Chemical Interactions Investigation 4

A student put room-temperature water into a bottle. She pushed the a stopper and tube into the bottle until the water came halfway up the tube. The student turned the bottle system sideways and put a cold wrap around the bottle for 2 minutes. She then put a hot wrap around the bottle. What caused the water level in the tube to change when the student put the hot wrap on the bottle? Which statement is false?

• Take up more space, and move farther out in the tube.

• Particles begin to collide more, causing the liquid to expand.

• The hot wrap transfers energy to the water in the bottle, and as the kinetic energy of the water particles increase.

• The particles begin to boil, and steam

What is the difference between compression and contraction?

• Compression is when pressure is applied to a material, or substance. Contraction is the result of decrease Kinetic Energy of the particles in the material.

• Compression is when particles thrown out of the way, and Contraction is when you pull the particles apart.

• Compression is when you make rocks out of particles, and contraction is when the particles are smashed together.

• Compression is when you use pressure to make the particles stick together. Contraction is when the particles are cracking.

A welder heats up a strip of steel, and bend it to fit over a cargo pallet. The welder then let the strip cool down. When the strip is heated the particles are

• Bouncing around, decrease in numbers.

• Running away,

  increase in numbers

• Moving farther apart

  Move faster

• Start moving

  Get closer

What happens when the strips cool?

• Increases and the particles move farther apart

• Decreases and the particles move more slowly

• Decreases until the particles stop moving

• Does not change

A student put a cap on a bottle, trapping room-temperature air inside. He put the bottle in the freezer for 15 minutes, then took it out and saw that the bottle looked different. What caused the bottle to change shape?

• Some of the air particles got out of the bottle.

• The air particles in the bottle got closer together.

• The air particles settled to the bottom of the bottle.

• The air particles cooled and become smaller.

What happens to the particles in the syringe when you push on the plunger?

• The particles in syringe move closer together.

• The particles in the syringe move farther apart

• The particles escape the syringe

• The particles did not move.
