Use the phase diagram above to answer the questions below .( remember that standard pressure is 1.00 atm and it’s used to find normal phase change temperatures.) 1: in which state/phase of matter is this substance at -10 °c and a pressure of 0.50 atm? 2: what phase change occurs as the substance at 0.75 atm is heated from 0°c to 25°c 3: the normal boiling point of a substance is the temperature at standard pressure (1 atm) in which a substance changes from the liquid to the gas/vapor state . what is the normal boiling point of this substance ? 4: the point on the phase diagram where the separation line between liquid and gas ends and the distinction between the liquid phase and gas phase disappears is called the . at this point ,no amount of pressure will cause the substance to condense into a liquid 5: what is the temperature and pressure of the triple point? what phases are in equilibrium at this point ? 6: what phase change occurs as the substance at 0°c has its pressure dropped from 0.50 atm to 0.25 atm?

Acetic acid  /əˈsiːtɪk/, systematically named  ethanoic acid  /ˌɛθəˈnoʊɪk/, is a colourless liquid  organic compound  with the  chemical formula  ch3cooh (also written as ch3co2h or c2h4o2). when undiluted, it is sometimes called  glacial acetic acid.  vinegar  is no less than 4% acetic acid by volume, making acetic acid the main component of vinegar apart from water. acetic acid has a distinctive sour taste and pungent smell. in addition to household vinegar, it is mainly produced as a precursor to  polyvinyl acetate  and  cellulose acetate. it is classified as a  weak acid  since it only partially  dissociates  in solution, but concentrated acetic acid is corrosive and can attack the skin.acetic acidnamespreferred iupac nameacetic acidsystematic iupac nameethanoic acidother namesvinegar (when dilute); hydrogen acetate; methanecarboxylic acid[1][2]identifierscas number64-19-7  3d model (jsmol)interactive image3dmetb00009 reference506007chebichebi: 15366  chemblchembl539  chemspider171  drugbankdb03166  echa infocard100.000.528ec number200-580-7e numbere260  (preservatives)gmelin reference1380iuphar/bps1058keggd00010  meshacetic+acidpubchem  cid176rtecs numberaf1225000uniiq40q9n063p  un number2789inchiinchi=1s/c2h4o2/c1-2(3)4/h1h3,(h,3,4)  key:   qtbsbxvteameqo-uhfffaoysa-n  smilescc(o)=o

No because a circle or pie graph usually shows percentages you'd need a line graph
