He carried out research in the areas of kinetic theory of gases, electrical conductivity, gas discharges, heat radiation, ferromagnetism and photochemistry.
17.
When ACSR is new, the aluminium has a shiny surface which has a low emissivity for heat radiation and a low absorption of sunlight.
18.
Infrared radiation is popularly known as " heat radiation ", but light and electromagnetic waves of any frequency will heat surfaces that absorb them.
19.
Heating and cooling of skyscrapers can be efficient, because of centralized HVAC systems, heat radiation blocking windows and small surface area of the building.
20.
