Question
1) The absolute temperature of an ideal gas is directly proportional to which of the following?A) kinetic energy
B) speed
C) mass
D) momentum
2) Oxygen molecules are 16 times more massive then hydrogen molecules. At a given temperature, the average molecular kinetic energy of oxygen, compared to hydrogen
A)is greater.
B) is less.
C) is the same.
D) more data is required to answer correctly
Explanation / Answer
1>>A) kinetic energy 2>>C) is same explanation : average velocity = squareroot(3kTM) velocity^2=3kT/M T is temperature so when you bring M to other side M x velocity ^2 = 3 k T k-some constant so temperature is dependant on Kinetic energy ##explanation for first part second case: option C is correct because T in above relation is independent of Molecular mass
