keeping the temperature constant and increasing the container volume

Answer 1

The correct adjustment that would increase the speed of the particles is:

keeping the pressure constant and increasing the temperature.

Increasing the temperature of the particles increases their kinetic energy, which in turn increases their speed. Keeping the pressure constant while increasing the temperature allows for this increase in kinetic energy without changing the number of particles or the constraints on volume in a way that would limit their speed.
