A flask is of the capacity of 1L. What volume of air will escape from the flask it is heated from 27*C to 37*C? Assume pressure is constant.

Answers (1)

\\$\mathrm{T}_{1}=27^{\circ} \mathrm{C}=300 \mathrm{k}, \mathrm{T}_{2}=37^{\circ} \mathrm{C}=310 \mathrm{k}$ \\ \text{At Constant pressure, } \mathrm{V}_{1} / \mathrm{T}_{1}=\mathrm{V}_{2} / \mathrm{T}_{2}$ \\ $1 / 300=V_{2} / 310 \quad v_{2}=1.0333$ litre \\ since capacity of flask is one litre Volume of air escaped out: \\ $=1.0333-1=0.0333$ litre $=33.3 \mathrm{m}$
