Is sublime a physical change or chemical change?
Sublime is a physical change because it involves a substance changing from a solid directly to a gas without going through a liquid phase. This process is reversible, and the chemical composition of the substance remains the same.
Is carbon dioxide a sublime substance?
No, carbon dioxide is a gaseous substance at room temperature and pressure. Sublimation is the process where a substance transitions directly from a solid to a gas without passing through the liquid phase. CO2 can also undergo sublimation under certain conditions.
How do you change a substance change of matter?
By heating or freezing.
How do you change a substance state of matter?
By heating or freezing.
What is the relationship between energy transfer and temperature change?
Energy transfer and temperature change are directly related. When energy is transferred to a substance, such as through heating, the temperature of the substance increases. The amount of temperature change depends on the amount of energy transferred and the specific heat capacity of the substance.
What example of changing a substance is an example of what?
iodine'(solid) can sublime to gas. also so does camphor Sublimation is a physical change, not a chemical change. Any substance that burns demonstrates a chemical change called combustion.
The expansion of matter upon heating is an example of what change?
The expansion of matter upon heating is an example of a physical change. This is because the substance undergoes a change in form or appearance without forming a new substance.
What is needed fora solid to sublime and what change of state occurs?
For a solid to sublime, it needs to undergo a change in temperature and pressure that allows it to transition directly from a solid to a gas without passing through the liquid state. This change of state is called sublimation.
Is heating a chemical or physical change?
Heating a substance can result in either a physical change or a chemical change. A physical change does not alter the substance's composition, such as melting or boiling, while a chemical change leads to the formation of new substances with different properties, such as burning or baking.
Is there a substance that can change directly from a gas to a solid?
KAPOOR
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 is the common property of iodine and naphthalene?
they both sublime, in which the solid particles will change directly into gas.
