As a heating technology, Joule heating has a coefficient of performance of 1.0, meaning that every joule of electrical energy supplied produces one joule of heat. In contrast, a heat pump can have a coefficient of more than 1.0 since it moves additional thermal energy from the environment to the heated item.
Vietnam had the fastest growth in coal use in Southeast Asia during 2011-2021, at an annual growth rate of 11%. [4]Data of the Ministry of Industry and Trade (MOIT), 10 months of 2018 coal production was estimated at 34.35 million tons, up 10% over the same period in 2017, of which clean coal output of Vinacomin (TKV) was 29.6 million tons, up 10.9% over the same period last year.

Joule heating, process by which the passage of a current through a conductor releases heat; joule per mole (J/mol), an SI derived unit of energy per amount of material; joule-second (J∙s), a unit used to measure action or angular momentum; joule/second (J/s), another term for the watt; Joule thief, a minimalist self-oscillating voltage booster
Originally, many thước of varying lengths were in use in Vietnam, each used for different purposes. According to Hoàng Phê (1988), [1] the traditional system of units had at least two thước of different lengths before 1890, [2] the thước ta (lit. "our ruler") or thước mộc ("wooden ruler"), equal to 0.425 metres (1 ft 4.7 in), and the thước đo vải ("ruler for measuring ...
In thermodynamics, the Joule–Thomson effect (also known as the Joule–Kelvin effect or Kelvin–Joule effect) describes the temperature change of a real gas or liquid (as differentiated from an ideal gas) when it is expanding; typically caused by the pressure loss from flow through a valve or porous plug while keeping it insulated so that no heat is exchanged with the environment.
Việt-nam bách-khoa từ-điển (Encyclopedia of Vietnam), a set of encyclopedias with annotations in Chinese, English and French by Đào Đăng Vỹ, a Vietnamese scholar; published from 1959 to 1963 in Saigon, Republic of Vietnam. [3] [4]
Vietnam Electricity (EVN; Vietnamese: Tập đoàn Điện lực Việt Nam, lit. 'Vietnam Electricity Group') is the national and the sole public power company in Vietnam. It was established by the government of Vietnam as a state-owned company in 1994, and has operated officially as a one-member limited liability company since 2010. [2]
