PIPE Fuels and Combustion Pt. 2

During the fusion process, mass is loss to energy according to:

• the Heisenburg uncertainty principle

• the Compton's law

• Einstein's law

• The second law of thermodynamics

A finely divided carbon deposit by the smoke of flame is called:

• fly ash

• Soot

• Residue

• All of the above

Rare gases such as helium, argon, krypton, xenon and radon that are non-reactive are called:

• Non-reactants

• Stop gases

• Inert gases

• Residual gases

Kinematics and dynamic viscosity vary from each other only by a factor equal to the :

• fluid density

• temperature

• pressure

• specific gas constant

The following properties are different for isomers of the same chemical compound except:

• density

• melting point

• number of atoms in a mole of each isomers

• specific heat

Atomic weights of the elements in the periodic table are not whole numbers because of:

• the existence of isotopes

• imprecise measurements during the development of the periodic table

• round-off error in calculating atomic weights

• the exchange of reference of the atomic mass unit from oxygen - 16 to carbon- 12 in 1961

The tendency of a pure compound to be composed of the same elements combined in a definite proportion by mass.

• Avogadro's law

• Boyle's law

• The law of definite proportions

• Le Chatelier's principle

• Gas scrubbing

• Gas purifying

• Gas liquifying

• Gas bubbling

What is the effect of a catalyst in chemical reaction?

• absorb the exothermic heat of reaction

• provide the exothermic heat of reaction

• lower the activation energy

• provide the heat of sublimation

The relationship between the concentration of products and reactants in a reversible chemical reaction given by

• the ionization constant

• the equilibrium constant

• the solubility product

• Le Chatelier's principle
