Explain why heating a full pot of soup on the stove could cause the soup to overflow?

Dont you notice that when you put soup on the stove it starts to bubble up as it gets hotter? the soup gets hotter and bubbles because it hits it boiling point. when something hits its boiling point it can bubble.the bubbles come from when the heat give of to the soup it creates expanded molecules. the "bubbles" are expanded and also because its turning into steam.any type of liquid can bubble. when the liquid reaches 212 degrees Fahrenheit it starts to bubble and also starts to rise.

Technology in science

I think that technology in science is very dificult but easy when you get the hang of it. Working with technology in science is going to have to be something that i do through out my whole life. There has been alot of problems because of the technology but thats what is going to happen sometimes and you have to be prepared for it. For me right now technology in science is going good and easy all it is is just typing instead of writing:)

Week1_Prompt#2

When a basketball bounces of the ground it uses two types of energy kinetic energy and potential energy. It turns to potential energy when the ball is about to hit the ground but its not there yet. The ball is still in the air when its in the potential stage. When the ball bounce's to the ground it switches there and turns to kinetic energy. When the ball is coming right back up its potential energy,the reason for that is because the ball is going to hit the ground again.
