1. In a closed container, the gas expands so that the final volume becomes 3 times the initial volume (V = initial volume, T = initial hőmérséklet). What is the final temperature?
Ismert:
Kezdeti térfogat (V1) = V
Végső térfogat (V2) = 3V
Initial temperature (T1) = T
Wanted: Final temperature (T2)
megoldás:
A képlet Károly törvénye :
The final temperature of gases becomes 3 times the initial temperature.
2. éndeal gases initially have volume V and temperature T. If the gas undergoes the isobaric process so that the temperature becomes 2 times the initial temperature then the final volume of gases is…
Ismert:
Kezdeti térfogat (V1) = V
Initial temperature (T1) = T
Final temperature (T2) = 2T
Wanted: final volume (V2)
megoldás:
The final volume of gases becomes 2 times the initial volume.
3. In a closed container, ideal gases initially have a volume of 2 liters and temperature of 27oC. If the final volume of gases becomes 3 liters then the final temperature is…
Ismert:
Kezdeti térfogat (V1) = 2 liters = 2 dm3 = 2 x 10-3 m3
Végső térfogat (V2) = 3 liters = 3 dm3 = 3 x 10-3 m3
Initial temperature (T1) = 27oC + 273 = 300 K
Keresett: Final temperature (T2)
megoldás:
The final temperature is 177oC or 177 + 273 = 450 Kelvin.
