Question

15 multiple choice 1 point science according to the kinetic molecular theory, which statement explains why an ideal gas can be compressed to a smaller volume? the motion of the gas particles is circular and orderly. the force of attraction between the gas particles is strong. as the gas particles collide, the total energy of the system decreases. the gas particles are separated by great distances relative to their size.

Explanation:

• Kinetic molecular theory states gas particles are in constant random motion (not circular and orderly), so first option is wrong.
• Ideal gas particles have no (or negligible) attractive forces (not strong), so second option is wrong.
• In ideal gas collisions, total energy is conserved (doesn't decrease), so third option is wrong.
• Gas particles are far apart (separated by great distances relative to their size), allowing compression.

Answer:

The gas particles are separated by great distances relative to their size.
