One grape is placed in tap water and another grape is placed in salt water. The change in their mass is measured after a day. List one variable that should be kept constant in order to have a controlled experiment.
Amount of water, environment, etc.

What is the movement of particles from areas of high concentration to low concentration.
Diffusion.

In which state of matter do particles contain the most potential energy?
Gas because they are spread the furthest apart.

Why do bridges need expansion joints?
To expand and contract with hot and cold weather to prevent the bridge from collapsing.

When a liquid is boiling and turns to a gas, the potential energy ______________(inc. / dec. / stays the same), the attractive forces holding the particles together _______________ (inc. / dec. / stays the same), and the kinetic energy _______________ (inc. / dec. / stays the same).
1. increases
2. decreases
3. stays the same

What is temperature and how is it measured?
1. The average kinetic energy of the particles that make up a substance.
2. Thermal expansion and thermal contraction.

Explain why the graph plateaus and temperature stays the same when ice is changing states from solid ice to liquid water.
Eventually the particle in the ice gain so much kinetic energy that they are forced to change states. When this happens, the heat energy being added goes towards breaking bonds between particles and increasing potential energy. Therefore, kinetic energy stays the same and temperature does not change.

Wade could tell it was the night before trash pickup. The garbage can smelled terrible! What was it about summer that made the trash smell so bad, but the odor was not bad during the winter months? Construct an explanation that details the role particle energy plays in smell.
thermal expansion causes the particles to spread out making it more likely that you will smell them.

Find the average temperature for the time it took for the ice to melt. What does this number represent?
o min = 0 C
1 min = 0 C
2 min = 1 C
3 min = 1 C
4 min = 2 C
5 min = 2 C
1.2 C = Melting point of water

A student left their soup on the counter and it cooled to room temperature. They could add 100 mL of warm water OR 20 mL of hot water. Describe the option is best for heating the soup and explain why.
The student should use the 100 mL of warm water because the more particles you have, the greater the mass, which means more total kinetic energy.

Why do you need rock salt to make ice cream?
It lowers the freezing point of the ice in the bag creating a cooler environment. The salt forces the ice to melt. When something melts, it takes heat away from the environment making it cooler.

What is a symbiotic mutualistic relationship?
Both species benefit from each other. Example: clown fish and sea anenome.
