Snoopy is inflated for the Macy’s Thanksgiving parade with 50,000 L of He at 25 oC and 1.2 atm. What is the percent decrease in Snoopy’s volume if the temperature drops to 4 oC before the parade? Assume constant pressure.

D.V.= - 1.34 %

Explanation:

Given that

V₁=50,000 L

T₁=25⁰C = 273 + 25 K =298 K

The final temperature ,T₂= 25 - 4 ⁰C = 21 ⁰C

T₂ = 21 + 273 K= 294 K

We know that for constant pressure process

V₂=49328.85 L

The percent decrease in the volume is given as

D.V.= - 1.34 %

i don't understand really? can u provide more information

u should make a machine that can make ice cream fresh!
