June filled two ziploc bags with yeast, sugar, and flour. She put one in the fridge, she placed on a warmer in the kitchen. The bag in the fridge showed almost no change after 10min, but the bag on the warmer was swollen with white bubbles. What type of change was she observing?
What is a CHEMICAL CHANGE
100
A combination of matter that can be seperated
What is a mixture.
100
This is the most basic form of matter

Bob poured one cup of rock salt into room temperature water and left it. Then he poured one cup of table salt into room temperature water and left it. The table salt dissolved more quickly. What factor caused this to happen? EXPLAIN
What is PARTICLE SIZE. When the matter being dissolved is the same, the matter with smaller particles will dissolve more quickly. *** The temperature must also be the same

What is D. Shaking
200
What is formed when many of one type of atom clings together?
What is an ELEMENT.

Luke poured one tablespoon of sugar into a cup of warm water and left it. He poured one tablespoon of sugar into another cup of warm water water and stirred it. Both dissolved, but the sugar that was stirred dissolved more quickly. What factor caused this to happen? Explain.
What is MOVEMENT. When the matter being dissolved is the same, and the temperature is the same, then an increase in movement (such as stirring or shaking), will speed up the rate of dissolving.
300
Which of these is NOT a physical property of matter? a. its mass b. its volume c. it's temperature d. it's ability to burn.
What is d. it's ability to burn
300
Is salt water an example of a mixture or a solution? Explain why.
What is a MIXTURE. This is because evaporation can be used to seperate salt from water.
300
What is formed when two or more types of atom combine?
What is a compound or molecult.
300
Particles flow closely over each other.
What is a liquid
400
When matter increases in temperature, the particles will move more quickly. Which can be an effect of an increase in temperatre. a. particles of matter condensing b. particles of matter boiling c. particles of matter freezing d. particles of matter mixing
What is b. particles of matter boiling.
400
Which is an example of a physical change? a. melting ice b. burning a candle c. popping corn d. toasting bread
What is a. melting ice
400
This is formed when one type of matter dissolves into another type of matter.
What is a SOLUTION
400
Water is a combination of two Hydrogen particles and one oxygen particle, therefore water is a __________________.
What is a compound.
400
This physical change quickly changes a liquid to a gas.
What is boiling.
500
Which option is not an example of how temperature affects a chemical or physical change? a. Baking a cake in an oven b. Mixing pancake batter in a kitchen c. Freezing water in a freezer d. Milk spoiling on a kitchen counter
What is b. Mixing pancake batter in a kitchen.

What is a solution.
500
Which of these has the greatest effect on how matter can change? a. shape of matter. b. temperature of matter. c. the mixture of matter.
What is b. the TEMPERATURE of matter.
500
