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: Collision theory states that chemical reactions occur when atoms, ions, or molecules collide.

Output: What states that chemical reactions occur when atoms, ions, or molecules collide?


Input: Consider Input: Collision frequency is greater for homogeneous category of catalysts, which also tend to be more sensitive to temperature and more 'expensive'.
Output: Collision frequency is greater for what category of catalysts, which also tend to be more sensitive to temperature and more 'expensive'?
