A heated tobacco product (HTP) [note 1] is a tobacco product that heats the tobacco at a lower temperature than conventional cigarettes. [32] These products contain nicotine, which is a highly addictive chemical. [32] The heat generates an aerosol or smoke to be inhaled from the tobacco, which contains nicotine [33] and other chemicals.
Calcium carbonate (limestone or chalk) decomposes into calcium oxide and carbon dioxide when heated. The chemical reaction is as follows: CaCO 3 → CaO + CO 2 The reaction is used to make quick lime, which is an industrially important product. Another example of thermal decomposition is 2Pb(NO 3) 2 → 2PbO + O 2 + 4NO 2.

Crucibles are used in the laboratory to contain chemical compounds when they are heated to extremely high temperatures. Crucibles are available in several sizes and typically come with a correspondingly-sized lid. [20] When heated over a flame, the crucible is often held inside a pipeclay triangle which itself is held on top of a tripod.

Each person is given equal right to participate, as illustrated by the idea of a circular layout referred to in the term round table.

With indirect resistance heating technology, the mold is placed in a heating chamber. The chamber is heated by graphite heating elements. These elements are heated by electric current. The heat is then transferred into the mold by convection. As the electrical energy heats the heating elements that then heat the mold in a secondary manner, the ...
New York Jets team owner Woody Johnson took to social media Thursday to deny a report from an NFL Network host about a "very heated conversation" between he and head coach Robert Saleh at the ...
In semantics, pragmatics, and philosophy of language, a question under discussion (QUD) is a question which the interlocutors in a discourse are attempting to answer. In many formal and computational theories of discourse, the QUD (or an ordered set of QUD's) is among the elements of a tuple called the conversational scoreboard which represents the current state of the conversation.
