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.

In May 2023, the country experienced an unprecedented heatwave where sections of the country registered temperatures over 40 °C. One recording saw the weather reach a record high 44.1 °C at the Hoi Xuan station, breaking the 43.4 °C record set in 2019 according to the National Centre for Hydro Meteorological Forecasting.

The use of the words "latent heat" implied a similarity to latent heat in the more usual sense; it was regarded as chemically bound to the molecules of the body. In the adiabatic compression of a gas, the absolute heat remained constant but the observed rise in temperature implied that some latent caloric had become "free" or perceptible.
An air source heat pump (ASHP) is a heat pump that can absorb heat from air outside a building and release it inside; it uses the same vapor-compression refrigeration process and much the same equipment as an air conditioner, but in the opposite direction. ASHPs are the most common type of heat pump and, usually being smaller, tend to be used ...
An example of a new source of heat "turning on" within an object, causing transient conduction, is an engine starting in an automobile. In this case, the transient thermal conduction phase for the entire machine is over, and the steady-state phase appears, as soon as the engine reaches steady-state operating temperature .
In physics and engineering, heat flux or thermal flux, sometimes also referred to as heat flux density [1], heat-flow density or heat-flow rate intensity, is a flow of energy per unit area per unit time. Its SI units are watts per square metre (W/m 2). It has both a direction and a magnitude, and so it is a vector quantity.
