apply quantum theory to, especially form into quanta, in particular restrict the number of possible values of (a quantity) or states of (a system) so that certain variables can assume only certain discrete magnitudes.
Answer:
State functions are Temperature, Enthalpy, Energy, Internal Energy and Adiabatic work.
Explanation:
a) State functions are those thermodynamic functions which depends only on the final and initial state of the system but not on the path followed.
From the given options only heat is not a state function.
b) (i) Reversible Process is the process which can be reversed at any point by making even very small changes in the properties of the system.
(ii) Enthalpy is defined as the total heat content of the system. It can also be written as the sum of internal energy and product of pressure and volume of the system.
(iii) Entropy defines the extent of randomness in any system.
So, a substance in gaseous state has more entropy than its liquid state as gaseous particles can more freely.
(iv) Internal Energy is the energy that involves both potential and kinetic energy of the system. It involves energy for all sorts of random motions of the particles.
(v) Isentropic processes are processes in which entropy remains constant or entropy change is zero during the process.
(vi) Adiabatic processes are those process in which there is no heat change in the process. For example in thermos flask, there is no exchange of heat between system and surroundings.
Answer:
3.
Explanation:
- Al(OH)₃ reacts with HCl to produce AlCl₃ and water according to the balanced equation:
<em>Al(OH)₃ + 3 HCl → AlCl₃ + 3H₂O,</em>
<em></em>
<em>It is clear that 1.0 mole of Al(OH)₃ reacts with 3.0 mole of HCl to produce 1.0 mole of AlCl₃ and 3.0 moles of H₂O,</em>
<em />
<em>So, the coefficient of HCl is 3.</em>
