*To be confused with specific heat capacity

The Special Heat* of Pasta

Conclusion(s)

According to the data collection, mathematics, and conversions, pasta has a specific heat capacity of 44.4 kJ/kg*°C.

or

Avoiding this embarrassing "breakthrough"

Therefore, the investigation ultimately is a

fail

Ignoring this, we could theorize amazing uses for this mystical substance, pasta, which could be put to use absorbing large sums of heat, like protecting workers in metal-making factories or on re-entry vehicles coming back into the atmosphere.

Calculating the power supplied by the heat pad using control, instead of using the measurement of power supplied by the heat pad's labels.

Re-checking (again) math for errors.

The element with the highest specific heat capacity, hydrogen, averages in at 4.18 kJ/kg*°C.

Hypothesis: I will be able to find the specific heat capacity of pasta.

Introductory Material

Equation and other variables:

Data Collected

Q = mcT

Q = heat, or internal energy in Joules

m = mass in grams

c = specific heat capacity in Joules/kg * °C

T = temperature change in °C

QT = total energy

QW = energy applied to water

QP = energy applied to pasta

Watt: 1100 J/s

Mass of Pasta: 41.8g = .0418kg

Mass of Beaker/Water: 715.7g

Mass of Beaker: 217.9g

Initial Temperature: 18.5°C

Final Temperature: 95°C

Time: 4 min. 34 sec. = 274s

Energy Calculations

Solving for the energy applied to only the water:

Mass of Water: 715.7g – 217.9g = 497.8g = .4978kg

Specific Heat Capacity of Water: 4186J/kg

QW = .4978kg * 4186J/kg*°C * 76.5°C

QW = 1.59x105J

Solving for energy applied to the pasta:

QT = power * time

QT = 1100J/s * 274s

QT = 3.01x105J

QT = QW + QP

QP = QT – QW

QP = 3.01x105J – 1.59x105J

QP = 1.42x105J

Finishing Math

Solving for the Specific Heat Capacity of the Pasta:

Q = mcT

c= Q/mT

c= (1.42x〖10〗^5)/(.0418*76.5) = 44.4 kJ/kg*°C

44.4 kJ/kg*°C

Stirring the Pot

Also can be referred to as data collection

The Plan

Materials

• Pasta (Spaghetti)

• Pot

• Heat pad

• Beaker

• Water source

• Thermometer

• Stop watch

• Mass scale (grams)

Procedure

• Locate and record the Wattage of the heat pad

• Plug in heat pad, and turn it to high

• Fill beaker with water

• Measure and record the combined mass of the beaker and water

• Isolate 40 strands of spaghetti, then measure and record the total mass of this spaghetti

• Pour water into pot

• Break spaghetti into half (this will allow it to fit completely into the pot) and drop it into the pot as well

• Place thermometer into pot, measuring and recording the initial temperature of the water/pasta

• When the heat pad appears to be at its maximum temperature, place pot with items added onto the heat pad, starting the stop watch

• Measure and record the mass of the empty beaker

• When the thermometer’s temperature reading no longer appears to be increasing, stop the stop watch, and record temperature reading

• Pull pot off from pad (placing on a surface that will not be damaged by excessive heat)

• Turn down, then turn off/unplug heat pad

• Record the time displayed on the stop watch

• Clean up work area
