Useful conversion formulas: OC to OF Multiply by 9, then divide by 5, then add 32 °F to °C Deduct 32, then multiply by 5,then divide by 9 Answer the following: 1. Water freezes at 0C. 2. Water boils at OF 3. Normal human body temperature is OF, which is equivalent to 4. Taking temperature accurately Record the following temperatures in your room environment. In each case, allow the bulb end of the Celsius thermometer to remain in or on the sample for a minimum of one minute before taking a reading. Extra credit points will be given ifyou also convert to F, but this is optional. a) Room temperature (air Actual thermometer reading oC conversion b) Surface of your skin Actual thermometer reading eC conversion c) Cool tap water. Place your beaker in the sink at your lab table and let the cold tap water run into the beaker for at least a full minute. Important: allow the thermometer to stabilize in the water for a minute before taking a reading Actual thermometer reading OC conversion: d) Hot tap water. Place your beaker in the sink at your lab table and let the hot tap water run into the beaker for at least a full minute. Important: allow the thermometer to stabilize in the water for a minute before taking a reading Actual thermometer reading OC conversion: e) Interior of refrigerator. Place thermometer inside (and close the door) for at least a full minute. Actual thermometer reading OC conversion:

Explanation / Answer

Question: 1. Water freezes at _o F = _o C

Answer: 32o F = 0o C

Water freezses at 32 degrees Fahrenheit (32o F).

Using the conversion formula o F to o C: Deduct 32, then multiply by 5, then devide by 9.

Therefore, 32o F = (32-32) x 5 / 9 = 0o C

Hence the answer is Water freezes at 32o F = 0o C.

Question: 2. Water boils at _o F = _o C

Answer: 212o F = 100o C

Water boils at 212 degrees Fahrenheit (212o F).

Using the conversion formula o F to o C: Deduct 32, then multiply by 5, then devide by 9.

Therefore, 212o F = (212-32) x 5 / 9 = 180 x 5 / 9 = 100o C

Hence the answer is water boils at 212o F = 100o C.

Question: 3. Normal human body temperature is _o F, which is equivalent to _o C.

Answer: 98.6o F = 376o C

The average normal body temperature is 98.6 degrees Fahrenheit (98.6°F).

Using the conversion formula o F to o C: Deduct 32, then multiply by 5, then devide by 9.

Therefore, 98.6o F = (98.6-32) x 5 / 9 = 66.6 x 5 / 9 = 37o C

Hence the answer is normal human body temperature is 98.6o F, which is equivalent to 37o C.
