Heat it up, cool it down.

So on thursday our goal was just to determine the temperature exchange between a unknown hot metal and water in a calorimeter (we had two foam cups + a foam top as our calorimeter, haha).

Heating up some metal

Unknown salt, we used these to determine if the reaction of adding them to water was exothermic or endothermic.

Our components for our self-made 'calorimeter' :)

Empty classroom! I'm always one of the last to leave. Not always because we are slower, but because I stay and sometimes do the pre-assignment for the next lab, and chat with my teacher.
