Heat and temperature are related, but they are not the same thing. Heat is a form of energy called thermal energy. Objects are composed of molecules, which move around.
When molecules gain energy, they move even more. Every object on Earth has thermal
energy. That's because even the molecules inside very cold objects are not perfectly still,
Temperature is a measure of the intensity of an object's thermal energy. It tells us the
average amount of thermal energy an object has. This is why a small hot object can have a
higher temperature but less thermal energy than a large cold object.
Based on the passage, an object with a lot of thermal energy
А
might be cold but very small
B
might be cold but very large.
is always large
is always small.

To quote the passage: "...a small hot object can have a

higher temperature but less thermal energy than a large cold object."

In other words, a small object can have a high average thermal energy, and therefore a high temperature, but since the object is smaller, the magnitude of thermal energy present in the object is by default less than that in the larger object.  As the passage indicates, every object has thermal energy.  So, despite the fact that the larger object is colder, it still has a greater thermal energy due to the number of molecules that comprise the larger object.

Based on the passage, an object with a lot of thermal energy might be cold but very large.

- "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)."
