Question 25

A student has a sealed cylinder containing helium gas at room temperature.

a.

Describe the arrangement, separation, and motion of the particles in the helium gas.

[3]
b.

The student heats the cylinder. State the effect, if any, of heating on the average kinetic energy of the particles in the gas.

[1]
c.

State the name of the temperature at which the particles of a gas would have the minimum possible kinetic energy.

[1]
d.

State the value of this temperature on the Celsius scale. Include the unit.
