Heat energy is absorbed when boiling point comes
First, tell your teacher that the Sun is not at the center of the UNIVERSE. He observatory that occasionally planets would travel backwards in the night sky & people also observed the moons rotating around Jupiter to prove his theory.
Energy comes from making bonds in carbon dioxide and water.
Sorry I don’t understanddddd:/
The simple answer is that in a battery the chemical reactions that produce the electrical current are produced from materials that are already in the battery itself, whereas in a fuel cell, the reactants, almost always Hydrogen and Oxygen are fed to the cell like an external fuel.
. However, while a battery makes electricity from the energy it has stored inside the battery, a fuel cell makes its electricity from fuel in an external fuel tank This means that while a battery may run dead, a fuel cell will make electricity as long as fuel is supplied. For hydrogen fuel cells, hydrogen is the fuel and it's stored in a tank connected to the fuel cell. When hydrogen in the tank runs low, you refill it, or replace it with a full tank.
