A Glass Flask Has a Volume of 500 ML $20 ^ { \circ } \mathrm { C }$

question 17

Multiple Choice

A glass flask has a volume of 500 mL at a temperature of $20 ^ { \circ } \mathrm { C }$ The flask contains 492 mL of mercury at an equilibrium temperature of $20 ^ { \circ } \mathrm { C }$ The temperature is raised until the mercury reaches the 500 mL reference mark. At what temperature does this occur? The coefficients of volume expansion of mercury and glass are $18 \times 10 ^ { - 5 } \mathrm {~K} ^ { - 1 }$ (mercury) and $2.0 \times 10 ^ { - 5 } \mathrm {~K} ^ { - 1 } \text { (glass) }$

• A) \(110 ^ { \circ } \mathrm { C }\)
• B) \(100 ^ { \circ } \mathrm { C }\)
• C) \(140 ^ { \circ } \mathrm { C }\)
• D) \(130 ^ { \circ } \mathrm { C }\)
• E) \(120 ^ { \circ } \mathrm { C }\)
