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.
The total installations they would have completed is 64 installations
<h3>Quantity & Rate </h3>
From the question, we are to determine how many total installations they would have completed
If the technician can complete an installation in 1.5 hours
Then,
In 60 hours, the technician will complete installations
= 40
Therefore, the technician would have completed 40 installations
- For the less experienced colleague
If it takes the less experienced colleague 2.5 hours to complete an installation
Then,
In 60 hours, the less experienced colleague will complete installations
= 24
Therefore, the less experienced colleague would have completed 24 installations
Hence, the total installations they would have completed is 40 + 24 = 64 installations

Answer:
A perfect mold of a dinosaur bone
Answer:
molarity
Explanation:
Molarity is defined as the number of moles of solute in 1 liter of a solution while molality is defined as the mole of solute in 1 kg of solvent.
<em>If a solution prepared at 20 degrees celsius is heated to 88 degrees celsius, the molarity would change because the volume of a solution is temperature-dependent due to expansion or contraction. The molality, however, will not change for as long as the amount of the solvent remains unchanged due to the heating. </em>
Answer:
the motion is different.
Explanation:
the the motion is different because the particle in a book is solid particles and solid are packed together so so they can't move freely but while the the particles in the air around it is gas particles and it are packed very loose and can move very easily anywhere like .Example - solid-book , eraser. gas-helium, oxygen.
