Okay kiddo, have you ever seen a cake being baked in the oven? When we bake a cake or cookies, we put the batter inside the oven and turn on the heat. After some time, the cake becomes fluffy and brown, and you can smell the yummy flavors that are coming out of the oven. Do you know why that happens?
That happens because of a process called 'thermochemical reaction'. It means that when we heat something, its molecular structure changes, and new molecules are formed. Similarly, scientists use a special machine called 'thermal and evolved gas analyzer' to study the chemical composition of different things.
For example, imagine we have a rock, and we want to know what it's made of. We put the rock into the thermal and evolved gas analyzer, and it heats up. As it gets hot, different gases are released from the rock, and the machine analyzes them to figure out what the rock is made of.
The machine works like a nose, sniffing the gases that are coming out of the substance and identifying them. Just like we can smell the yummy cake smells coming out of the oven, the machine can smell different gases coming out of a rock or any other substance.
Scientists use the thermal and evolved gas analyzer to study all sorts of things, from rocks on other planets to the gases coming out of a volcano or a chemical reaction in a lab. This machine is very helpful in understanding the chemistry of different things and can help us make new discoveries about our world.
So, in short, the thermal and evolved gas analyzer is like a nose that smells the gases coming out of a substance when it's heated up, and it helps scientists figure out what the substance is made of.
