Question

A flask of capacity 2 L is heated from $35 ^ { 0 } \mathrm { C }$ to . What volume of air will escape from the flask?

• A. 10 mL
• B. 20 mL
• C. 60mL
• D. 50mL

Answer 1

Answer: (C)

60mL

Answer 2

:

$\mathrm { v } _ { 1 } = 2 \mathrm {~L} , \mathrm {~T} _ { 1 } = 35 + 273 = 308 \mathrm { k }$

$\mathrm { v } _ { 2 } = ? , \mathrm {~T} _ { 2 } = 45 + 273 = 318 \mathrm { k }$

Capacity of flask = 2 L

Volume of air escaped = or 60 mL
