Before thermometers use to have Mercury in them and they are not harmful unless they are used properly. Mercury is harmful when it is not disposed of properly and if it spills. It is not used very much because it poses a threat to human health and the environment. Now most thermometers have alcohol in them, they work just as well as mercury thermometers but are more safe to use in case the thermometer breaks.

What were the changes that Edward Cullen went through during Breaking Dawn?
The most major change he went through was becoming a father.
How does a temomether work?
A thermometer works by measuring temperature through a physical property that changes with temperature, such as the expansion of a liquid (mercury or alcohol) or a metal coil. When the temperature changes, the property changes, leading to a corresponding movement of the indicator on the thermometer scale. This allows us to read and interpret the temperature accurately.
What is a laboratory thermometer?
A laboratory thermometer is used to check the temperature, or changes in temperature, of an object with precise accuracy.
Constant volume thermometer?
A constant volume thermometer measures temperature by keeping the volume of the gas inside the thermometer constant. As temperature changes, the pressure of the gas inside the thermometer also changes, which can be correlated to the temperature. This type of thermometer is commonly used in laboratories and for precision measurements.
Is there any thermometer which changes its colour due to temperature change?
Yes,its called as "liquid crystal thermometer".
What is meant by sensitivity of thermometer?
The sensitivity of a thermometer refers to how quickly and accurately it responds to changes in temperature. A high sensitivity thermometer will provide a quick and precise reading with even slight variations in temperature, while a low sensitivity thermometer may be slower to reflect changes in temperature.
What is meant by responsiveness in thermometer?
Responsiveness in a thermometer refers to how quickly and accurately the thermometer reflects changes in temperature. A responsive thermometer will quickly show fluctuations in temperature without lagging behind the actual temperature changes. This is important for obtaining accurate and real-time temperature readings.
How does an electrical thermometer works?
An electrical thermometer works by measuring changes in electrical resistance as temperature changes. This change in resistance is then converted into a temperature reading. The resistance of the sensor in the thermometer varies with temperature, allowing for accurate temperature measurements.
How do you calculate the sensitivity if the thermometer?
Sensitivity of a thermometer is calculated by dividing the change in temperature measured by the thermometer by the change in the actual temperature. This gives a measure of how accurately the thermometer can detect small changes in temperature.
What is measuring lag of thermometer?
When the temperature changes, how long it takes for the thermometer to catch up and show the correct value.
What is a glass bulb of a thermometer?
A glass bulb of a thermometer is the part at the bottom of the thermometer that contains mercury or colored alcohol that expands and contracts with temperature changes. This expansion and contraction of the liquid is what causes the thermometer to measure and display the temperature.
What change takes place in the liquid inside a thermometer when it is placed into somthing cold?
The liquid inside the thermometer "contracts" when it is placed into something cold. This means that it decreases in volume and increases in density. This is the reason that the thermometer can measure heat: the volume of the liquid inside the thermometer changes as a function of heat, and the amount of liquid in the "tube" of the thermometer changes as a function of volume. Because of this relationship, the level of the liquid in the tube of the thermometer changes as a function of heat.
