Water vapor is a colorless gas that is impossible to see. _________________________
True
100
The common state of matter that does not have a definite shape or a definite volume is a(n) ____________________.
What is a gas
100
The change from liquid to solid, or the reverse of melting, is called
What is Freezing

Suppose you buy some inflated party balloons that are at room temperature (about 20°C). What will happen to those balloons if you take them outside on a cold day? Explain.
The balloons will decrease in volume. When the temperature of a gas at constant pressure decreases, its volume also decreases. Because the balloon is flexible, it contracts.
200
The resistance of a liquid to flowing is its a. pressure. b. temperature. c. viscosity. d. volume.
What is C, Viscosity
200
Particles in a liquid move around just as freely as particles in a solid. _________________________
False, more freely than
200
The resistance of a liquid to flowing is called ____________________.
What is viscosity
200
When a solid turns directly into a gas
What is sublimation
200
Explain how the motion of particles differs in gases, liquids, and solids.
Gas particles are spread far apart, and they move in all directions at high speeds, filling all the space available to them. Liquid particles are packed closely together, but they can move freely around one another. As a result, a liquid can take on the shape of its container. Solid particles are packed tightly together; they can vibrate but not move from their fixed positions.
300
Particles of a liquid a. are tightly packed together and stay in a fixed position. b. have no viscosity. c. decrease in volume with increasing temperature. d. are free to move in a container but remain in close contact with one another.
What is D. are free to move in a container but remain in close contact with one another.
300
At its boiling temperature, the particles of a liquid are moving so slowly that they begin to form regular patterns. _________________________
False, freezing
300
Salt, sugar, and snow are examples of ____________________ solids.
What is crystalline
300
The surface of water can act like a sort of skin due to a property of liquids called
What is surface tension
400
In which state of matter do the particles spread apart and fill all the space available to them? a. crystal b. liquid c. gas d. solid
What is C:Gas
400
In crystalline solids, the particles are not arranged in a regular pattern. _________________________
False, amorphous
400
A shrinking puddle is an example of ____________________, or vaporization that takes place only on the surface of a liquid.
What is evaporation

when the temperature of a gas increases at constant pressure, its volume increases is known as what law
What is Charles' Law
500
The force of a gas’s outward push divided by the area of the walls of the container is the gas’s a. volume. b. temperature. c. pressure. d. density.
What is C Pressure
500
The type of graph that results when the volume of a gas is measured as its pressure is changed (at constant temperature) is a straight line. _________________________
False, Curve
500
