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

only to Van der Waals forces that operate by induced polarity in non-polar molecules. Cohesion‚ along with adhesion (attraction between unlike molecules)‚ helps explain phenomena such as meniscus‚ surface tension and capillary action. Mercury in a glass flask is a good example of the effects of the ratio between cohesive and adhesive forces. Because of its high cohesion and low adhesion to the glass‚ mercury does not spread out to cover the bottom of the flask ‚ and if enough is placed in the flask

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.

in this report is heat transfer in a concentric tube heat exchanger. A heat exchanger is a device used to transfer heat from a hot fluid to a colder fluid. Heat exchangers are widely used in the petroleum industry for various reasons. Some of the most important reasons are theta heat exchangers increase the process efficiency‚ conserve energy‚ reduce maintenance and provide employee safety among many other reasons. The main objectives of the lab study were to determine the heat transfer rate‚ the

Microsoft’s Surface Pro laptop-in-disguise1 tablet is no different‚ a “flawed”2 device which has seen improvements to its design and structure over the past few years making it slowly approach perfection. Microsoft’s Surface Pro is one of the newer innovative devices that was initially introduced in February 20133 and has seen a much shorter succession cycle than that of any other popular tablet manufacturer‚ namely Apple. Adoption rate was not at its best with the initial introduction of the Surface Pro

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

Introduction to Measurement Mass‚ Length‚ and Volume Introduction Much of what we know about the physical world has been obtained from measurements made in the laboratory. Skill is required to design experiments so that careful measurements can be made. Skill is also needed to use lab equipment correctly so that errors can be minimized. At the same time‚ it is important to understand the limitations of scientific measurements. Concepts Measurement Significant figures Accuracy
