 * 1) Convert 50oF to Celsius. Show Your Work


 * 1) Convert your answer to #4 above to Kelvin. Show Your Work.


 * 1) If a room is kept at 72oF at all times, what is the temperature of a table that has been in the room for days?   Explain your answer.


 * 1) Is a glass of ice water is placed on the table in the room, explain what will happen to the temperature of both the water and the table during the next hour.


 * 1) If you came back to this hypothetical room two days later what would be the temperature of the water in the glass?   Explain your reasoning.


 * 1) Which of the four laws of Thermodynamics best explains what is going on in the room above?   Explain your answer.

Over
 * 1) A student places a cup of ice water into a tub of warm water and collects the following data.


 * Time ||  1 min  ||  2 min  ||  3 min  ||  4 min  ||  5 min  ||  6 min  ||  7 min  ||  8 min  ||  9 min  ||
 * Temp ||  4oC  ||  6oC  ||  8oC  ||  10oC  ||  12oC  ||  14oC  ||  16oC  ||  18oC  ||  18oC  ||

Graph the data


 * 1) What is the rate of change for the water in the cup? Show your work.


 * 1) Look carefully at the data. What is the temperature of the room in which the cup and tub are sitting.   Support your answer with data.


 * 1) Use the 3rd Law of Thermodynamics to explain why the ice water warmed up.
