Riddle: I give you a group of three. One is sitting down, and will never get up. The second eats as much as is given to him, yet is always hungry. The third goes away and never returns.
The stove, which is usually located in kitchens for purposes such as cooking and heating, always stands in the same place, so it never gets up, it always sits. Fire, on the other hand, is a rapid combustion event that mostly burns.
The more you throw something into the fire, the more it burns, so the fire is always hungry, it eats whatever you give. Lastly, smoke is a gas that is released by the combustion of a substance. Smoke is a gas that is released by the combustion of a substance. The answer of this riddle is stove, fire and smoke.
Answer: Stove, fire, and smoke.
