Solids, Liquids, and Gases

What is Charles's Law?

• The force pushing on a surface divided by the area of that surface

• A principle that describes the relationship between the temperature and volume of a gas at constant pressure

• A change directly from a gaseous state to solid without becoming a liquid.

• A principle that describes the relationship between the pressure and volume of a gas at constant temperature

What are the three states of matter we learn about?

• Liquid

• Solid

• Fire

• Gas

• Wind

Jam has a definite shape and volume. Which classification best describes the jam?

• Amorphous Solid

• Crystalline Solid

• Liquid with high viscosity

• Liquid with low viscosity

10. Particles in this state of matter are close together and can slide around one another. They move at a medium speed with medium energy.

Chelsea went ice-skating. The ice, her skates, the Zamboni, and the rink building itself were all examples of solids she encountered. She developed a model of the particles in the ice. Which of these statements about the particles present in her model of a solid are true? Choose the three statements that apply.

• They vibrate in place.

• They slide past each other.

• They are packed very closely together.

• They cause the solid to have definite volume and definite shape.

• They move quickly and spread out away from each other.

Many technologies use enclosed fluids. For example, a hydraulic press at an auto repair shop uses trapped water to lift heavy cars. Hot-air balloons heat trapped air to lift a basketful of people. Look at the two diagrams that model fluid particles. Which statement best identifies which of these models represents a gas?

• Diagram B is a gas, because its particles move more slowly and are farther apart.

• Diagram A is a gas, because its particles move more slowly and are closer together.

• Diagram B is a gas, because its particles move more quickly and are farther apart.

• Diagram A is a gas, because its particles move more quickly and are closer together.

Bela made scrambled eggs while camping. She placed the eggs in a pan on the grill, then turned on the flame to apply heat to the pan and to the eggs. By applying heat, Bela increased the _______________ of the eggs. She

could measure how much the _______________ increased with a thermometer.

• potential energy, temperature

• thermal energy, temperature

• temperature, thermal energy

• thermal energy, mass

Michael’s car ran over a nail, which made a hole in one of the tires. At what point will air stop pouring out of the hole in the tire?

• When all of the air has escaped from the tire

• When the air pressure in the tire is less than atmospheric pressure

• When the air pressure in the tire is equal to atmospheric pressure.

• When the air pressure in the tire is greater than atmospheric

  pressure.

Kenneth warmed up a 100-mL sample of air in an expandable container. He displayed the results in the following graph. The results formed a straight line, so he extended the line the full length of the graph.

At what temperature did the gas have a volume of 110 mL?

• 19 K

• 20 K

• 110 K

• 300 K

What is Boyle's Law?

• The force pushing on a surface divided by the area of that surface.

• A principle that describes the relationship between the temperature and volume of gas at constant pressure.

• Maintaining consistency between two variables.

• A principle that describes the relationship between the pressure and volume of gas at constant temperature.
