Day 1: Heat Flow and Specific Heat

Introduction.
Professor Mason talked about himself and his past projects to get to know our teacher.

First lesson review of temperature:

Reviewed conversion from Fahrenheit to Celsius. Used y = mx + B. Picture is a graph of the work we done in class.

Later on Prof. Mason asked us to think about a bubble filled with methane gas and what would happen if it was light with fire. Video below of the demonstration.
Next we did some a problem: Given two cups filled with 50g of water at 25 deg C and 65 deg C what would the final temperature when mixed? Picture of work below.

Next same question different masses. Picture of work below.
Afterwards Prof. Mason asks, "What if there is a aluminum can in between the hot and cold water, would the graph of heat transfer be the same?"

Our prediction below.

Picture of experiment below.

Picture of logger pro data and graph below. The graph turns out to be similar to the previous experiment just elongated.

Picture of our team work, Ivan, Ashuai, and Andrew.

Prof. Mason asked us to write 5 things that would effect temperature of a liquid. Picture of work below.

Next we worked on heat transfer and heat flow question. Picture of work below.

In order to get a better understanding of heat flow and heat transfer we did a small experimenter. Picture of the experiment below.
Picture of rating of water heater for the experimenter.
Graph of heat vs. temperature
Linear fit of same graph.
Some work of comparing numbers with logger pro.
Graph of heat per unit mass versus temperature.
Linear fit of same graph.
Picture of work correlating the heat experiment.
Summary of things learn and done in day one.
Got to know Prof. Mason and the work he has done in the past and what type of person he is (Funny).
Reviewed stuff about temperature and the really world significance of y = mx +b.
Showed that our previous understand of heat transfer could be wrong thanks to the fire bubble experiment.
Showed that medium matters when transferring heat and what that parameters control heat transfer.
Lab to solidify the concepts Prof. Mason discussed about heat transfer by using logger pro.
