#1
Which gas law describes the relationship between pressure, volume, and temperature of a gas?
Charles's law
ExplanationVolume and temperature of a gas are directly proportional at constant pressure.
#2
What happens to the pressure of a gas if its volume is decreased while keeping the temperature constant?
Pressure increases
ExplanationPressure rises when gas volume decreases at constant temperature.
#3
What is the unit of pressure in the International System of Units (SI)?
Pascal (Pa)
ExplanationStandard unit for measuring pressure.
#4
What is the SI unit of temperature?
Kelvin (K)
ExplanationStandard unit for measuring temperature.
#5
What is Boyle's law?
The volume of a gas is inversely proportional to its pressure, at constant temperature.
ExplanationVolume and pressure of a gas vary inversely when temperature remains constant.
#6
What is the ideal gas law equation?
PV = nRT
ExplanationExpresses the relationship between pressure, volume, amount of gas, and temperature.
#7
Which gas law states that the volume of a given amount of gas held at constant temperature is directly proportional to the pressure?
Boyle's law
ExplanationVolume of gas varies directly with pressure at constant temperature.
#8
What is the term for the temperature at which a gas becomes a liquid?
Critical temperature
ExplanationTemperature above which a gas cannot be liquefied regardless of pressure.
#9
Which of the following statements regarding real gases is true?
Real gases deviate from ideal behavior at high pressures and low temperatures.
ExplanationReal gases behave differently from ideal gases under extreme conditions.
#10
Which of the following gases has the highest average kinetic energy at the same temperature?
Helium (He)
ExplanationHelium molecules move fastest on average at a given temperature.
#11
What is the term for the temperature at which a gas occupies no volume and generates no pressure?
Absolute zero
ExplanationThe lowest possible temperature at which molecular motion ceases.
