Mercury is preferred for thermometers because it has a high coefficient of thermal expansion, making it very sensitive to temperature changes. It is also easy to see and read due to its silver color and sharp meniscus. Additionally, mercury remains in a liquid state over a wide range of temperatures.
What else can I help you with?
What is the most dangerous thermometer if it breaks?
A mercury thermometer is the most dangerous if it breaks because mercury is a toxic substance that can harm human health and the environment. If a mercury thermometer breaks, it is important to follow proper cleanup procedures to avoid exposure to the mercury.
What color is the Mercury in a Mercury thermometer?
Mercury in a Mercury thermometer is typically silver in color.
Can the mercury in a thermometer hurt you?
Yes, if a mercury thermometer breaks, the mercury can vaporize and be inhaled, which can be harmful to your health. It is important to handle and dispose of a broken mercury thermometer properly to avoid exposure to mercury.
What type of thermometer is widely used in science classrooms?
Frequently thermometers filled with an alcohol; but also thermometers with mercury, with thermoresistance, thermocouples, etc.
What causes mercury in a thermometer to rise?
The mercury in a thermometer rises because of thermal expansion. When the temperature surrounding the thermometer increases, the molecules of the mercury expand, causing it to move up the narrow tube of the thermometer.
Which thermometer is most suitable for measuring boiling point of water mercury or alcholic thermometer?
Which thermometer is most suitable for measuring boiling point of water mercury or alcoholic thermometer
What is the most dangerous thermometer if it breaks?
A mercury thermometer is the most dangerous if it breaks because mercury is a toxic substance that can harm human health and the environment. If a mercury thermometer breaks, it is important to follow proper cleanup procedures to avoid exposure to the mercury.
How does Mercury work?
Temperature affects the amount the mercury is spread out. Heat causes most liquids to expand, which is how a thermometer works. As heat around the glass protecting the mercury of the thermometer rises, the mercury expands and covers more room in the thermometer.
What color is the Mercury in a Mercury thermometer?
Mercury in a Mercury thermometer is typically silver in color.
How mercury functions in a thermometer?
Mercury, like most substances, expands when it gets hotter and contracts when it gets colder. A mercury thermometer is designed so that the volume of the mercury can be accurately observed, as the mercury rises or falls in a marked column.
Two liquids most found in a glass thermometer?
mercury and alcohol
Can the mercury in a thermometer hurt you?
Yes, if a mercury thermometer breaks, the mercury can vaporize and be inhaled, which can be harmful to your health. It is important to handle and dispose of a broken mercury thermometer properly to avoid exposure to mercury.
What type of thermometer is widely used in science classrooms?
Frequently thermometers filled with an alcohol; but also thermometers with mercury, with thermoresistance, thermocouples, etc.
What liquid metal is most commonly used in thermometer?
The liquid metal in many thermometer is mercury (Hg).
What is Mercury thermometer use to measure?
A mercury thermometer is used to measure temperature.
Mention any two points of difference between a clinical thermometer and an ordinary mercury thermometer?
A clinical thermometer will offer more precise calibrated readings than a mercury thermometer. The range of measurable temperature differs between a clinical and a mercury thermometer with the mercury thermometer having the wider range.
What causes mercury in a thermometer to rise?
The mercury in a thermometer rises because of thermal expansion. When the temperature surrounding the thermometer increases, the molecules of the mercury expand, causing it to move up the narrow tube of the thermometer.
