Answer:
Chemical change
Step-by-step explanation:
A change in colour indicates that a new substance with different properties (colour) has been formed. This is a chemical change.
A. is <em>wrong</em>. A physical change does not usually cause a change in colour.
B. is <em>wrong</em>. No new gas or solid was formed,
C. is <em>wrong</em>. There is a colour change, not a temperature change.
The main reason behind this is Boyle's law and Gay Lussacs law
- Gay Lussac's law states that Pressure is directly proportional to Temperature.
- Boyle's law states that Volume is inversely proportional to pressure.
If temperature will be more Pressure will be more
