1. In a closed container, the gas expands so that the final volume becomes 3 times the initial volume (V = initial volume, T = initial wela). What is the final temperature?
ʻIke ʻia:
Ka nui mua (V1) = V
Ka leo hope loa (V2) = 3V
Mahana mua (T1) = T
Makemake: Mahana hope loa (T2)
Lōlā:
ʻO ke kumu o Charles’s law :
The final temperature of gases becomes 3 times the initial temperature.
2. ʻO waudeal 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…
ʻIke ʻia:
Ka nui mua (V1) = V
Mahana mua (T1) = T
Mahana hope loa (T2) = 2T
Makemake: final volume (V2)
Lōlā:
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…
ʻIke ʻia:
Ka nui mua (V1) = 2 lita = 2 dm3 = 2x10-3 m3
Ka leo hope loa (V2) = 3 lita = 3 dm3 = 3x10-3 m3
Mahana mua (T1) = 27oC + 273 = 300 K
Makemake ʻia: Mahana hope loa (T2)
Lōlā:
The final temperature is 177oC or 177 + 273 = 450 Kelvin.
