لو سمحتم مساعدة ضرورررررررررررررررررررررررى:(182):: (182)::(182):
عندى 3سؤال heatممكن:(301)::(301)::(301)::(301) :
1)Two spheres are made of the same ****l and have the same radius ,but one is hollow and the other is solid. the spheres are taken through the same temperature increase .which sphere expands
more?and why?


2)what do you mean by used expression (gas equilibrium) in the first law of thermodynamics

3)A system of diatomic ideal gas at pressure 1.2 Kbar and an initial temperature of 107F slowly expand isobarically volume to 2600cm from volume 1.4L
a)find the wok done on the environment.
b)Use the molar heat capacity at constant pressure to find the thermal energy absorbed
c)find the change in internal energy of the gas
d)Use the first law of thermodynamics to obtain the thermal energy absorbed by the gas during the process.)

فين الردود ارجوووووووووووووووووووووووووووووووو وكم انا فى انتظار

First question:

They will expand equally because the material will expand same distance so, will not be different if it is solid or hallow.

Second question:

Amount of vapour condense equal to amount of gas vaporize.

Third question:

please re-write again because I think there is mistake in this sentence (isobarically volume to 2600cm from volume 1.4L).
