Q. What is the root mean square speed of gas molecules at a temperature T? (2021)
A.
√(3RT/M)
B.
√(RT/M)
C.
√(2RT/M)
D.
√(3kT/m)
Solution
The root mean square speed (v_rms) of gas molecules is given by the formula v_rms = √(3RT/M), where R is the universal gas constant, T is the temperature, and M is the molar mass.
Q. What is the root mean square speed of gas molecules at temperature T?
A.
(3RT/M)^0.5
B.
(RT/M)^0.5
C.
(2RT/M)^0.5
D.
(RT/3M)^0.5
Solution
The root mean square speed (v_rms) is given by the formula v_rms = (3RT/M)^0.5, where R is the gas constant, T is the temperature, and M is the molar mass.
Q. What is the root mean square speed of gas molecules directly proportional to?
A.
The square root of the temperature.
B.
The square of the temperature.
C.
The mass of the gas molecules.
D.
The volume of the gas.
Solution
The root mean square speed of gas molecules is directly proportional to the square root of the absolute temperature, as given by the equation v_rms = sqrt(3kT/m).
Correct Answer:
A
— The square root of the temperature.
Q. What is the root mean square speed of gas molecules in a container at temperature T?
A.
sqrt(3kT/m)
B.
sqrt(2kT/m)
C.
sqrt(kT/m)
D.
sqrt(3RT/M)
Solution
The root mean square speed (v_rms) is given by the formula v_rms = sqrt(3kT/m) where k is the Boltzmann constant, T is the temperature, and m is the mass of a gas molecule.
Q. What is the root mean square speed of gas molecules in an ideal gas at temperature T?
A.
sqrt(3RT/M)
B.
sqrt(2RT/M)
C.
sqrt(RT/M)
D.
sqrt(3kT/m)
Solution
The root mean square speed (v_rms) is given by the formula v_rms = sqrt(3RT/M), where R is the gas constant, T is the temperature, and M is the molar mass.
Q. What is the rule for determining if a number is divisible by 11?
A.
The sum of the digits must be even
B.
The difference between the sum of the digits in odd positions and the sum of the digits in even positions must be divisible by 11
C.
It must end in 1
D.
It must be a prime number
Solution
A number is divisible by 11 if the difference between the sum of the digits in odd positions and the sum of the digits in even positions is divisible by 11.
Correct Answer:
B
— The difference between the sum of the digits in odd positions and the sum of the digits in even positions must be divisible by 11
Q. What is the rule for determining if a number is divisible by 7?
A.
The last digit must be 0
B.
Double the last digit and subtract it from the rest of the number
C.
The sum of the digits must be divisible by 7
D.
The number must end in 7
Solution
To check if a number is divisible by 7, you can double the last digit and subtract it from the rest of the number; if the result is divisible by 7, then the original number is as well.
Correct Answer:
B
— Double the last digit and subtract it from the rest of the number
