depending on where you live. so if you're in North Carolina it . ( temperature )
Answer:
The change in POP can not be reversed hence it is a chemical change.
Explanation:
Plaster of Paris (POP) is used to immobilize a fractured bone. The POP sets when water is added to it, it hardens irreversibly. Once it hardens, its shape can not be changed by any physical means. This means that the hardening of POP is a chemical change.
The chemical name of plaster of Paris is calcium sulfate hemihydrate. The setting of POP is an example of a chemical reaction.

Answer:
Because it helps predict the types of chemical reactions that a particular element is likely to participate in by telling each element's atomic number and usually its atomic weight
Explanation:
Explanation:
Gay-Lussac's law states that if P=pressure and T=temperature, then P/T=P/T. Temperature must be in Kelvin, but pressure can be in any unit.
To convert Celsius into Kelvin, just add 273: 10+273=283K, and 28+273=301K.
So using the equation,
200kPa÷283=? kPa÷301
Solving this equation gives you about 212.72 kPa.
