Which of these statements is not necessarily true for two objects in thermal equilibrium? The objects' temperatures are not changing. The objects are made of tiny particles that are moving at the same rate. The objects' temperatures have both changed by the same amount. The objects have the same temperature.

h let me think

- "the choice that is not an indicator of a chemical change is "state of matter changes". more common than not, chemical reactions produce energy in the form of light or heat. along with energy, they also produce a new substance called the product that could be in any state of matter (solid, gas, or liquid)."

8 m/s because for him to get the same amount of energy as ray is putting out, bobby, who weighs half as much as ray, needs to run twice as fast.
