the first material thermometer by Gelileo was made up of simple apparatus, which consists of a sealed beaker in which a long tube with both open ends was connected vertically over the beaker. the top of the tube is covered with a round flask with coloured ammonia filled in the setup. when there is a difference in temperature the ammonia rises and sprays like a fountain into the round flask at the top of the setup.

Is mercury present in all types thermometers?
No, mercury is not present in all types of thermometers. While mercury thermometers are common, other types such as digital thermometers and infrared thermometers do not contain mercury. Mercury thermometers are being phased out due to environmental concerns.
What is the difference between alcohol thermometers and digital thermometers?
Alcohol thermometers use a liquid such as ethanol to measure temperature based on the expansion of the liquid, while digital thermometers use electronic sensors to detect temperature changes and provide a numerical reading. Digital thermometers tend to be more accurate and easier to read than alcohol thermometers.
What type of material was the first nuclear bomb made of?
The first nuclear bomb, known as "Little Boy," used uranium-235 as its fissile material. It was an enriched uranium bomb that was detonated over Hiroshima, Japan, in 1945.
What do they use instead of mercury thermometer?
Digital thermometers, infrared thermometers, and alcohol or galinstan thermometers are commonly used as alternatives to mercury thermometers due to the environmental and health risks associated with mercury.
What are the two substance used in liquid column thermometers?
iodine and Mercury
What where the first thermometers?
Mecury thermometers
What are modern thermometers made of?
Modern thermometers are typically made of materials such as glass, plastic, or metal. The most common type of modern thermometer is the digital thermometer, which includes a temperature sensor and a digital display screen. Other types of modern thermometers may contain mercury or alcohol as the temperature-sensitive material.
When were the first calibrated thermometers made and where?
The first calibrated thermometers were made in the early 1700s by Italian inventor Santorio Santorio, who used a sealed glass tube with a numerical scale to measure temperature. This marked the beginning of the modern temperature measurement era.
What material is used to make thermometers?
Thermometers are typically made using glass, as it is transparent and durable. Mercury or alcohol are commonly used as the liquid inside the glass tube to measure temperature. Some modern thermometers may use digital sensors and components instead of traditional materials.
When was the first accuratley calibrated thermometers made and where?
The first accurately calibrated thermometers were made in the early 18th century by Gabriel Fahrenheit in the Netherlands. Fahrenheit's mercury-in-glass thermometer established a standardized temperature scale, enabling precise measurement of temperature variations.
What material is used for thermometer?
Thermometers can be made from various materials, but common ones include glass, mercury, alcohol, and digital sensors such as thermocouples and resistive temperature detectors. Glass thermometers often contain mercury or alcohol as the temperature-measuring substance. Digital thermometers use semiconductor materials for temperature sensing.
What material was the first boat made out of?
it was made out of wood
Which material was the first roller-coaster made of?
the first roller coaster was made of wood.
Who made water thermometers?
Charles Winger invented them.
Of what type of material was the first trombone made .?
the trombone was made from wood
Which comes first the artist's imaginary or the material?
The material comes first because it is not a person who made it. The artist is only a person that uses the material for art.
How does law of expansion and contraction work in thermometers?
The material in the thermometer expands and contracts as temperature increases or reduces.
