The following term has to be defined – Evaporation Concept introduction: Evaporation is the phenomenon involving phase change. It is the transition of liquid to vapor state. This process is applicable to liquids. Evaporation can either occur spontaneously at room temperature or by inducing changes in energy of the molecules. The liquids that evaporate spontaneously at room temperature are called volatile liquids. The liquids that do not evaporate readily and require external energy to undergo evaporation are called non-volatile liquids. It is an endothermic phenomenon.

Interpretation Introduction
Interpretation:
The following term has to be defined –
Condensation
Concept introduction:
Condensation is a process involving phase change. The molecules in vapor phase transit to liquid phase in this process releasing heat to surroundings.
(c)
Interpretation Introduction
Interpretation:
The following term has to be defined –
Sublimation
Concept introduction:
Sublimation is a process of conversion of solid molecules directly to vapor molecules. That is, direct vaporization of solid without the involvement of any intermediate phase. It is an endothermic process.
(d)
Interpretation Introduction
Interpretation:
The following term has to be defined –
Boiling
Concept introduction:
Boiling is the applicable to liquids and an endothermic process. It is a process used to vaporize a liquid. It is familiar that evaporation is accompanied by heating the liquid to boil.

Interpretation Introduction
Interpretation:
The following term has to be defined –
Melting
Concept introduction:
Melting is the process applicable to solids and it is an endothermic process. Solid converts to liquid during melting.
(f)
Interpretation Introduction
Interpretation:
The following term has to be defined –
Enthalpy of vaporization
Concept introduction:
The term enthalpy means heat content. Vaporization means conversion to vapor. Thus enthalpy of vaporization is the heat required by a liquid substance to convert itself completely to vapor.
(g)
Interpretation Introduction
Interpretation:
The following term has to be defined –
Enthalpy of fusion
Concept introduction:
Enthalpy of fusion is the heat required by a solid substance to convert to liquid phase.
(h)
Interpretation Introduction
Interpretation:
The following term had to be defined –
Heating curve
Concept introduction:
Heating curve is a graphical representation used to observe the heating process over a period of time.
A block of zinc has an initial temperature of 94.2 degrees celcius and is immererd in 105 g of water at 21.90 degrees celcius. At thermal equilibrium, the final temperature is 25.20 degrees celcius. What is the mass of the zinc block? Cs(Zn) = 0.390 J/gxdegrees celcius Cs(H2O) = 4.18 J/gx degrees celcus

1. Consider these three reactions as the elementary steps in the mechanism for a chemical reaction.
AH = -950 kJ
AH = 575 kJ
(i) Cl₂ (g) + Pt (s) 2C1 (g) + Pt (s)
Ea = 1550 kJ
(ii) Cl (g)+ CO (g) + Pt (s) → CICO (g) + Pt (s)
(iii) Cl (g) + CICO (g) → Cl₂CO (g)
Ea = 2240 kJ
Ea = 2350 kJ
AH = -825 kJ
