Choose the correct answer (It's impossible for a heat engine 1 point to produce net work in a complete cycle if it exchanges heat only with bodies at a single fixed temperature). this statement refer to: 2nd law of thermodynamics Zeroth law of thermodynamics 1st law of thermodynamics Gibss Dalton law (The internal energy of a perfect 1 point gas is function of the absolute temperature only) this statement refer to: Zeroth law of thermodynamics Joule law Dalton law First Law of thermodynamics When a liquid is heated at any one constant pressure there is one fixed temperature at which bubbles of vapour form in the liquid, this phenomenon is known as: 1 point Heating Boiling Saturation Mixing 0.05 kg of Steam contained in a 1 point rigid vessel of volume 0.00755 m3 with a pressure 20 bar. The temperature of steam will be: 350 °C 425 °C ○ 400 °C 375 °C Energy has different forms which 1 point include: None of the mentioned All of the mentioned Work ○ Heat When two systems have equality 1 point of temperature witha third system, they in turn have equality of temperature with each other. Zeroth law of thermodynamics Gibss Dalton law 1st law of thermodynamics 2nd law of thermodynamics
