•  The dipole moment is found in? water
•  The amount needed to increase the temperature of one mole called? Molar heat

capacity

 If we bring any change at equilibrium the system compensate for change this is called?

•  The mass/mass percentage is among the--- CHNOLOGY 3RD Relative amounts
•  The quantitative study and measurement of heat and enthalpy changes is known as thermochemistry.
•  Density and pressure are examples of is. Intensive thermodynamic property
•  The system in which heat change is positive is? Exothermic
•  For a system in mechanical equilibrium, the pressure throughout the system is uniform and equal to the pressure of the surroundings.
•  Importance of this law: it allows us to calculate absolute entropies for substances
•  " It is impossible to reach a temperature of absolute zero."
•  The quantitative study of heat changes is ......... Calorimetry
•  Oxidation of gold....... Non spontaneous process
•  Gibbs energy free is ........ state function
•  Throttling is an example of........ irreversible process
•  Calorimeter is ......... device for measuring the heat developed during a mechanical, electrical, or chemical reaction and for calculating the heat capacity of materials
•  ▪ice calorimeter is used to determine .......... heat capacities of liquids and solids, as well as the heats of certain reactions.
•  A large number of experiment have determined that_4_variables are sufficient to define the physical condition of a gas?
•  Mechanical Equilibrium: No unbalanced forces act on or within the system; hence the system undergoes no acceleration, and there is no turbulence within the system
•  Wo Jo four colligative properties ha na us me sey two mcqs aye thy molar or molal pouch rhy thy osmotic pressure or freezing points ka

Le Chateliers Principle.

•  If ∆G is positive number the said reaction is?? Nonspontaneous ..

•  Throttling is an example of irreversible.
•  Quantitave study of heat change is called thermochemistry
•  aik water ki koi value pochi thi ans 41tha
•  Defination of Zeroth law: Two systems that are each found to be in thermal equilibrium with a third system will be found to be in thermal equilibrium with each other.
•  No unbalanced forces act on or within the system : Mechanical Equilibrium:
•  The macroscopic part of the universe under study in thermodynamics is called the

System

•  The change in enthalpy is then equal to the heat transferred at constant (pressure)
