 grams of flour, and 9 grams of lemonade mix. I combine the water and the lemonade mix together. How many grams of lemonade do I now have?
12 grams
What do you do if your data from your experiment doesn't support your hypothesis?
Restart your experiment after making some changes.
Because the atoms/particles in this state of matter can slide past each, this state of matter can be poured.
Liquid
If baking soda and vinegar are combined together and some of the new substance releases a gas into the air, did matter get destroyed? Why or why not?
No, matter cannot be created or destroyed, just changed. The gas released is in the gas but still is matter.
If I combine 37 grams of vinegar with 17 grams of baking soda. How many grams of the new substance would I have after the reaction?
54 grams
What is an educated guess called?
Hypothesis
When making pancakes, all of the batter is used to make ten pancakes. What type of change just happened?
a chemical change
The atoms/particles in this state of matter spread out and fill their container.
Gas
