Which of the following is a characteristic of gases?
They have a definite shape and volume.
They have no definite shape but have a definite volume.
They have no definite shape and no definite volume.
They have a fixed arrangement of molecules.
Which scientist discovered the inverse relationship between gas pressure and volume?
Jacques Charles
Robert Boyle
Lord Kelvin
Evangelista Torricelli
Boyle's Law states that pressure and volume of a gas are:
Directly proportional
Inversely proportional
Unrelated
Both increase at the same rate
What happens to gas pressure when the volume is reduced at constant temperature?
It increases
It decreases
It stays the same
It doubles
According to Charles's Law, as temperature increases, the volume of gas will:
Decrease
Increase
Stay the same
Turn into a liquid
What is the correct formula for converting Celsius to Kelvin?
K = °C + 273.15
K = °C - 273.15
K = 273.15 × °C
K = 273.15 / °C
What unit is commonly used to measure pressure?
Kelvin
Pascal
Gram
Liter
The force exerted by air molecules in Earth's atmosphere is known as:
Kinetic energy
Atmospheric pressure
Vapor pressure
Pascal's force
Who formulated the law that states the direct relationship between gas temperature and volume?
Jacques Charles
Robert Boyle
Lord Kelvin
Evangelista Torricelli
If a gas at constant pressure expands from 2 L to 4 L, what happens to its temperature?
It decreases
It increases
It remains the same
It turns into a liquid
When a gas is heated, its molecules:
Slow down
Stop moving
Move faster and spread apart
Move closer together
The kinetic molecular theory states that gas molecules move:
In a straight line until they collide
In a fixed, repeating pattern
Only when heated
Slowly and in place
A gas occupies 5.0 liters at a pressure of 2.0 atm. If the pressure is increased to 4.0 atm, what happens to the volume?
stay the same
decrease
increase
none
A balloon inflated inside a warm room appears slightly deflated when taken outside into cold weather. Which gas law explains this phenomenon?
Boyle's Law
Charles's Law
Pascal's Law
Newton's Law
Why do hot air balloons rise?
Cold air pushes the balloon up
The air inside contracts
The air inside expands and becomes less dense
The balloon material becomes lighter
