Question

a balloon filled with helium has a volume of 11.8 l at 289 k. what volume will the balloon occupy at 257 k?

Answer 1

Step-by-step explanation:

289k ---- 11.8

257k ------ x (where x = volume at 257k)

x =
`(257*11.8)/(289)`

x = 10.49 I

therefore at, 257k the balloon will have a volume of 10.49
