What is red substance in thermometer?
The red substance in a thermometer is typically mercury. Mercury is used in thermometers because it expands and contracts uniformly with changes in temperature, making it an effective liquid for measuring temperature accurately.
Is liquid nitrogen a pure substance or a mixture?
Liquid nitrogen is a pure substance because it consists of only nitrogen molecules in liquid form.
Why does the substance in the thermometer go up when it gets hot?
The substance inside a thermometer expands when it gets hot due to increased kinetic energy of its molecules. This expansion causes the liquid to rise up the column, indicating a higher temperature reading.
What liquid expands instead of contracts when frozen?
Water is a liquid that expands when it freezes. This is due to the unique structure of water molecules, causing them to form a crystalline lattice when frozen, which takes up more space than liquid water.
What is a non-liquid substance?
A non-liquid substance is a material that is not in a liquid state, such as a solid or a gas.
Is grass a solid?
What the hell are you talking about? Of course grass is a solid. Is it a liquid? Is it a gas? Is it a plasma?Jesus christ.
What is so unusual about water when it goes from a liquid to a solid?
It expands. Most substances contract on freezing.
What is red substance in thermometer?
The red substance in a thermometer is typically mercury. Mercury is used in thermometers because it expands and contracts uniformly with changes in temperature, making it an effective liquid for measuring temperature accurately.
Compared to most substances water is unusual because when it goes from a liquid to a solid state it?
expands instead of contracts. This is due to water molecules forming a crystalline structure when freezing, creating a network that takes up more space than its liquid form. This unique behavior is why ice floats on water.
Why mercury used as thermotric liquid?
because it expands when it is hot
Why does the liquid in the thermometer go up and down when the weather changes?
The liquid in the thermometer expands or contracts based on temperature changes. When the weather is warmer, the liquid expands and rises up the tube, and when it's cooler, the liquid contracts and goes down. This movement indicates the temperature changes on the thermometer scale.
Why does water expand when cold?
Water expands when it freezes because the molecules arrange themselves in a hexagonal structure, with more space between them compared to the liquid state. This increased space results in the expansion of the substance, causing ice to be less dense than liquid water.
Is liquid nitrogen a pure substance or a mixture?
Liquid nitrogen is a pure substance because it consists of only nitrogen molecules in liquid form.
Do liquids expands when heated?
Only one liquid expands when heated and thats water the most common liquid.
When a liquid changes phase does it become a new substance?
no because it cannot be change because its water liquid
Is oil a compressible liquid?
No, because it is not compund substance
Why is liquid used in thermometer?
Liquid is used in a thermometer because it expands and contracts uniformly with changes in temperature, allowing for accurate temperature measurements. The liquid inside the thermometer expands and rises in the capillary tube as it gets warmer, providing a visible indication of temperature.
