Heat Trasfer as Engergy Exchanges (Update)

When dealing with temperature in physics we need to make sure that we are using the correct scale. Here we can see how to change Celsius into Fahrenheit. Fahrenheit is not a unit that is used often in calculations. However, changing Celsius to Kelvin is fairly easy, but it is not needed when you are looking for the change in temperature.

Here we looked into the buoyant force of the gas inside a bubble. We needed to predict how the flame would expand if we apply an open flame to it. We predicted that it would explode but it in fact expand horizontally and upward do to momentum and expansion. 

This is the calculation of finding the ending temperature of water when it does not do a phase change. It is a simple example and will most likely not be on the quiz/ test in this form.

These are our prediction and actual result in adding two different water temps. together. The top one is when the two water mixes-up with each other while the second one is when they are separated by a can. When they are separated it takes a longer time

This is our physical representation of what is happening between the hot water the can and the cold water molecules. The hot water is moving fast and transferring its energy into the can. Then the can transfers the energy into the cold water. The arrows represents the magnitude of the energy

 This is the graph where the equation Q=mc delta T is derived from.

 

This is an updated chart of the lab that was done in the first day of class. It shows the temperatures of the transfermation.
