A device that measures temperature must have a temperature sensor that responds to changes in temperature, a way to convert the sensor's response into a numerical value, and a display or output to show the numerical temperature value. Additionally, the device should have the ability to calibrate and accurately measure a range of temperatures.

Can a thermometer measure its own temp?
No, a thermometer measures the temperature of its surroundings rather than its own temperature. In order to measure its own temperature accurately, a thermometer would need to maintain a separate reference temperature which is challenging to achieve in practice.
What is the use of an optical pyrometer?
A Pyrometer is a temperature measuring device. The word radiation in the name indicates that it does not have to be in contact with the object in order to measure the temprature. A Radiation Pyrometer has a sensor within which detects the Infra-Red radition [heat], sends that value to a mini-computer which converts that signal to a temperature reading. To use a Radiation Pyrometer, one simply points it at the object, pulls a trigger or presses a button, and reads a meter or display in order to determine the temperature of the object.
What is the use of a bimetallic thermometer?
A bimetallic thermometer is used to measure temperature by utilizing the difference in thermal expansion of two different metals bonded together. As temperature changes, the metals expand or contract at different rates, causing the pointer to move on the temperature scale and indicating the temperature.
What is the function of thermometer in a autoclave?
The function of a thermometer in an autoclave is to measure and display the temperature inside the autoclave chamber. This is important to ensure that the sterilization process reaches the required temperature for a specified period of time in order to effectively kill any microorganisms present on the instruments being sterilized.
A thermometer is placed in water in order to measure the water temperature. What would cause the liquid in the thermometer to drop?
If surrounding water temperature is lower than the water in the thermometer, heat will transfer from the water in the thermometer to the colder water causing the liquid in the thermometer to drop.
Why do you have to use resistors and capacitors in gadgets and devices?
Because the device needs their electrical properties in order to work.
Can a thermometer measure its own temp?
No, a thermometer measures the temperature of its surroundings rather than its own temperature. In order to measure its own temperature accurately, a thermometer would need to maintain a separate reference temperature which is challenging to achieve in practice.
What is a device that separates the light from stars and other objects according to wavelength in order to produce a spectrum?
A spectrograph is a device that separates light from stars and other objects into its different wavelengths to produce a spectrum. This allows astronomers to study the composition, temperature, and other properties of the object emitting the light through analysis of the spectrum.
Which are the sites in which a medical thermometer is inserted in order to measure body temperature?
The axilla is one of the four sites (the other three being the mouth, rectum, and ear canal) in which amedical thermometer may be inserted in order to measure body temperature.

What is an anthropometer?
An anthropometer is a device used in anthropathy - the study of the measuring of the human body in order to ascertain different dimensions at different ages - in order to measure parts of the human body.
Doug wants to find out how increasing a gas's pressure can affect the gas's temperature What tool will Doug need in order to conduct his experiment?
Doug will need a pressure gauge to measure the pressure of the gas, a temperature gauge to measure the temperature of the gas, and a container to hold the gas while adjusting the pressure.
Is there lawn care software available that will analyze both the moisture and nutrients in ground soil?
Yes, but you would require a device in order to measure both parameters. Usually, bundled with such equipment is software designed to measure and analyze such parameters.
Difference between thermistor and temperature sensor?
A thermistor is a temperature measuring device which acts like a temperature sensitive resistor. It is an active device that requires a current flow to measure its resistance so that the temperature may be calculated and/or displayed. A thermocouple is a device composed of two dissimilar metals fused together. An electrical potential occurs across the junction of the metals. As the potential is influenced by the temperature of the metal junction the output voltage can be measured and calibrated to show the temperature at the joint. Both devices may be employed to measure the temperature within a fixed space, or on a probe to measure the temperature at a remote point or points.
How does a spring balance measure the mass of an object?
A spring device can only measure an object's weight. In order to find its mass, you then have to either compare its weight with the weight of a known mass, or else use the value of gravitational acceleration to calculate the mass from the weight.
Why temperature of ice falls when sugar is added to it?
Adding sugar to ice lowers the freezing point of the ice, due to colligative properties. This means that the ice will need to absorb more heat from its surroundings in order to melt, resulting in a drop in temperature.
What instruments are the most appropriate for the meteorologist to use in order to measure temperature air pressure and wind speed?
The instruments commonly used by meteorologists to measure temperature are thermometers, for air pressure they use barometers, and for wind speed they use anemometers. These instruments provide accurate readings of these meteorological parameters in order to analyze weather patterns.
