Define Heat engine
Heat engine is a device by which a system is made to undergo a cyclic process that results in conversion of heat into work.
It is explained as the ratio of useful work done (W) to the heat input.
1. The probability of dissociation of water into H + and OH - , to a good approximation, can be characterized by the Boltzmann distribution: W ≈ e -Eα/ KT If, at 27°C, 1.
Evaluate frequency to shatter the glass with a resonant vibration? Standing-wave vibrations are set up in a crystal goblet with four nodes and four antinodes equally spaced arou
It is the property of changing readily from a solid or liquid to a vapour. It is the speed that a chemical compounds evaporates. Higher volatility indicates faster evaporation.
Two light rays will interfere constructively with maximum amplitude if the path difference between them is: a) one wavelength b) one-half wavelength c) one-qua
