Conduction and heat transfer

Burning wood often pops and crackles • The reason why a burning wood pops and crackles is because of two things. First is due to the property of conduction. Wood is not a very good conductor of heat. Second reason is due to thermal expansion. An increase in temperature in any matter results to a change in the volumetric property of matter. Wood expands when heated or in this case burned. The burning part of the wood is expanding but since wood is not a good conductor of heat, the other parts of the wood that is not burning only experiences a very little amount of increase in temperature. Thus, the expansion of the unburned parts of the wood is…

Heat Transfer by Conduction Lab

Vocabulary: Conduction- the passage of energy, particularly heat or electricity, through something Rate of Change- the ratio of the difference in values of a variable during a time period to the length of that time period Calorimeter- an apparatus for measuring the amount of heat given out or taken in during a process such as combustion or change of state. The measurements are often made by observing the amount of solid liquefied, or liquid vaporized, under set conditions. Conservation of Energy- the principle that the amount of energy in an isolated system remains the same, even though the form of energy may change Data: See Data Sheet Discussion Questions: At the start, the cold cup had the most potential energy….

A Book Report on “Heat” By Mike Lupika

Sportswriter named Mike Lupika intelligently wrote a piece of story that proves life is still beautiful despite the heartbreaks and difficulties. The author also portrays a story that illuminates the truth that a person’s talent is special and must be developed by the one who was gifted as such. The social behavior displayed in the book is very degrading that some of the male characters in the book including their adult friends lied to the authorities (“Heat”). However, the interesting and notable parts of the fiction are those that mentioned fast food like Mc Donald and those drink and clothing brands that were mentioned in the book. According to Common Sense Media Website, the book entitled “Heat” has 220 pages…

Solution Calorimetry: Thermodynamics of Potassium Nitrate

A determination of thermodynamic variables of KNO3 is presented. KNO3 was heated and dissolved in varying volumes of distilled water. Upon dissolution, the KNO3 solution was removed from heat and the temperature was recorded once crystals formed. For each solution, ∆G the Ksp were found with the temperature and molarity values. ∆H and ∆S were found through the linearization of the data with a plot of lm(Ksp) vs. ∆G becomes increasingly negative as temperature and concentration increased. ∆H was found to be 29.46 kJmol-1 with a 15.7% error compared to literature values. ∆S was found to be .120kJmol-1K-1 with a 3.81% error compared to the literature value. III. Introduction Potassium Nitrate is a molecule of many applications. Potassium Nitrate is…

Stone Therapy Treatments -Understand How to use Stone Therapy Treatments

References – IHM (Indian Head Massage), BM (Body Massage), AM (Pre Blended Aromatherapy Oil Massage, HSM (Hot Stone Massage) Knowledge – B24 – Outcome 10 – HSM UNDERSTAND HOW TO USE STONE THERAPY EQUIPMENT a. Explain the types of safe, purpose-built stone heating equipment and how to use and position them safely. Hot stone heaters do vary with each manufacturer and all heaters operate in different ways. Some may take longer to heat up in relation to the water capacity (the larger the heater capacity in litres, the longer it take to heat) depending upon the size bought, that varies depending upon the number of stones to be heated. It is important to use stone heating equipment that has been…

Refrigeration and Air Conditioning

1. DEFINATION OF REFRIGERATION Refrigeration is defined as “ the branch of science that deal with the process of reducing and maintaining the temperature of confined space or material below the temperature of surrounding” the system maintain at lower temperature is known as refrigerated system and equipment used to obtain this is known as refrigerator. The cooling effect produced by this equipment is the refrigerating effect. 2. PRINCIPLE OF REFRIGERATION According to Clausius’s statement of second law of thermodynamics ,heat does not flow from low temperature region to high temperature region without help of external energy. Thus ,in order to transfer heat from low temperature to high temperature ,work must be supplied to refrigerator, which produces cooling effect.such cooling may…

Peter Stark

Summary of Stark’s article Peter Stark’s article As Freezing Persons Recollect The Snow—First Chill—Then Stupor—Then The Letting go: the cold hard facts of freezing to death talks and explains what happens to the human body when a person is freezing to death but it also gives an enjoyable story for the reader. The character in this story is in his way to a friend’s house for dinner and night cross country ski when his jeep slides off the road and gets stuck in a snow bank. Stark made it clear that his character was not panicked at first but just simply worried about missing the dinner with his friends. Not wanting to miss his plans the character puts his skis…

Heat Transfer

Practice Problems Set – 1 MEC301: Heat Transfer Q.1 The slab shown in the figure is embedded on five sides in insulation materials. The sixth side is exposed to an ambient temperature through a heat transfer coefficient. Heat is generated in the slab at the rate of 1.0 kW/m3. The thermal conductivity of the slab is 0.2 W/m-K. (a) Solve for the temperature distribution in the slab, noting any assumptions you must make. Be careful to clearly identify the boundary conditions. (b) Evaluate T at the front and back faces of the slab. (c) Show that your solution gives the expected heat fluxes at the back and front faces. Q.2 Compute overall heat transfer coefficient U for the slab shown…
