प्रश्न

A small bubble rises from the bottom of a lake where the temperature and pressure are 6°C and 4 atm. to the water surface, where the temperature is 25°C and pressure is 1 atm. Calculate the final volume in (mL) of the bubble, if its initial volume is 1.5 mL.

उत्तर

T1 = 6°C + 273 = 279 K

P1 = 4 atm

V1 = 1.5 ml

T2 = 25°C + 273 = 298 K

P2 = 1 atm

V2 = ?

`("P"_1"V"_1)/("T"_1) = ("P"_2"V"_2)/("T"_2)`

V2 = `("P"_1"V"_1)/("T"_1) xx "T"_2/"P"_2`

= `(4  "atm" xx 1.5  "ml" xx 298  "K")/(279  "K" xx 1  "atm")`

V2 = 6.41 ml
