Question 1
1 / -0

The total energy of molecules of a gas at a given temperature depends on the

A
number of gaseous molecules

B
volume of the gas

C
pressure of the gas

D
molar mass of the gas

Solution

The total energy of molecules of a gas at a given temperature depends on the number of gaseous molecules.
Question 2
1 / -0

For a fixed mass of an ideal gas at constant pressure, which of the following statements is true?

A
Plot of volume versus Celsius temperature is linear with a zero intercept.

B
Plot of volume versus Kelvin temperature is linear with a non-zero intercept.

C
Plot of V/T versus T is linear with a positive slope.

D
Plot of V/T versus T is linear with a zero slope.

Solution

According to Charles' law,

V/T = constant

Plot of V/T versus T will give a horizontal straight line with a zero slope.
Question 3
1 / -0

According to kinetic theory, what is true about collision between gas molecules and with the container, respectively?

A
They are perfectly inelastic; and impart momentum to container wall.

B
They are perfectly elastic; and impart momentum to container wall.

C
They are perfectly inelastic; and do not impart momentum to container wall.

D
They are perfectly elastic, and do not impart momentum to container wall.

Solution

According to kinetic theory, collision between gas molecules are perfectly elastic, and they impart momentum to container wall.
