what will be the change in volume of 30m^3 gas if itr temp is reduced 3 times ??​

what will be the vol of an air bubble at the surface of water if its vol is 20 dm^3 at bottom where pressure is 3 times the atmospheric pressure ?? ( Po = 1*10^5 Pa)​

what will be the sp. heat capacity of a 20g metal at 120degreeC if immered into 50g water at 30degreeC ????​

c for water = 4200J/kgK​

1. Volume will decrease as they are directly proportional
2.use the p1v1 = p2v2 formula here
3.Q=Mc X change in temperature??

use the V1/ T1= V2/ T2

P1V1=P2V2

Q=mc* temp change

 

[Spidey21]

use the V1/ T1= V2/ T2

P1V1=P2V2

Q=mc* temp change

i win by 6 minutes!!
