Hi Akhl, 

I have the same question as Miggi however I was unable to answer it. It appears I cannot attach the image onto this document. It is simply a diagram of a manometer that has water.that is closed at one end and has a flask filled with gas at the other. The other value on the diagram is 1.0 cm, im not sure how you can use that. Thank you in advance :)

An experiment makes use of a water manometer attached to a flask.  Initially the two columns of water in the manometer are at the same level and the air pressure in the flask and both sides of the manometer is 1 atm.  The experiment is set up when the air temperature is 7 ?C.  As shown, the left side of the manometer is connected to the flask and the right side is capped so that the air at that end will be compressed when the flask is heated by a gas burner.  The cap is initially 15 cm above the water column (the accompanying diagram is not to scale for this).  The volume of the flask is 1 x 10^4 m3.  When calculating the change in the pressure associated with the heating of the gas in the flask, you can neglect the change in volume of the gas (air in this case) associated with the displacement of the water column in the manometer.  Calculate how many calories (cal) have been added to the flask through heating from the gas burner, given that the specific heat of the air is 20.8 (J/K)/mol. (Hint: use the ideal gas law to figure out the pressure change in both sides of the manometer tube: in one case the pressure is changing through temperature and in the other it is changing through compression.  Once you have the pressure change you can get the temperature change in the flask. Once you have that, you can figure out how much heat (Joules and then calories) has been added to the air in the flask).

@Miggi,
If you can, then post the solution to the manometer problem so that others can benefit from it. I somehow do not understand the problem itself.

Can you suggest some examples of bad interface design? The examples may be of household items or anything which is in commonly used, but it should not be software.

Please give some examples in which some features are either difficult to use or not evident for first time users.
