Q. According to the kinetic theory, what happens to the pressure of a gas if the temperature is doubled while keeping the volume constant?
A.
Pressure remains the same
B.
Pressure doubles
C.
Pressure triples
D.
Pressure halves
Solution
According to the ideal gas law, if temperature is doubled and volume is constant, pressure also doubles.
Q. In the kinetic theory of gases, which of the following assumptions is NOT true?
A.
Gas molecules are in constant random motion
B.
Gas molecules occupy a negligible volume
C.
Gas molecules experience no intermolecular forces
D.
Gas molecules have significant mass
Solution
In the kinetic theory of gases, it is assumed that gas molecules occupy a negligible volume and have negligible mass compared to the volume they occupy.
Correct Answer:
D
— Gas molecules have significant mass
