Similarly,

The correct answer is Mercury.

Key Points

• Mercury is used in thermometers because it remains in liquid form throughout a wide range of temperatures i.e -37.89 degrees Fahrenheit to 674.06 degrees Fahrenheit.
• The mercury thermometer was invented by physicist Daniel Gabriel Fahrenheit in Amsterdam.
• Mercury has a greater coefficient of thermal expansion than alcohol. 
• A thermometer with alcohol is used to measure low temperature because its freezing point is low i.e -1170C.
• It is Impossible to measure high temperatures because it’s a low boiling point.
• The thermometer with mercury cannot be used to measure the very low temperature because its freezing point is high i.e -400C.
• Mercury is the only one in liquid state at room temperature.
• It's used in thermometers because it has a high coefficient of expansion.
• It also has a high boiling point which makes it very suitable to measure higher temperatures. 
• It has a shiny appearance and doesn't stick to the glass surface of the glass.

The correct answer is Magnesium Sulfate.

• Magnesium Sulfate is the industrial name of Epsom.
• Magnesium sulfate is a magnesium salt having sulfate as the counterion.
