650 APPLIED SCIENCES mercury and its temperature raised to 100 Find its final volume י Describe Regnault's hygrometer and illustrate by an example the mode of using this instrument to determine the hygrometric state of the air 500 grammes of copper specific heat 094 at 100 are plunged into 500 grammes of water at 10 20 grammes of steam at 100 are now condensed in the water and finally 40 grammes of ice are added Determine the temperature of the water at each stage How many gramme-degrees of heat will be conducted in an hour through each square centimetre of an iron plate centimetre thick its two sides being kept at the respective temperatures 100 and 300 and the mean specific thermal conductivity of iron between these temperatures being e12 IV flRtcfamc SECOND AND THIRD YEARS The same Paper as in the Department of General Literature and Science FIRST YEAH Explain why bodies of different weight fall at the same rate Through what height must heavy body fall from rest in order to acquire velocity of 322 feet per second If it continue falling for another second after having ac- quired the above velocit through what distance will it fall in that time balloon has been ascending vertically at uniform rate for seconds and stone let fall from it reaches the ground in seconds find the velocity of the balloon and the height from which the stone is let fall Show how Attwood's machine may be used to prove
