Question

using the picture below, which of the following best describes the change in the particles from before to after? b before after a. as was added b. water was added c. thermal energy was added d. particles were added

Explanation:

The particles change from a more ordered, closely - packed state (likely a solid or liquid) to a more spread - out, disordered state. Adding thermal energy increases the kinetic energy of particles, causing them to move more freely and spread out, which is consistent with the change shown. Adding air, water, or more particles doesn't explain the change in particle arrangement and spacing as well as adding thermal energy does.

Answer:

C. Thermal energy was added
