Dlí Charles (brú tairiseach) – fadhbanna agus réitigh

1. In a closed container, the gas expands so that the final volume becomes 3 times the initial volume (V = initial volume, T = initial teocht). What is the final temperature?

Ar a dtugtar:

Toirt tosaigh (V1) = v

Toirt deiridh (V2) = 3V

Initial temperature (T1) = T

Teastaíonn: Final temperature (T2)

Réiteach:

2. Médeal 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…

Ar a dtugtar:

Toirt tosaigh (V1) = v

Initial temperature (T1) = T

Final temperature (T2) = 2T

Teastaíonn: final volume (V2)

Réiteach:

Charles's law (constant pressure) - problems and solutions 2

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…

Ar a dtugtar:

Toirt tosaigh (V1) = 2 liters = 2 dm3 = 2 × 10-3 m3

Toirt deiridh (V2) = 3 liters = 3 dm3 = 3 × 10-3 m3

Initial temperature (T1) =27oC + 273 = 300 K

Ag Teastáil: Final temperature (T2)

Réiteach:

Charles's law (constant pressure) - problems and solutions 3

The final temperature is 177oC or 177 + 273 = 450 Kelvin.
