For biology, our teacher gave us an asingment in which we had to prepare a model of the urinary system together with the functions of the organs that take place on it. We worked in pairs and I did this with Luz Esteban. Here I leave a picture of the model and our work;
Solid: Well what we see in solid, is that all the molecules are all together like if they were tied up. When we higher the temperature we saw that they start to get all together until you reach 535 K they start to separate. Then when we cool the temperature the molecules stop moving.
Liquid: This state is present when water is at a warm and normal temperature, this means, that is neither hot or cold. The water molecules, although they aren’t either all spread nor all closely together, have the force to be relatively close.
Gas: This state is made up when the temperature increase. This cause that the molecules start moving faster.
This is what I know about variation + Natural selection (ch19) Multiple choice test.
