Is sublimation is physical change or chemical change
Answers
Answer: Sublimation is a physical change
Exxplanation:
A chemical change (reaction) is a process after which a new substance (one or more) is created. For example:
H
C
l
+
N
a
O
H
→
N
a
C
l
+
H
2
O
In this process (reaction) from 2 particles: acid (
H
C
l
) and a hydroxide (
N
a
O
H
) another 2 substances: salt (
N
a
C
l
) and water
(
H
2
O
) are formed.
In a physical change NO new substances are formed.
After sublimation a solid changes to a gas, but it is still the same substance. Only the state of matter has changed.
Hope this answer helps you a lot
