If the volume is constant and the temperature increases, the pressure
increases
If the pressure is constant and the temperature increases, the volume
increases
If temperature is constant and the pressure increases, the volume
decreases
The data points form a curve, showing that gas pressure is _________ proportional to the volume
inversly
The data points form a straight line, showing that the volume of a gas is _____ proportional to the temperature
directly
Why do truck drivers need to monitor and adjust tire pressure on long trips during the summer?
Because the tires can become very hot and as the temperature increases, so does the pressure of the air inside the tires. If the pressure becomes greater than the tires can hold, the tires will burst.
3 properties of a gas that you can measure are: temperature, volume and pressure. In order to study the relationship between 2 of these, what must be done to the 3rd
It must be kept constant
If a gas is at constant volume, what will happen to the pressure when the temperature decreases?
pressure increases
How does adding thermal energy affect a gas
It will get warmer and the pressure it exerts on its container, increases.
If you were to blow up a balloon indoors and then take it outdoors on a cold day, what would you observe?
It will contract and shrink
You have helium-filled balloon and you decide to heat it to see what would happen. Describe what you observe.
It will expand
Gas pressure is inversely proportional to volume at constant temperature. What does this mean?
As one increases, the other will increase at the same rate. The graph will show a curve.
If the sun shining through a window heats the air in a sealed room, what happens to the air pressure in that room?
It increases
The volume of a gas is directly proportional to its temperature (in Kelvin) at constant pressure. What does this mean?
As one increases, the other will increase at the same rate. The graph will show a straight line.
What effect does increasing pressure have on gas particles?
It pushes them close together.
Describe charl's law
When the temperature of a gas at constant pressure is increased, its volume increases, When the temperature of a gas at constant pressure is decreased, its volume decreases.
