The Mercury thermometer revolutionized temperature measurement by providing a more accurate and consistent method compared to previous instruments. This led to advancements in various fields such as medicine, meteorology, and scientific research, improving our understanding of temperature and its effects on the world. However, the use of mercury has environmental and health concerns, leading to the development of alternative thermometers.
What else can I help you with?
What color is the Mercury in a Mercury thermometer?
Mercury in a Mercury thermometer is typically silver in color.
What makes mercury in a thermometer go up and down?
Change in temperature is what cause the Mercury to expand up (hotter) or shrink down (colder).
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 is constant in mercury- in- glass thermometer?
One constant in a mercury-in-glass thermometer is the volume of mercury in the bulb, which expands and contracts with temperature changes. Another constant is the linear expansion coefficient of the glass tube, which allows for an accurate measurement of temperature based on the change in volume of the mercury.
How does Mercury within a thermometer change?
The temperature in a Mercury-based thermometer is read by the level of Mercury found in the thermometer. As Mercury heats up, it expands, therefore raising the level of the Mercury of which we see as a higher temperature. On the other end, as the temperature falls, the Mercury contracts and reads at a lower temperature.
Is mercury expanding in a thermometer a chemical or physical change?
Physical. The mercury doesn't change.
What is the liquid mercury in a thermometer expands as its heated what is this a?
physical change
What color is the Mercury in a Mercury thermometer?
Mercury in a Mercury thermometer is typically silver in color.
Is alcohol expanding in thermometer on a hot day a physical or a chemical change?
1 physical 2 ITS MERCURY THAT IS IN A THERMOMETER
What makes mercury in a thermometer go up and down?
Change in temperature is what cause the Mercury to expand up (hotter) or shrink down (colder).
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 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 is constant in mercury- in- glass thermometer?
One constant in a mercury-in-glass thermometer is the volume of mercury in the bulb, which expands and contracts with temperature changes. Another constant is the linear expansion coefficient of the glass tube, which allows for an accurate measurement of temperature based on the change in volume of the mercury.

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.
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.
