The document summarizes an experiment conducted by a group of 5 students to determine the food energy provided by peanuts, cashew nuts, and almonds. The group recorded the initial and final mass and temperatures of each food sample as it burned. Their results showed that peanuts provided the highest amount of energy through the greatest change in mass, while almonds provided the lowest. Temperature data of the burning foods was also recorded over time.

Petroleum engineers carry out a myriad of tasks including testing, designing and implementing methods for the extraction of petroleum products from the surface of the earth as well as the ocean floor. To begin with, petroleum engineers need to locate a suitable dig site. This is followed by the
setting up of the required machinery. Engineers must overlook the extraction process which includes the removal as well as processing of petroleum. Petroleum engineers must have the expertise and ability to work closely with geologists and other professionals to extract and refine petroleum products in a safe and efficient manner.

Performance investigation of conventional heat pipe with hydrocarbon as worki...eSAT Journals
Abstract
This work attempts to analyses the performance of conventional heat pipe with hydrocarbon as working fluid. The performance
investigation involves the determination of thermal resistance of conventional heat pipe at various heat input. And to determine
the best hydrocarbon working fluid out of the acetone and methanol. Conventional heat pipe is filled with acetone and methanol
with the filling ratio of 60 % with this filling ratio the performance of the device is investigated.
Keywords: Working Fluid, Heat Transfer, Thermal Resistance.
Experimentation to predict the thermal performance of closed loop pulsating h...eSAT Journals
Abstract
The closed-loop pulsating heat pipe is a type of small heat transfer device with a very high thermal conductivity. It was invented to meet the requirement for smaller heat transfer devices. It can transfer sufficient heat for heat dissipation applications in modern electronic devices. The objective of this work is to study thermal performance of closed loop pulsating heat pipe with acetone and methanol as working fluid.. Copper has been selected as material for heat pipe due to compatibility of copper with acetone and methanol as working fluid. Filling ratio of the working fluid significantly influence on the performance closed loop pulsating heat pipe. From the past studies it was observed that filling ratio of 30-75 % provides the best result hence 60 % filling ratio has been selected for this filing ratio the thermal performance of closed loop pulsating heat pipe with acetone and methanol as working fluid is investigate.
Keywords: closed loop pulsating heat pipe, condenser, evaporator, working fluid, filling ratio.

3. SCIENTIFIC CONCEPT
• Food energy is the amount of energy
obtained from food that is available
through cellular respiration.
• As food burns, it releases energy.
• Formula to calculate food energy:
4. ENGAGE
• The nuts provide us energy. Why?
• Which nut has the highest energy? And
which has the lowest energy?
Cashew
Nut
PeanutAlmond
5. ENPOWER
• Material & Apparatus:
– clamp
– stand
– boiling tube
– food: peanut, cashew nut, almond
– a mounted needle
– data logger and computer
– temperature sensor
– Bunsen burner
– matches
– electronic scales
7. ENPOWER
• Procedures:
1. Connect the temperature sensor to the first socket
on the data logger.
2. Weigh the food sample and record it. Add 30 cm3
water to the boiling tube.
3. Start the sensing software and see that it recognizes
the sensors we attach.
4. Set up the software to record. Heat the food in a
Bunsen flame to light it.
5. Heat the tube of water with the burning food until it
has completely burnt. Re-light the food if necessary.
6. Weight the burnt food with the same electronic
scale.
20. RESULTS
• Energy released from cashew nut per gram(J)
=
= 4957.3 J
= 4.957 KJ
• Energy released from peanut per gram(J)
=
= 6507.2 J
= 6.507 KJ
21. Discussions
•What do you observe from the
graph about the water
temperature?
•Do all the nuts have same level of
energy?
•Does the increase of temperature
among the three types of nuts is
the same?
22. •From the graph, which type of nut
produces the highest energy?
•Arrange the food sample according
to its energy in ascending order.
•Is your result accurate? Does all
the energy from the nuts is used to
heat the water or some heat is lost?
How could this affect your results?
23. ENHANCE
•Do you eat to live OR live to eat???
•WHY???
OR
eat to live live to eat
24. • Many will say they eat to live because it is
necessary to sustain life and as a respond to
hunger. They eat in order to obtain the strength
to carry on life's daily activities.
• However, there are also people who live to eat.
They love to eat and they crave food of any and
every kind. Live to eat is a habit of enjoying
eating. This kind of people can easily suffer
from obesity.
• My advise is we should eat to live, don’t live to
eat.
25. Unique Features of This Activity
• the temperature can be recorded every second
• the temperature can be recorded in three decimal
places
• the setup of the apparatus is quite simple and we only
need a test tube and a temperature sensor to test the
energy of the nuts
• the experiment gives only a very approximate estimate
for each foodstuff, so the students can use any type of
food to replace the nuts and calculate the food energy.
• students can compare the graphs and differentiate the
energy between the three types of nuts
