Given scientific fact as input, generate the question from this fact such that it can be answered from the input.

Input: Consider Input: Electric motors transform electrical energy into kinetic energy.

Output: Electric motors transform electrical energy into what other form of energy?


Input: Consider Input: Metabolism produces waste energy in the form of heat, which helps warm-blooded (endotherm) animals conserve and maintain heat at a relatively constant body temperature.

Output: Metabolism produces waste energy in the form of heat, which helps what type of animal conserve and maintain heat at a relatively constant body temperature?


Input: Consider Input: When volume does not change, temperature is proportional to pressure.
Output: When volume does not change, temperature is proportional to what other property?
