Hypothesis 1. AC – The electrical energy will be converted to heat energy with the use of a converter. This heat energy will transfer to the guitar string (nichrome‚ a good conductor) so when the Styrofoam (polystyrene with a melting point of 240) touches the string‚ it will melt and will eventually cut the Styrofoam to its desired shape. DC - The chemical energy in the dry cell will be converted to heat energy with the use of a converter. This heat energy will transfer to the guitar string (conductor)

QUESTION 2.1: Do you expect heat to flow into or out of the cup into the surrounding atmosphere? ANSWER: The heat flow is expected to flow out of the cup into the surrounding because temperature of the cup is more than its surroundings. QUESTION 2.2: Is the difference between the final and initial temperatures‚ T_f − 푇푖‚ positive or negative? Explain why you gave the answer you did. ANSWER: The difference between the final and initial temperatures is negative. This is due to the fact that gas

of a fluid that needs a heat source and a cold source to work. The rest of the notes will deal with supporting this idea and giving some examples of convections currents here on earth. Once the earth collects enough material it will start to get so heavy that it compresses inward toward the center of gravity a lot. This smashing of the atoms of rock causes them to get really hot. Radioactive atoms are also giving of energy. The combination of the two heat sources made the earth

analyzed. An expression for the efficiency of the simple cycle is introduced. Theoretical analysis shows that strong and weak solution concentration limits play a decisive role in the value of cycle efficiency. S ystem efficiency with consideration of heat and work added to the system is well defined. The limits of regeneration temperature and mass of strong solution per kg of produced vapor are found highly dependent on the operating concentration of desiccant. Experimental results show that solution

The traditional dryer always heats air surrounding‚ and transports the hot air to roller around. The humid air resulted in this procedure will be excluded out‚ leaving dry air to keep drying . The traditional design does not recover the heat‚ and is therefore very inefficient. However‚ the traditional design is simple‚ reliable‚ reasonable-priced .

Building and the Environemnt Introduction A berm house is a house that is banked with earth. The design and building methods that are used aid the building to require less energy being put into the building when construction is complete and the building is being used as its intended. Construction The Caer Llan berm house was “designed to be “massive” rather than “lightweight”. The use of vast quantities of block‚ concrete‚ etc‚ is intended to act as a stabiliser‚ both structurally

ABSTRACT This laboratory focused on the thermodynamic processes involved when two incompressible substances are mixed together. 12 experiments were performed‚ 10 involving the combination of a measured amount of hot and cold water and 2 involving the combination of ice and liquid water‚ the majority of these experiments were performed three times. The average variance in final temperature for each experiment was less than 10 percent providing proof of repeatability. Equipment used during the

6 STROKE ENGINE INTRODUCTION: Both two stroke and four stroke engine consumes more amount of fuel in which half of the energy goes waste as heat energy. Using SIX STROKE engine the heat energy is minimized to a greater extent by converting the heat energy into useful power stroke.

D6T thermal sensor and People Counting Algorithm In this thesis work‚ a new indoor people counting algorithm is created by using Omron D-6T thermal sensor and Raspberry Pi. The sensor periodically generate thermal map of heat emitted in its field of view which is a one dimension array and pass the array to Raspberry for further processing. The people counting algorithm is created in Raspberry Pi by processing thermal map generated by D6T. After processing the number of people indoor is obtained
