Ndeipi maitiro ekubikira?
Iko kuwedzera kwekuvira (uye nzvimbo inonyungudika) kunogona kuverengerwa nekuwedzera kwema intermolecular mauto (van der Waals). Kuwanda kwemaerekitironi kunowedzera mune chimwe nechimwe chinhu chichienda pasi neboka, izvi zvinotungamira mukuwedzera kwezvidimbu dipoles zvinogona kumisikidzwa.
Ndezvipi zvinhu zvine mapoinzi akanyanya uye anofashaira?
Kana pasina manyukireya mvura inogona kuvapo semvura yakatonhodzwa zvikuru kusvika -48.3 °C (−54.9 °F; 224.8 K) isati yatonhora. Kemikari ine nzvimbo yepamusoro yekunyungudika ndeye tungsten, pa3,414 °C (6,177 °F; 3,687 K); ichi chivakwa chinoita tungsten yakanakira kushandiswa semagetsi mafilaments mumarambi eincandescent.
Vanonwa doro vane nzvimbo dzakakwirira dzekuvira here?
Mapoinzi ekubikisa edoro akakwirira zvakanyanya kupfuura eaya alkanes ane zviyero zvakafanana zvemamorekuru. … Musiyano uyu wakawanda unobva mukugona kwe ethanol nezvimwe zvinwiwa kuumba intermolecular hydrogen bond. (Ona kemikari bonding: Intermolecular forces yehurukuro yehydrogen bonding.)
Ndeupi mukomboni une pozoti yakadzika kwazvo?
