Expert Answer

Step 1

The values are given as follows:

initial volume (V,) = 0.750 L
initial temperature (7)= 20 °C
(20+273) K
= 293 K
final volume(V1.00 L
Here
1°C 273 K

Step 2

Supposed that, the pressure of the air in the balloon is constant during the procedure. The final temperature of the air in the balloon can be determined with the help of Charle’s law as follows:

Step 3

Substitute the given values into the above equation in or...

0.750 L
1.00 L
Т,
(1.00L)(293 К)
(0.750 L)
293 K
= 390.67 K
