Question
(1).
In the compression chamber of a diesel engine the volume of a gas mixture initially at 27 C is compressed by
a factor of 20(VFinal = 1/20VInitial). If the pressure increases from 1 atmosphere to 50 atmospheres, what is the final
temperature?
the answer is 477 C but i don't know the steps to get this answer. can you show all the work?
(2).
A misshapen lump of metal is weighed in air and then weighed while immersed in oil of density 800 kg/m^3 .If the weight in air is 2.2 kg and the weight in the oil is 1.2 kg, calculate the density of the metal.
the answer is 1760 kg/m^3 but i also need help on how to get this answer!
Thanks!
Explanation / Answer
p1v1/T1 =p2v2/T2
T2= 750 K
750-273= 477 C
mass of oil material in volume of bulb = 2.2-1.2 =1 kg
volume of bulb = 1/800 m^3
density =2.2*800kg/m^3
=1760 kg/m^3
