What yellow solid heated in no air turns black?
Sulfur is a yellow solid that, when heated in the absence of air, sublimes into a black solid as it undergoes a phase change from solid to gas.
Which nonradioactive halogen occurs as a solid?
Iodine is a nonradioactive halogen that occurs as a solid at room temperature and pressure.
What is sublimation and give an example of a substance that sublimes?
If zinc chloride is heated strongly the solid will sublime.
Is comphor a solid liquid or gas?
It is very interesting to know that camphor is solid at room temperature. However if it is heated even slightly, it changes into gaseous state.
Which of the elements with four letters is not solid at room temperature?
One element with four letters that is not solid at room temperature is iodine. It is a purple-black solid that sublimes into a purple gas at room temperature.
Which of the element is sublimes on heating?
One example of an element that sublimes on heating is iodine. When solid iodine is heated, it directly changes into a gas without passing through a liquid phase.
What element sublimes when gently heated?
Iodine is an element that sublimes when gently heated. Sublimation is the process of a substance transitioning directly from a solid to a gas phase without passing through the liquid phase.
What is an element that is a shiny black solid and gives off a purple vapor when heated?
Iodine ------------------------------------------- The element you describe sounds like iodine, a good test to make sure that it is iodine is to see if the substance sublimes. This means a solid sample of iodine will turn straight from a solid into a gas with no liquid stage.
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 yellow solid heated in no air turns black?
Sulfur is a yellow solid that, when heated in the absence of air, sublimes into a black solid as it undergoes a phase change from solid to gas.
What kind of solid is iodine?
Iodine is a chemical element, nonmeatal, halogenÈ™ it is solid at room temperature but can sublime easily.
If ammonium chloride and sand under goes sublimationwhich solid sublimes?
Ammonium chloride sublimes when heated, transitioning from a solid directly to a gas without passing through a liquid phase. Sand does not undergo sublimation as it does not turn into a gas when heated, but rather melts at high temperatures.
What ductility of iodine?
Iodine is a brittle solid at room temperature and does not exhibit ductility. It easily sublimes into a gas when heated.
What black solid forms a purple vapour when heated gently?
Iodine is a black solid that sublimes directly to a purple vapor without passing through a liquid phase when heated gently.
Which nonradioactive halogen occurs as a solid?
Iodine is a nonradioactive halogen that occurs as a solid at room temperature and pressure.
What state is the iodine in when it is heated?
When iodine is heated, it sublimes from a solid state directly into a purple-colored gas. It undergoes sublimation, which means it changes from a solid to a gas without passing through the liquid state.
What is sublimation and give an example of a substance that sublimes?
If zinc chloride is heated strongly the solid will sublime.
