Ans: the specific heat of the
substance is 46.5 J/kg.
The possible advantages of above method are:
the heat capacity of the apparatus needs not be known, --all the heat from the
substance is used to melt the ice, at constant temper -ature because the tube starts at 0 o and finishes ato c.
no heat losses from the apparatus - it is surrounded by the bath at the sHUNG temperature is itself, and therefore neither loses heat to the outside,nor gains any from it.
no loss of hast from the speci -man before it enters the tube
the specimen starts at room température, and therfore loses no heat until it enters the tube. This would be a great advantage as compared with the method of mixtures when the specimen is small. easy the only temperature to be measured is the room: temperature which is fairly constant and can be measured at leisure.
vaporation is the change from liquid to vapour, therfore it includes boiling in which pro cess the vapour is in equilib- rium with the liquid. Their differences arer“
1. Evaporation takes place at
all temperatures and occurs from the liquid surface. It increases with surface area of the liquid, wind, lower relative humidity and high er liquid temperature. 2. Boiling occurs only at a
fixed temperature for: a given extern 1 atmospheric pressure, it takes place throughout the whole body... of the liquid, and is. independent of liquid surf- ace area or wind or relative humidity,

The story can also be used as an introduction to essays such as "No. Paine, No Gaina' severance etc. When such method is applied, we must be aware of the length and the appropriateness of the story itself. It is very important to give a good beginning to our composition so that we may raise the readers interest to explore the whole story.

Issue (9) Development of Theme
It is very often that we find hardly enough materials to compose an essay of 600 words. The discussion to be made is to suggest some of the N methods through which right materia- 1s can be collected to the mind. It is very important to form the main theme of our composition with useful, relevant, and clearly expressed ideas, and the way to begin our composition, to arrange and present the right materials in acceptable order, and then to bring our comp- osition to a satisfactory conclusion are the topics we are going to study together.
A. How to begin our composition:
a. By telling short stories:
Read the following short story Manfucius, one of the famous Chinese philosophersand teachers, was a lazy and naughty boy when he was young. Once he ran away from school and reached home just at the moment when his mother was busy at her weaving work. She stopped short and instead of scolding the young boy, she took up a pair of scissors to cut up the piece of cloth for which she had laboured many hours.
Not until young Manfucius asked in his curiosity why his mother destroyed the piece of cloth when it was halfly done, then the kind mother explained to her child the importance of constant hard work. The story above, for example, can be used in the introduction of many essays as long as we are able to draw it together with the topic on which we suppose to write; for example, for the topic.
Rome was not built in a Day' may put it this way:
We
the kind mother explained to her child the importance of constant hard work, Roma was not built in a day, and no task that is really worth doing can. be done quickly and easily. Many months and years of practice will be required before one can become really successful.
