**Q.3**. Read the following paragraph :

"The ordinary form of mercury thermometer is used for temperature ranging from —40^{o}F to 500^{o}F. For measuring temperature below —40^{o} F, thermometers filled with alcohol are used. These are, however, not satisfactory for use in high temperatures. When a mercury thermometer is used for temperature above 500^{o}F, the space above the mercury is filled with some inert gas, usually nitrogen or carbon dioxide, placed in the thermometer under pressure. As the mercury rises, the gas pressures is increased, so that it is possible to use these thermometers for temperatures as high as 1000^{o}F."

With what, besides mercury, would a thermometer be filled if it was designed to be used for measuring temperature of about 500^{o}F?

(A) Pyrometer (B) Inert gas (C) Iron and brass (D) Gas
