[1] Suyuqliklardagi tovush tezligi harorat ozgarishi bilan ozgaradi. Kopgina suyuqliklarda bu korsatkich harorat ortishi bilan kamaya boshlaydi. 1 C harorat ozgarishiga mos keluvchi tovush tezligi ozgarishi, tovush tezligininh harorat koefitsienti bilan aniqlanadi. Ushbu korsatkich oldida turgan minus ishorasi, suyuqlik harorati ortishi bilan unda tovush tezligi kamayishini ifodalaydi. Suvdagi tovush tezligining harorat koefitsienti musbat. Unda harorat ortsa, tovush tezligi ham ortadi. Chuchuk suvda tovush tezligi 74 C haroratda maksimal qiymatga ega boladi.

I'm not sure exactly why but this weblog is loading very slow for me.

Is anyone else having this issue or is it a problem
on my end? I'll check back later and see if the problem
still exists.

May I simply just say what a comfort to discover somebody
who really knows what they're talking about over the internet.
You actually understand how to bring an issue to light and make
it important. More and more people need to check
this out and understand this side of the story.
I was surprised you're not more popular since you surely possess the gift.
