A sample of hydrogen gas occupies a volume of 6.38 L at 48.0°C and 0.490 atm. If it is desired to increase the volume of the gas sample to 8.10 L, while increasing its pressure to 0.655 atm, the temperature of the gas sample at the new volume and pressure must be °C.

The final temperature 271.77 °C

Explanation:

Given:

Initial pressure atm

Final pressure atm

Initial temperature 48° C = 321 K

Initial volume L

Final volume L

From ideal gas equation,

      K

      271.77°C

Therefore, the final temperature 271.77 °C

idk what the question is about

air

in a tire you fill a tire with air

then a couple days later you check the air pressure in the tire

hope this mark me brainliest
