In an isothermal process, the temperature of body always same throughout the process. As the internal energy of a system depends only on its temperature, thus there is no modificat
3 scenarios: You have an object such as a jar, and you submerge it under water to 50m depth. (Every 10m down increases pressure by 1 bar, thus the pressure is 5 bar). Scenario 1:
can electrons from an electron gun produce electricity
Mercury: Atomic number 80 Symbol Hg
Why does heated air expand? Temperature is often explained as the average thermal energy of the substance at hand. Therefore the hotter a substance is the more thermal energy i
