What is the final step of the following process: - A fuel is heated in an oven - Above the oven is a tank of water that is sealed - The tank of water begins to boil above the oven - A the water boils steam is created - The steam is denser than air so it needs a place to go - The steam is forced out of the tank and into a piston - The piston moves up - The valve of the piston closes - The valve on the next piston opens
----
Answer: The steam fills the next piston, driving it up, and the other one down

Q: What is the final step of the following process: - Aluminium cans are put into a recycling bin - Aluminium cans are then collected and taken to a treatment plant - At the treatment plant the aluminium is sorted and cleaned - Readied for reprocessing - The aluminum cans go through a re-melt process - Turned into molten aluminium - The molten aluminum is made into large blocks called ingots - The ingots are sent to mills and are rolled out into thin sheets
A: The rolls are ready to be made into new aluminum products.

Question: What is the final step of the following process: - Sunlight passes through the glass into the greenhouse - The plants and floor absorb the the sunlight - The absorbed sunlight is converted to heat - The heat cannot escape the glass - The heat is trapped in the greenhouse - The hot air rises - The colder air at the top is pushed to the bottom
Answer: The colder air is then warmed by the floor and the plants.

[Q]: What is the final step of the following process: - The organism must die to begin the process - The soft tissue decomposes - The bones are left behind - Scavengers tear the body apart and move the bones elsewhere - Wind and rain also scatter the bones further - The bones left behind will weather and become buried by sand and soil - The proteins in the bone are replaced with minerals that are dissolved in the soil - This creates a rock-like substance called a fossil - Water and wind erosion wear away the layers of soil on top of the fossil
****
[A]: This makes discovery of the fossil possible.

input: Please answer the following: What is the final step of the following process: - A machine called a pulverizer grinds the coal into a fine powder - The coal powder mixes with hot air, which helps the coal burn more efficiently, and the mixture moves to the furnace - The burning coal heats water in a boiler, creating steam - Steam released from the boiler powers an engine called a turbine, transforming heat energy from burning coal into mechanical energy that spins the turbine engine - The spinning turbine is used to power a generator, a machine that turns mechanical energy into electric energy - This happens when magnets inside a copper coil in the generator spin - A condenser cools the steam moving through the turbine - As the steam is condensed, it turns back into water
++++++++++
output: The water returns to the boiler, and the cycle begins again

What is the final step of the following process: - Water in the clouds becomes very cold - The cold water forms ice crystals - The ice crystals grow by absorbing surrounding water droplets - Form snowflakes
----
Answer:
The snowflakes fall to the ground.
