1. In a closed container, the gas expands so that the final volume becomes 3 times the initial volume (V = initial volume, T = initial pāmahana). What is the final temperature?
Mōhiotia:
Te rōrahi tīmatanga (V1) = V
Rōrahi whakamutunga (V2) = 3V
Initial temperature (T1) = T
Hiahia: Final temperature (T2)
Rongoā:
Ko te tātai o Charles’s law :
The final temperature of gases becomes 3 times the initial temperature.
2. Ahaudeal 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…
Mōhiotia:
Te rōrahi tīmatanga (V1) = V
Initial temperature (T1) = T
Final temperature (T2) = 2T
Hiahia: final volume (V2)
Rongoā:
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…
Mōhiotia:
Te rōrahi tīmatanga (V1) = 2 liters = 2 dm3 = 2x10-3 m3
Rōrahi whakamutunga (V2) = 3 liters = 3 dm3 = 3x10-3 m3
Initial temperature (T1) = 27oC + 273 = 300 K
E hiahiatia ana: Final temperature (T2)
Rongoā:
The final temperature is 177oC or 177 + 273 = 450 Kelvin.
