Big Temperature

Put some hot water, warm water, and cold water in three bowls. Just use water from your faucet, and please be sure that the hot water is not too hot to touch! Place a finger in the hot water and a finger of the other hand in the cold water. After a few seconds, place them both in the warm water. Describe the sensations. Can you trust your senses for measuring temperature? Explain your answer. Placing finger A(pointing finger on left hand) in the “hot” water, my finger felt a hot and heated sensation, and placing finger B(pointing finger on right hand) in the “cold” water my finger felt a cool/numb feeling. After transferring finger B from the cold water into the hot water the feeling was stranger, the exterior of my finger felt hot almost immediately but the interior still felt cool. I believe you can trust your senses sometimes not most of the time, for example if you touch a hot pan you do not feel right away due to your nerves taking time to let your brain receptors know “Ouch! That is hot!”

2. You know that the normal temperature for a healthy person is about 98.6 Fahrenheit degrees. Express this temperature in degrees Celsius.
F = 1.8C + 32 F = 1.8C + 32
F – 32 = 1.8C
(F-32)/1.8 = C
C = (98.6 – 32)/1.8
= 66.6/1.8
= 37degC

(degrees Celsius/Fahrenheit)
750 degrees Fahrenheit

4. Answer the following questions:
A. Describe and explain the meaning of the graph.
The graph shows how after the time the water begins to slowly decrease in temperature until it is at a stable temperature. B. What is happening to the average kinetic energy of the molecules during the five minutes in which the temperature of the water was being recorded? Explain your answer. Well, after each 30 second interval the temperatures begin to become equal, after the five minutes are up both the waters just about the same exact temperature.

5. A metal rod is 25.000cm long at 25.0 degrees Celsius. When heated to 102.0 degrees Celsius, it is 25.054 cm long. What is the coefficient of linear expansion for this metal? ΔL=aL₀ΔT

a = ΔL/(L₀ΔT)
a = (25.054 cm – 25.000cm)/[25.000cm(102.0ºC – 25.0ºC)]
a = 2.805×10-^5/ºC

6. Water investigation
A. Place a small drop of water on wax paper. Describe how the water behaves, what characteristic of water are you investigating? When I place a drop of water on a piece of wax paper, the drop stays together and is able to be moved with the direction in which I move the paper, the water does not wet the paper. This would be investigating adhesive force B. Take a glass of water and see if you can float a paper clip or pin on it. What characteristic of water are you investigating? Surface tension.
