What are the 3 parts of digital thermometer?
A simple digital thermometer consists of a thermocouple, a battery- powered, dual-slope digital voltmeter, and an electronic display.
What are the 3 units of thermometer?
The temperature can be measured in Celsius, Fahrenheit, and kelvin. The metric system has two scales: the Celsius scale and the metric system.
What makes a thermometer work?
The material conducts heat energy to the mercury when it is touched by the mercury thermometer. As mercury becomes a liquid, it starts to rise up the tube. The reading of the temperature can be taken at the place where the mercury stops.
What are the 4 lines on a thermometer?
The temperature can be measured on two scales, Fahrenheit and Celsius. You can find the numbers for F by looking at them. The temperature is determined by the length of the line. Two tenths of a degree of temperature can be reached by the four short lines between the long lines.
What are the thermometer scales called?
Many temperature scales are used. Scales have been used throughout history.
What are the three main features of a clinical thermometer?
A glass tube with a bulb at one end is used to measure the temperature of the instrument. This bulb and a portion of the glass tube are filled with liquid that can be alcohol or mercury. There is a vacuum in the rest of the tube.
What is the construction of a simple thermometer?
The bulb is filled with mercury. The bulb has a capillary tube attached to it. The tube is narrow above the bulb.

What is the stem of a thermometer called?
The stem or capillary tube is a sealed glass tube that contains a glass bulb.
What are the sides of a thermometer?
