A flask of volume 840ml contains air.it is heated up to 50 degree celciusand sealed.the flask is then cooled to 30 degree celcius,immersed in water and opened .assuming the pressure to be constant,how much water can be poured into the flask?

Dear Student,

At constant pressure,V1T1=V2T2Here, V1=840 mlT1=50°CT2=30°CTherefore, V2=V1T2T1=840×3050=504 ml
