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

3 potato cubes using the dimensions from above. 2. Obtain TEACHER’S SIGN-OFF BEFORE you proceed! 3. Submerge the potato cubes (cells) into the iodine solution for 20 minutes. 4. While you are waiting for 10 minutes‚ calculate the surface area‚ volume‚ and surface area to volume ratio for each of the 3 potato cubes (cells). AFTER 10 Minutes 5. Carefully remove the potato cubes (cells) from the iodine solution and place them on absorbent paper towels. 6. Cut each cell in half and observe the

Achievement Standard 91106 (2.9) Log number: 4 Title: The Heat Text type: Film Director: Paul Feig The film ‘The Heat’ is a film about a very formal but cocky FBI agent who is paired with a really aggressive Boston cop to take down a ruthless drug lord. The FBI agent‚ Sarah Ashburn‚ only agreed to take on this case to get a promotion. The Boston cop‚ Mullins‚ was chosen to do this case because she knew the town better than anyone else did. Sarah Ashburn and Mullins did not like each other

Friction on a surface. Aim: To establish the relation between weight of a rectangular wooden block lying on a horizontal table and the minimum force required to just move it using a spring balance Materials required: A rectangular block of wood with a hook ‚ set of weights‚ strong thread and a spring balance. Theory: The force of friction acting on a block of wood is proportional to the normal reaction acting on the block. By the third law of motion‚ normal reaction is equal to the weight

Mechanisms of Heat Transfer Prepared by: Ms. Ana Antoniette C. Illahi 1 Conduction • conduction (or heat conduction) is the transfer of thermal energy between regions of matter due to a temperature gradient. Heat spontaneously flows from a region of higher temperature to a region of lower temperature‚ and reduces temperature differences over time‚ approaching thermal equilibrium.

Term Report Microsoft Surface Table Acknowledgements We would like to express our deepest appreciation for our professor‚ Dr. Michael Kamins. It would have been practically impossible for us to pursue this project without his invaluable advice and guidance. We would also like to thank our classmates for encouraging us during our presentation and providing great advice to improve our project. We would also like to thank the Stony Brook College of Business for allowing us to use the

but to adopt or not use the product. Society currently is in a state of conformity and how the saying “go with the flow” goes. Most innovations of today are widely accepted by a large group of people and that in turn leads to more and more adopters‚ proving the success of that innovation. Eventually those “innovative” ideas will run out because everything humanely possible will be in existence. Microsoft’s Surface Pro laptop-in-disguise1 tablet is no different‚ a “flawed”2 device which has seen improvements

Surface Tension My problem was to find out how to test or measure surface tension. I think the reason of some of the force in surface tension is cohesion and gravity. Surface Tension is the condition existing at the free surface of a liquid‚ resembling the properties of an elastic skin under tension. The tension is the result of intermolecular forces exerting an unbalanced inward pull on the individual surface molecules; this is reflected in the considerable curvature at those edges where the
