Which temperature measuring device is more accurate?

thermistors
For extreme accuracy the RTD is still the best choice, but modern thermistors are not far behind. Thermistors with 0.1 °C accuracy are now widely available and at very reasonable costs.

In what scale do we measure the actual temperature?

Celsius, also known as centigrade, is a scale to measure temperature. The unit of measurement is the degree Celsius (°C). It is one of the most commonly used temperature units in the world.

What are the methods to measure temperature?

How to Measure Temperature

• Thermocouples. Thermocouples are voltage devices that indicate temperature measurement with a change in voltage.
• Resistive Temperature Measuring Devices.
• Infrared Sensors.
• Bimetallic Devices.
• Thermometers.
• Change-of-State Sensors.
• Silicon Diode.

Is temperature a measure of kinetic energy?

Temperature is a measure of the average kinetic energy of the particles in an object. When temperature increases, the motion of these particles also increases.

How accurate is temperature measurement?

Modern high quality thermometers measure with an accuracy of +/-0.1 °C. The technical precision and clinical reliability in the use of the thermometer should not be confused. Human body temperature varies depending on where on the body the temperature is taken and the time of measurement.

What are the scales used for measuring temperature explain them?

Temperature Scales. There are three temperature scales in use today, Fahrenheit, Celsius and Kelvin. Fahrenheit temperature scale is a scale based on 32 for the freezing point of water and 212 for the boiling point of water, the interval between the two being divided into 180 parts.

Why do we measure temperature?

The measurement of body temperature can help detect illness. It can also monitor whether or not treatment is working. A high temperature is a fever.

What is temperature a measure of in chemistry?

average kinetic energy
Temperature is a measure of the average kinetic energy of the atoms or molecules in the system. The zeroth law of thermodynamics says that no heat is transferred between two objects in thermal equilibrium; therefore, they are the same temperature.

How do you measure the amount of heat in a substance?

One technique we can use to measure the amount of heat involved in a chemical or physical process is known as calorimetry. Calorimetry is used to measure amounts of heat transferred to or from a substance. To do so, the heat is exchanged with a calibrated object (calorimeter).

What is the initial temperature of a metal in boiling water?

Use this result to identify the metal. Noting that since the metal was submerged in boiling water, its initial temperature was 100.0 °C; and that for water, 60.0 mL = 60.0 g; we have:

What is the specific heat of copper in boiling water?

Noting that since the metal was submerged in boiling water, its initial temperature was 100.0 °C; and that for water, 60.0 mL = 60.0 g; we have: Comparing this with values in Table 1 in Chapter 5.1 Energy Basics, our experimental specific heat is closest to the value for copper (0.39 J/g °C), so we identify the metal as copper.

What happens to temperature when a substance dissolves?

Dissolving is usually considered a physical change but also can result in a change in temperature. This change in temperature is based on the energy changes involved in breaking and making “bonds” in the process of dissolving.
