Name: States of Matter Lab Procedure: Go to: http://phet.colorado.edu/en/simulation/states-of-matter and click on Run At present States of Matter Review: i) Kinetic energy (KE) is the energy of ______motion______. two) Potential free energy (PE) is the energy of _____position_______. iii) What holding of a substance corresponds to the average KE of its particles? temperature 4) What property of a substance corresponds to the boilerplate PE of its particles? phase v) List the three common states of affair in order of highest potential to lowest. Gas, Liquid, Solid eastward-Lab: one) Open PhET simulation States of Affair. 2) The get-go of the lab starts with Neon in a solid state at 13 Chiliad. (Kelvin (K) is a unit of temperature like Celsius and Fahrenheit). You can rut or cool the substances in the container by sliding the bar on the bucket to Heat (for fire) or Absurd (for ice). Slide the bar to Absurd and cool the neon to 0 Chiliad (this will have a while). a) The atoms are … A) non moving. A B) vibrating near a fixed position. C) sliding past each other. D) moving independently effectually the container. b) Is this physically possible (think Third Law of Thermodynamics)? No c) Become up to the tab that says "teacher" and alter the temperature scale from Kelvin to Celsius. According to this 0 Thou = __-273___ºC. Alter the scale back to Kelvin. d) Observe the pattern of the atoms relative to each other. This pattern can best be described as A) rectangular B) hexagonal B C) octagonal D) baggy (random or no design) This design is the solid Neon'southward crystalline structure. three) Click on the "Solid" push button on the right of the page. This puts the Neon'southward temperature back to 13 1000. What is this temperature in Celsius? -260 a) The atoms are … A) non moving. B) vibrating well-nigh a stock-still position. B C) sliding past each other. D) moving independently around the container. b) Are the atoms nevertheless in their crystalline blueprint fifty-fifty though they're moving? Yes they are 4) Heat the solid Neon to twenty K. What is this temperature in Celsius? -253 a) What happens to the movement of the atoms? It increase b) Are the atoms still in the crystalline pattern? Aye 5) Heat the Neon to xxx K. What is this temperature in Celsius? -243 a) The atoms are … A) not moving. B) vibrating about a fixed position. C) sliding past each other. C D) moving independently around the container. b) What state does this represent? Liquid Every now then one cantlet gains enough energy to break free from the group. This is called a vapor. 6) Heat the Neon to 60 Yard. What is this temperature in Celsius? -213 a) The atoms are … A) not moving. B) vibrating most a fixed position. C) sliding past each other. D) moving independently around the container. D b) What state is this? Gas c) Are all of the atoms moving at the same speed? No d) Does i individual atom e'er go the aforementioned speed? No e) Temperature corresponds to the _____average____ KE (or speed) of the atoms. seven) Rut the Neon to 120 Thou. a) On boilerplate, the speed of the atoms is _____B______ the speed of the atoms at 60 Grand. A) half B) twice C) sixty times D) the same as 8) Await at water every bit a gas. The molecules now have two types of motion. Linear and ____Rotational_____. 9) Look at water as a solid. Find the pattern. Now look at Neon, Argon, and Oxygen as a solid. What practice you notice in terms of the space between the particles? Water has the nearly space between particles x) Most substances compress when they freeze from a liquid into a solid, but because of h2o'south unique shape, when information technology freezes it really _____expands_______. 11) 0ºC = ____273_____ K 100ºC = ____373_____ Chiliad ten ºC = ____x+273____ One thousand
