What is the halogen that forms a purple vapor when heated?
The halogen that forms a purple vapor when heated is iodine. When iodine crystals are heated, they sublimate, transitioning directly from a solid to a gas, producing a characteristic violet or purple vapor. This property is due to the molecular structure of iodine, which allows it to easily vaporize at elevated temperatures.
What element is in a violet gas form?
The element present in a violet gas form is iodine. When iodine is heated, it sublimes directly from a solid to a gas, producing a distinctive violet vapor.
What is a solid purple-black non metal which changes to a deep purple gas when heated?
Iodine is a purple-black non metal that changes to a deep purple gas when heated.
Is forms of gas when heated a physical or chemical property?
The formation of gas when a substance is heated is generally considered a physical change, as it often involves a change in state (like from liquid to gas) without altering the substance's chemical composition. However, if the heating causes a chemical reaction that produces gas (like combustion), it is a chemical change. Thus, whether it is a physical or chemical property depends on the context of the reaction.
Is there any gas that does not expand when heated?
Helium gas does not expand significantly when heated due to its low molar mass and weak intermolecular forces. This property makes helium useful in applications that require precise control of volume and pressure.
As a heated liquid turns into a gas it?
As a heated liquid turns into a gas, it ... ?
Do all gases expand equally when heated?
No, different gases have different coefficients of thermal expansion, which means they expand at different rates when heated. The expansion is determined by factors such as the molecular weight and the specific heat of the gas.
What do you call a liquid that has been heated to a gas?
A liquid that has been heated to a gas is called vapor.
Why heated gas become lighter?
because..................................................................................................................... density of heated gas is lower than cooled gas.
What does heated liquid and gas become?
A heated liquid become a gas at the boiling point.
How does that speed of the particles of a gas change when the gas is heated?
When gas is heated then its molecule get energy and start to move faster.
What is the colour of lead 2 nitrate when heated?
Lead nitrate is a white, crystalline solid. When heated, it starts decomposing with a crackling sound, producing a reddish brown gas called nitrogen dioxide, and a colourless gas, oxygen. A yellow residue of lead monoxide is left behind in the test tube.
