I'm sure you all know the format.

Person A asks a question, person B answers. If correct person then gets to ask the next question.

Questions should relate to the Junior Certificate exams and the syllabii.

What is Inflation?

TransititionMan

Inflation is where the economys surplus or deficit.
For example, if irelands total incoming money one year was 100 billion
and the next year it was 110 billion, the countries inflation rate wouldbe 10 percent.
A very unrealistic example but i hope none the less, it gets the point across :P

You are refering to economic growth which occurs when a countries GNP increases from one year to the next. Inflation is when there is an increase in the cost of living from one period of time to the next. Irelands inflation rate is known as the consumor price index.

how are metamorphic rocks formed?

TransititionMan

Lol thanks for the correction and thats the only short question i didnt answer with the "another name for inflation in ireland":S
Anyway back to the topic.
Metamorphic rocks are formed out of rocks that already exist. The immense pressuse and heat caused to the rocks fuse them together to form Metamorphic rocks.
Examples of this type of rock are marble quartzite and slate.

Lol forgot question :P

What is the centre of gravity?

TransititionMan

The centre of gravity is the point of an object in which its maximum balance lies. Wide, short things have high centre of gravity, thin, high things have a low centre of gravity

What is Ionic bonding?

y - y1 = m(x-x1)
where m is the slope..

I prefer the definition that "The centre of gravity of an object is the point through which all the weight of the object appears to act" (the word appears is important!)

Your statement about wide, short objects and high thin ones is not true. The location of the centre of gravity depends on where the mass is distributed in the object. A racing car, for example, has a centre of gravity which is about 1cm above the ground. A champagne flute containing liquid would have a high centre of gravity, located somewhere inside the area where the liquid is.

Transfer of Atoms!...

Ionic bonding is NOT the transfer of atoms. Ionic bonds occur between atoms which have lost/gained electrons.

The corrrect definition is "An Ionic bond is the force of attraction between oppositely charged ions in a compound" (where an ion is an atom which has lost/gained electrons, e.g. Na+, Cl-, etc)

It is!
The greater the surface on the ground, the lower the centre of gravity is,
judging of course that the shape is the same thickness throughout and is of the same density.

Now I'll answer the last question said being 1916 :P
And then write a question as it is the done thing in the pop quiz.

What does A/C & D/C stand for?

The problem is, that's the opposite to what you said in your original post -

Wide, short things have high centre of gravity, thin, high things have a low centre of gravity

What you say is true if you compare, say, the location of the C.o.G. in a skyscraper standing vertically and then the same one lying on it's side (the C.o.G. will be at a lower height when it's lying horizontally)

The definition I propose is a general one, which will always hold true. Check out online definitions of the centre of gravity - you will notice that they all pretty much say the same thing as I did.

In an exam, for a definition to be acceptable, it should be general enough to apply in ALL cases.

What is a souterrain?

I didn't reply because I'm not a Junior Cert student. I'm a science teacher with over 20 years experience of teaching science at Junior Cert and Leaving Cert level and I was trying to make the point that some of the definitions/answers given were not exactly correct. I was giving a little advice based on years of correcting exams and seeing people lose marks because of errors in their definitions/explanations.

But if you want an answer, a souterain is an artificially built underground structure usually consisting of a passageway and sometimes one or more rooms.

That's all.

I dont really care what you are you could be a phsics professor for all I care but when posting in a Junior cert thread in the junior cert forum perhaps you should not adopt a ''I'm above the petty rules'' Attitude.

Again no question posed so -What's the french for tooth-paste?

I wasn't adopting an "I'm above the petty rules" attitude - I was only trying to be helpful by commenting on mistakes in one or two answers.

Obviously my suggestions on how to gain more marks are not welcome, so I won't bother you again.
