Is liquid to gas chemical change?
No, the change from liquid to gas is a physical change, not a chemical change. In this process, the substance's molecular structure remains the same, only its physical state changes from liquid to gas.
Is changing of a solid to liquid chemical or physical change?
No it is a chemical
Is pouring liquid a chemical change or physical?
A physical change.
When a substance changes from one state to another do the chemical properties change?
From solid to liquid, from liquid to gaseous, from gaseous to liquid, from liquid to solid, and in sublimation from solid to gaseous or the reverse, chemical properties do not change.
Is melting iron into liquid a chemical change?
Yes, melting iron into a liquid state is a physical change, not a chemical change. This process involves applying heat to change the state of the iron from solid to liquid, without altering its chemical composition.
What is the mercury called on a clinical thermometer?
The liquid in a clinical thermometer is called mercury. It is used to measure body temperature by expanding and rising within the thermometer.
Is it a physical or chemical change when the liquid mercury in a thermometer expands as it is heated?
physical change
What are the characteristics of the liquid used in a liquid in a glass thermometer?
The liquid in a glass thermometer is typically a non-toxic and non-reactive liquid such as mercury or colored alcohol. These liquids have a high coefficient of thermal expansion, allowing them to accurately measure temperature changes by expanding or contracting within the narrow capillary tube of the thermometer.
What is the liquid mercury in a thermometer expands as its heated what is this a?
physical change
Is there any thermometer which changes its colour due to temperature change?
Yes,its called as "liquid crystal thermometer".
What are examples of thermal expansion of a liquid?
Examples of thermal expansion of a liquid include water expanding as it is heated, causing liquids like mercury in a thermometer to rise when exposed to heat, and gasoline expanding in a fuel tank on a hot day.
How does a glass thermometer works?
As the liquid in the thermometer is heated it expands, and the only way the expanding liquid can go is upward. As the liquid in the thermometer cools, it will contract, and the liquid will fall back down into the resevoir, causing the column of liquid to move downward.
How does temperature affect s thermometer?
Temperature affects a thermometer by causing the liquid or material inside to expand or contract, leading to a change in volume. This change in volume is measured by the scale on the thermometer, so as temperature increases or decreases, the level of the liquid or material inside the thermometer will rise or fall accordingly.
How the liquid in a thermometer change so that it can be used to measure a temperature?
The liquid in a thermometer expands and contracts as the temperature changes. This causes the liquid to rise or fall in a narrow tube connected to the bulb of the thermometer. The markings on the tube indicate the temperature based on how high or low the liquid level is.
What change takes place in the liquid inside a thermometer when it is placed into somthing cold?
The liquid inside the thermometer "contracts" when it is placed into something cold. This means that it decreases in volume and increases in density. This is the reason that the thermometer can measure heat: the volume of the liquid inside the thermometer changes as a function of heat, and the amount of liquid in the "tube" of the thermometer changes as a function of volume. Because of this relationship, the level of the liquid in the tube of the thermometer changes as a function of heat.
How can a thermometer be used to help you decide whether your observation is physical or chemical change?
A thermometer can help you decide whether your observation is a physical or chemical change by measuring the temperature change. A physical change typically involves a change in state (solid, liquid, gas) without changing the chemical composition, so the temperature may remain constant. In contrast, a chemical change usually involves the breaking and forming of chemical bonds, which can result in a temperature change.
What liquid used in traditional thermometer is now considerddangerous to general use?
The liquid is mercury; it has now been replaced with a cheaper and safer chemical.
