The state of bromine is liquid at room temperature.

Explanation:

We are given that room temperature is around $25^{\circ}C$

We have to find out the state of bromine at room temperature at $25^{\circ}C$

We change celsius into kelvin by the formula

kelvin measure= 273+ celsius measure

Therefore $25^{\circ}$ C= 273+25=298 k

The attraction forces between the molecules of bromine is dispersion force.The dispersion force is the weakest intermolecular forces. it is a temporary attractive force.The molecules of bromine hold together with strong dispersion forces. Therefore, room temperature is not sufficient to overcome the strong dispersion forces . It requires more energy to break the substance . Therefore, the state of bromine is liquid at room temperature.

The state of bromine is liquid at room temperature.

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
