Metal has a high co-efficient of expansion and would show the wrong temperature by expanding to give more volume in relation to glass on heating and opposite effect when cooling

What materials are used in the construction of a light bulb?

A light bulb is typically made of a glass bulb, a tungsten filament, and a metal base. The glass bulb encloses the filament and is filled with an inert gas like argon or nitrogen. The filament is made of tungsten, a metal known for its high melting point and durability. The metal base is used to connect the bulb to an electrical circuit.


What is the function of the metal casing and tip of the bulb?

The metal casing of a light bulb serves as a protective barrier, preventing the bulb from breaking easily and protecting the delicate inner components from damage. The metal tip is where the electrical contact is made to supply power to the bulb, allowing the electricity to flow through the filament or LED inside the bulb, which then produces light.


What is the differences between a clinical thermometer and a laboratory thermometer?

Clinical thermometers are made to be used in a hospital to accurately determine body temperature. They are often digital. Lab thermometers are made of metal or glass and usually don't give you an accurate reading as much as a "ball park." A clinical thermometer may have mercury but lab thermometers usually have alcohol .


What metal is a light bulb filament made of?

A light bulb filament is typically made of tungsten metal. Tungsten is chosen for its high melting point and good electrical conductivity, making it ideal for producing light through resistive heating when an electric current passes through it.


What state of matter is a light bulb?

A light bulb is typically a solid state of matter, as it is made of materials like glass, metal, and plastic. Inside the bulb, the filament is in a gaseous state when the bulb is switched on, but the overall state of the bulb itself remains solid.

Where is the metal tip on the light bulb?

The metal tip of a light bulb is located at the base where the bulb connects to the socket. It is usually made of brass or another conductive material to allow electricity to flow into the bulb.


What are thermometers made of today?

Thermometers today are typically made of glass, plastic, or metal. They contain a temperature-sensitive element, such as mercury or alcohol, that expands or contracts with temperature changes, causing the level to rise or fall in the measuring column. Digital thermometers are also common, using electronic sensors to measure temperature.

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.

What is the metal thing on the light bulb called?

The metal thing in the bulb that shines really has no definition. It is only a part of the mechanism. The "metal thing" is called the filament and they are usually made of tungsten, which is the metal with the highest melting point. Higher than steel, but not stronger than steel.


What element are light bulb filaments made out of?

Tungsten, a metal with a very high melting-point.
