• Celsius• Fahrenheit• Kelvin

• Who created the temperature scale?

• When was it created?• How or why did they create it?• What is the temp of: (put them in

order)– Liquid nitrogen– Body temp– Boiling water– Freezing water– Room temp– Absolute zero

• What is the conversion to the other two scales?

Food Lab Calorie:- Doritos = 5.4 C/g - Sun Chips = 5.0 C/g - Tostitos = 5.0 C/g

Lab ReportPurpose NOT a problemNo hypothesis or ConclusionInclude ALL charts and calculations in the Data section.

Analysis should include: - Definition of calorie and how it can be measured. - Description of HOW a calorimeter works - Use scientific language: Thermal Energy, Temperature, Heat

(Flow of thermal energy) - Results from data table and charts: USE DATA NUMBERS AS

EXAMPLES - How a homemade calorimeter differs from a “Bomb

Calorimeter”Where did the error in our experiment come from?

ABSOLUTE ZERO

• Gases shrink by 1/273 of their volume at 0C for each degree lowering in temperature

• At -273 Celsius it would contract by 273/273 volumes and be reduced to zero volume

• Same result happens with pressure

• Pressure goes down 1/273 for every degree lowering of temperature

• At -273 Celsius the pressure would be zero.

ABSOLUTE ZERO

-273 C

No more energy can be taken from a substance at absolute zero

• Add Percent Error Calculation for each chip in data

(True Value – Experimental Value) X 100

True Value

True Values:

- Doritos = 5.4 C/g

- Sun Chips = 5.0 C/g

- Tostitos = 5.0 C/g

Research “Bomb Calorimeters” to see where the error came from.

Purpose: Turn liquid ½ & ½ into solid ice cream, using heat transfer

Data: observations

Analysis: Include the following:

- What state changes happened?

- Which direction did the thermal energy flow?

- Why did energy flow the direction it did?

- What law (or laws) of thermodynamics apply?

- How was that law (or laws) demonstrated?

Use observations that were made as proof for these answers.
