When heat is added to or is absorbed by a system, its internal energy increases. The amount of external work a system can do essentially refers to the amount of energy it can transfer to something else. So when internal energy increases, so does the external work done by the system.
friction creates heat. Largely heat, which comes from the external agent energy causing the friction. Also some possible rearrangement of the atomic/molecular structure of the surface, and the energy for that also comes from the external agent.
Heat flows from the hotter object to the colder object, unless there is some external process (such as a heat pump) which is transferring the heat in the opposite direction.
Heat pumps use a compressor to make the working fluid condense at a higher temperature.The compressor needs input energy.
Thermal energy because you are using heat. The thermal energy can be supplied by an external heat source or by electric it generating microwaves which excite the water molecules to produce heat.

The difference between an external stimulus and an internal stimulus is that an external stimulus is a stimulus that comes from outside an organism. But an internal stumulus is a stimulus that comes from inside an organism. An example for an external stimulus can be that when you are cold, you put on a jacket. An example for an internal stimulus is that when you feel hungry, you eat food.
External Stimulus
It is an external stimulus.
Tropisms is the response to an external stimulus in a specific direction.
The term for an involuntary reaction to an external stimulus is a reflex.
Tropism is the response plants have towards external stimulus.
An animal's immediate automatic response to an external stimulus will vary depending on the circumstance. When the external environment is stimulated there is a response that is triggered.
Tropism is the response plants have towards external stimulus.
