Chapter 15 & 16: Temperature‚ Heat & Heat Transfer Temperature is a measure of the average (not total) translational kinetic energy. ●ex: there is 2x as much total molecular kinetic energy in a 2L of boiling water than one‚ but the temp of the two volumes are the same (average of translational kinetic energy per molecule is the same in each → Internal Energy- the total of all molecular energies: kinetic+potential (SAME TEMP) ● Ex: apply a flame to 1L h2o for a certain time and its temp rises

Purpose Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries‚ even when the surrounding temperature varies and is of higher or lower temperature than what is normal. The purpose of thermoregulation is to balance thermal inputs and thermal losses in the body so as to maintain a relatively constant core temperature of approximately 36.7 degrees celsius. If this was unable to take place the body may not be able to functions properly and it could result

thing in automotive fuel may very well be hydrogen. Automakers rapidly are closing in on making hydrogen fuel cell vehicles an everyday fact of life‚ with several test models set to debut over the next few years. Hydrogen fuel cells to power vehicles are desirable‚ experts say‚ because hydrogen is a renewable fuel that can be used to create electricity to run cars. A chemical reaction between oxygen and hydrogen produces the electric power‚ and when pure hydrogen is used‚ the only emission from the tailpipe

Effect of different temperatures on the rate of an enzyme controlled reaction I will place starch and amylase into five water baths which are at different temperatures‚ and record the time it takes to break down the starch in the solution. Independent variables The independent variable is what I am going to change in my experiment. In this case it is the temperature of the water in the five water baths- 10‚ 25‚ 40‚ 55‚ 70 degrees Celsius Dependant variable This is what will stay the

Good morning/afternoon Mrs Morgan and fellow class members. Good poetry makes you think and feel about issues and ideas raised by the poet. Judith Beveridge explores the beauty of nature and man’s relationship to it. Judith Beveridge shows the cruelty of humans towards animals and nature in her poems. The first poem I have chosen to talk about is “The Shark”. This poem is about a bunch of fishermen on a boat‚ who catch a shark and later discover that the shark has eaten a young boy. “The

butterflies need to regulate their body temperatures through thermoregulation. There are two types of ways to regulate body temperature. The first one is ectothermy. Ectothermic animals‚ or cold-blooded animals‚ rely on outside sources to heat or cool themselves. Cold-blooded animals can lie under the hot sun to heat themselves up and prepare for flight or to move around. However‚ if there is no source of heat‚ they are not able to raise their body temperature to the correct level for movement. Butterflies

Chemistry Write-Up The Thermal Decomposition of Sodium Hydrogen Carbonate Aim: When Sodium Hydrogen Carbonate (NaHCO3) is heated‚ Carbon dioxide and water are given off to leave a white powder. The aim is to find the equations for this reaction. Hypothesis: The experiment will prove which of the equations below is true. It will tell us whether Sodium Carbonate is produced or Sodium Oxide. 2NaHCO3 Na2CO3 + CO2 + H2O 2NaHCO3 Na2O + 2CO2 + H2O Variables: Independent: Original

What is a Work Breakdown Structure (WBS)? http://www.adeak.com/2010/01/what-is-a-work-breakdown-structure-wbs/ Once we have identified all of the things that we are supposed to produce in the project‚ it is necessary to develop the specific items of work that must be done to complete all of the work. The work breakdown structure takes the project and divides it into smaller pieces. These can be called subprojects. The subprojects can be broken down into smaller pieces. This process of breaking

La película de Pedro Almodóvar Mujeres al borde de un ataque de nervios nos enseña un perspectiva inversa sobre el carácter del hombre y la mujer. Esta película carece del los hombres masculinos tradicionales y nos ilustra que las mujeres ya no son el sexo débil. A pesar del título‚ las mujeres en esta película son retratadas como personajes fuertes e independientes y los hombres son retratados como los personajes débiles que son responsables por las desgracias de las mujeres. La razón principal
