See the full Portal 2 Walkthrough here: goo.gl ➜ Portal 2 Walkthrough/Lets Play▼ Portal 2: Chapter 1 - A Courtesy Call Portal 2 vs. Lewis as he takes on this mind bending game where he will have to work through brain aching test chambers only to see that the puzzles get harder and harder. As a general note, Lewis unfortunately knows what he is doing but he will add some good old English commentary on top of his amazing skill. Expect him to get stuck though! Enjoy. ►Portal 2▼ Portal 2 follows the player-character Chell after the end of Portal, in which she destroys the rogue artificial intelligence construct GLaDOS that ran the Aperture Science Enrichment Center where the game is set. In Portal's backstory, Aperture Science conducted experiments to determine whether human subjects could navigate dubiously safe "test chambers", until GLaDOS killed the scientists with a neurotoxin. The ending of the first game, retroactively patched just prior to the seq uel's official announcement, shows Chell being dragged away from the remains of GLaDOS by an unseen figure with a robotic voice, later identified by writer Erik Wolpaw as the "Party Escort Bot." A promotional comic shows that an estranged Aperture Science employee placed Chell into suspended animation for an indefinite amount of time, in an effort to save her life. Chell wakes to find herself in what appears to be a motel room. An announcer's voice guides her through a cognitive test before she is put back to sleep. When ...
Portal 2 - Walkthrough Part 1 [Chapter 1: A Courtesy Call] The Beginning - W/Commentary
Objective The aim of this experiment is to find out which method can be used for cooling a soda can beginning from room temperature.
Introduction This is one of those science fair experiments that will teach you about heat transfer by conduction, convection, radiation and evaporation. You must do some research to find out what these terms mean before you go ahead with your experiment.
Conduction: When heat is transferred from one molecule to the other without the molecules being subjected to mass movement. Convection: The transfer of heat when mass movement occurs. Radiation: When heat is given out in the form of waves, visible or invisible. Evaporation: When liquid molecules turn to vapor, carrying off heat.
There are several science fair experiments based on the above concepts.
If you want to cool a soda can, y our best bet would off course be the fridge, but you must know that objects in the refrigerator and the freezer get cooled mostly by convection (and partially by conduction). The air molecules inside your refrigerator are spread over a larger area as compared to liquid molecules. So what about objects placed in close contact with liquid? Liquid is much denser than air and would interact with molecules of objects in contact with them to a greater extent. There is a clue hidden in my last sentence, which will help you later.
Materials Cans of soda kept at room temperature (12 numbers), digital thermometer, ice cubes, two styrofoam cooling boxes, water, plastic wrap and a timer.
Procedure Fill a Styrofoam cooler box with ice only. Fill another Styrofoam cooler box with equal amount of ice, but this time mix water with it. Use a digital thermometer and measure the beginning temperatures of each of the following arrangements: Your freezer Your refrigerator The Styrofoam cooler filled with ice The Styrofoam cooler filled with ice-water The soda inside each can at room-temperature (seal the cans with plastic wrap immediately) Now three cans each containing soda must be placed in the following arrangements: Your freezer Your refrigerator The Styrofoam cooler filled with ice The Styrofoam cooler filled with ice-water Science fair experiments require that accurate written records should be kept of each finding. So note the beginning time of each arrangement.Check the temperature of the liquid (soda) in each can in each arrangement every 5 minutes and record the time and the temperatures. The experiment is over once the temperatures stops changing.Calculate the average temperatures of the three cans in each arrangement for every time point.Make a joint bar graph of the elapsed time on the x-axis and the average temperature the soda on the y-axis. Graphs made during science fair experiments speak volumes about your results, and about the effort you have put in. Just one look at the graph can reveal much more information than numbers can reveal.Now amaze yourself by finding out which cooling arrangement was the fastest! Knowing that the freezer is not the quickest way to cool a soda can be quite a revelation to most people.
