440 oF
-223 oC
0 K
(a) measures the average kinetic energy of a sample of matter.
The (a) is a scientific theory that states that gases are composed of tiny particles that are in constant, continuous, random motion
The (a) temperature scale that sets its zero point at -273.15 degrees Celsius
The temperature at which a substance exists in both the liquid and solid forms is called the (a) .
The temperature at which the liquid and gas phase of a single substance are in equilibrium is called the (a) .
According to the kinetic molecular theory of gases, which statement is NOT true for all gases?
Gas particles are always moving.
All particles in a gas move at the same speed.
Gas particles collide with each other and with the walls of their container.
Gas particles move randomly and in straight lines.
Below is a graph showing degrees Celsius versus degrees Fahrenheit. Is their relationship proportional?
yes, because the graph is a straight line
no, because the graph does not contain the point (0,0)
Which relationship explains how a thermometer works?
As the temperature goes up, the volume of liquid inside the tube goes down.
As the temperature goes down, the volume of liquid inside the tube stays the same.
As the temperature goes up, the volume of liquid inside the tube goes up.
As the temperature goes down, the volume of liquid inside the tube goes up.
When the temperature of a gas decreases, what happens to its density?
increases, because the volume increases
decreases, because the number of particles increases
decreases, because the number of particles decreases
increases, because the volume decreases
Which is not an example of a physical change that takes place in the atmosphere?
Water vapor condenses to form a cloud.
A lightning strike forms ozone, O3, from oxygen gas.
The air pressure drops on a stormy day.
The air temperature increases as energy is absorbed from the Sun.
Low pressure systems are closely associated with cold and warm fronts. Low pressure systems are associated with
clear, sunny skies
clouds and precipitation
high pressure sytems
freezing cold weather
Suppose you have two gas samples in flexible containers with the same outside pressure and the same amount of gas in each. Sample A is at a temperature of 25 °C and Sample B is at 5 °C. Which of these statements is true?
Sample B has molecules moving at a greater average speed.
Sample A occupies a larger volume and has lower density.
Sample A has higher density and a smaller volume.
Sample A occupies a smaller volume and has molecules moving at a slower average speed
What is the volume of
15.0 g of ice?
13.8 mL
16.3 mL
15.0 mL
7.5 mL
For equal volume samples of snow, ice, and rain, which statement is correct in describing the mass of the samples?
The masses of each will be the same because in each case, the substance is water.
The mass of the rain will be largest because the rain has the highest density.
The mass of the ice will be smallest because the ice has the lowest density.
The mass of snow will be smallest because the snow has the highest density.
