3/24 Electric Field

Here we needed to find the total Energy on the y axis

Calculations for total Energy





Definition of Electric Force. It is very similar to gravitational force.

3/17 Entropy and Diesel cycle

Here are some equations that we learned for entropy and enthalpy



The rest of these pictures are all calculations for the Refrigerator Freezing Ice problem.






3/12 More Engine Cycles

Here we calculated the constants used for constant pressure and constant volume.











3/10 Engine cycles

Named different variables than can have an effect on a thermodynamics problem
             
3 different types of processes that happen: isobaric, isochoric, and isothermal.





Explained how using a heat gun can create heat to convert into work

Equation for internal energy

Calculations of how we calculated Work, Heat, and Internal Energy at different point in an engine cycle.

3/19 Electric Charge and Force

Charged a balloon with different objects and then see if the balloon sticks to a uncharged object.

We used strips of Scotch tape to see how the strips with the same charge and with opposite charges reacted.

Here we derived an equation for the Force of a ball hanging from  a string with an angle theta.


This is our graph that we fit manually.


Calculations of electrical force of opposite charged particles.


Here we calculated the ratio between electrical force and gravitational force. Clearly this ratio how much stronger electrical charge is with equal distances. However, may not be true under extreme circumstances.

3/5/15 Molecular Kinetic Energy


In this experiment, we increased the temperature in a tube by increasing the pressure. Enough heat to burn a small piece of cotton inside. These are the calculations where we found the final temperature.

3/3 Pressure and Temperature

Here we predicted what was going to happen when a heated aluminum can with a little bit of water was placed upside down in a container of cold water.

This is a graph of volume vs. pressure. Not linear as we predicted.

Determined the units of Area.


Our predicted graph of temperature vs. pressure.
