Why do substances sublime while others do not?
Substances sublime when they transition directly from a solid to a gas phase without passing through the liquid phase due to their specific molecular structure and intermolecular forces. Substances that do not sublime might have stronger intermolecular forces that prevent the solid from breaking apart into individual molecules to form a gas phase.
Can sand sublime?
Yes. Like any solid it can sublime - but the rate of sublimation under normal conditions is so low that you would not expect to see any significant change in the mass of a grain of sand during your lifetime - or for that matter during the lifetime of the human race...
What non-water substances can evaporate?
Any liquid can be evaporated.
What is a liquid used to dissolve other substances?
Surprisingly Water is used as a solvent and is commonly considered the "Universal Solvent". This is due to it being the liquid that can dissolve the most substances out of any other liquid.
Is there any substance like water which can take the shape of liquid gas and solid?
Yes, there are some substances like carbon dioxide and ammonia that can exist as a liquid, gas, and solid at different temperatures and pressures. These substances undergo changes in state based on variations in temperature and pressure.
How does gas become a solid without going through the liquid phase?
The process is called "sublimation". When a solid melts to a liquid, it is because there is enough gas pressure to ensure that the molecules will remain grouped together, milling around each other. But if there is not enough gas pressure, the molecules will simply fly away. Any molecular solid can sublime. But ordinary pressures are enough to make sure that for most gases there will be an intermediate liquid phase. A few, though, are like carbon dioxide, and will sublime unless the molecules are forced to stay together by increasing the pressure. Others, like water, will only sublime if the pressure is reduced. Any molecular solid will sublime if the pressure is low enough.
What is the liquid that passes through a filter paper and contains any soluble substances from the orriginal mixture?
The name of this liquid is filtrate.
Is an insoluble thing always a solid?
No. An issoluble matter may remain in any state viz. solid, liquid or gaseous. The solubility is depended upon the intermolecular forces of attraction between the two substances in contact.
Where does electric current pass?
Electric current passes through substances called "conductors", as well as "semiconductors". Conductors include all metals, and any liquid with ions in it.Electric current passes through substances called "conductors", as well as "semiconductors".

Is Sublime of a solid to gas chemical or physical change?
Change of state is always physical. You have not lost or gained any atoms. Therefore its physical.
What is Substances that assume the shape of their container but do not have the definite size are called?
Substances that assume the shape of their container but do not have a definite size is water or any liquid substance.
What is definition of liquid waste?
Liquid waste refers to any waste material that is in a liquid state, such as wastewater from households, industries, or agriculture. It can contain pollutants, chemicals, or other harmful substances that can have detrimental effects on the environment if not properly managed and treated. Liquid waste is usually regulated by environmental protection agencies to ensure proper disposal and treatment.
