Question:I am talking about solid, liquid, and gas for all entire periodic table. I am not including ones that exist for less than a few minutes or seconds.
Answers:Hi: Arsenic (As; Z= 33) sublimes at 1.00 atm at 615 C; under 38.6 atm it melts at 816 C. Iodine (I2, Z =53) comes close to subliming at its mp of 113.6 C: the vapor pressure of I2 at that T is 90.5 mmHg. drp
Added later: Unlike any other element, helium will remain liquid down to absolute zero at normal pressures (see answer above).
Question:Can all elements take the all of the 3 basic states of matter? Like, could you find solid oxygen or a gaseous form or Uranium?
Answers:Yes, depending on the temperature and pressure.
They have not solidified hydrogen, but it should around absolute zero under great pressure.
Some of the elements sublime and turn directly from a solid to a gas.
Some of the elements it would take an extremely high temperature to cause them to be a gas.
Question:1. What characteristcs do all samples of matter have in common?
2. What is the difference between an element and a compound?
3. Name four states of matter.
4.Which states of matter have no definate shape?
3. How does the space between particles of a solid change when it becomes a liquid?
2.Element is single but a compound has at least two elements.
5.two atomics diameters.
Question:My groupe jose and I have to make a presentation to the class about matter. We both have to speak and be included. We have to teach the class 3 states of matter but plasma is optional. We have all the stuff we need but we dont know exactly how to put it in a presentation with both of us speaking and showing the class. We also want to know how to incorperate an activity in it and all of this has to be done within like in no time at all. ANy ideas?
Answers:Bring in an ice cube, a small glass dish, and some type of Bunsen burner. Show how the ice cube starts as a solid, melts to a liquid, and then evaporates as it boils to a gas. If you bring in a jug, or thermos with a lot of ice in it, then you should have plenty of unmelted ice cubes to work with. If your class is at the end of the day, ask someone in the cafeteria if they can keep it in the freezer for you. Each of you can take turns talking about each phase.
States of matter :A video about the four states of matter (solid, liquid, gaseous & plasmatic). The element seen in the video is hydrogen. The red speheres are protons, the blue ones are electrons and the transparent shell theyre in is supposed to be the atom shell. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Modeled and rendered it in Cinema 4D R10 All copyrights go to me.
Chemistry: States of Matter :www.mindbites.com Science is a method for categorizing the world around us. One way to do this is to categorize matter (anything that has mass and takes up space). Matter can be categorized by state (or phase) - whether it is a solid, a liquid, or a gas. A solid has a fixed shape and volume. A liqid has a fixed volume, but not shape. And a gas has neither a fixed volume or shape. In addition to its state, matter can be categorized as either pure or a mixture. Pure matter is made up of only one component. Pure substances are either elements, which are the fundamental building blocks of matter, or compunds, which are chemically bonded atoms. Mixtures are substances that can be separated by physical techniques and are either homogeneous or heterogeneous.
