*To be confused with specific heat capacity
According to the data collection, mathematics, and conversions, pasta has a specific heat capacity of 44.4 kJ/kg*°C.
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.
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
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
QT = power * time
QT = 1100J/s * 274s
QT = 3.01x105J
QT = QW + QP
QP = QT – QW
QP = 3.01x105J – 1.59x105J
QP = 1.42x105J
Q = mcT
c= Q/mT
c= (1.42x〖10〗^5)/(.0418*76.5) = 44.4 kJ/kg*°C
44.4 kJ/kg*°C
Also can be referred to as data collection
• Pasta (Spaghetti)
• Pot
• Heat pad
• Beaker
• Water source
• Thermometer
• Stop watch
• Mass scale (grams)
• 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
