Question 1

Intermolecular force

Answer 1

Force between two molecules

Question 2

Hydrogen bonds take place with

Answer 2

Nitrogen ,oxygen , and Florine

Question 3

Viscosity

Answer 3

Measure of the fluids resistance to movement

Question 4

Service tension

Answer 4

The measure of elastic forces within the surface of a liquid

Created by the side ways and downwards forces exerted on the molecules on the surface of a liquid

Question 5

Vapor pressure

Answer 5

Pressure exerted on a liquid by the molecules that have escaped the liquid phase to gas phase

Higher the vapor pressure the lower the boiling point

Question 6

Unit cell

Answer 6

Basic repeating structural unit of a crystalline solid

Question 7

Lattic point

Answer 7

Corner point or connection point of molecules in a lattice structure

Question 8

Types of unit cells

Answer 8

Simple cubic, tetragonal, orthorhombic, rhombohedral, monoclinic, triclinic, hexagonal,

Question 9

Types of cubic cells

Answer 9

Simple , body centered, face centered

Question 10

Simple cubic radius equation

Answer 10

a=2r

Question 11

Body centered radius equation

Answer 11

a=4r/squrt(3)

Question 12

Face centered radius equation

Answer 12

a=squrt(8)r

Question 13

Brag equation

Answer 13

Wave length = 2dsin(thata)

Question 14

Clausius- Clapeyron equation

Answer 14

ln(P) = -(delta H/RT) + C

ln(P1/P2) = delta H/ R( (1/T1) (1/T2) )

Question 15
