The volume of gas in a balloon is 1.90 L at 21.0o C. The balloon is heated, causing it to expand to a volume of 5.70 L. What is the new temperature of the gas inside the balloon?

The new temperature of the gas inside the balloon : 609 °C

When the gas pressure is kept constant, the gas volume is proportional to the temperature  

The balloon is heated, causing it to expand (pressure constant) :

V₁=1.9 L

T=21+273=294 K

V₂=5.7 L

sorry i was late, but i don't know what assignment your talking about, i'm in flvs as well, im in earth space science. but u are behind pace bc every class should be in the 3's or 4'

10 years is the answer
