Transcript of Lab 1 B Objectives 1.Calibrate a thermometer 2.Dimension analysis 3.Generate a graph on excel.
A typical thermometer is a calibrated, or numbered, glass tube containing mercury.
The silver mercury in the tube rises, or expands, when warmth of an object increases.
.
Fahrenheit.
The first scale is measured in degrees Fahrenheit.
The range from freezing point to boiling point on this scale is 32 to 212 degrees.
Celsius
The other scale is measured in degrees Celsius.
. The range from freezing point to boiling point on this scale is 0 to 100 degrees.
Temperature Conversion Table
From
Fahrenheit (F o to C o) (F - 32) * 5/9
Celsius (C o to F o) (C * 9/5) + 32
Kelvin (C o to Ko) C + 273
Math Start with what is given. If the problem is in the form of a math
equation (ex. 36 eggs = ______________ dozen, it’s the number written first.
Don’t bother with the numbers, look at the units !!
Whatever the units your first number has, put that down below diagonally in the next blank.
36 eggs
eggs
Conversions
Decide what you have to convert the unit you just wrote into.
Put the conversion unit above
A conversion is a unit that has an equivalent value to another unit
Ask yourself how many of the other units are in the larger unit. Fill in the other number
36 eggs
eggs
Dozen1
12
Do the math. Multiply across the top write the number
down. Multiply across the bottom write the number
down, Divide the two numbers. That is your answer.
36x 1 = 36 1 x12 = 12 36 / 12= 3 dozen
Example 2 2000 seconds is how many days
2000 sec
60 sec
1 min
2000 Hours / 3600 =0.55 hours
60 min
1 Hour
