(a)
Interpretation:
The explosion of a firecracker is a chemical change or not is to be stated with appropriate evidence.
Concept introduction:
A chemical change takes place when a new substance is produced through a
(b)
Interpretation:
The evaporation of a puddle of water is a chemical change or not is to be stated with appropriate evidence.
Concept introduction:
A chemical change takes place when a new substance is produced through a chemical reaction. The physical change occurs when a matter changes its form but not its chemical identity.
(c)
Interpretation:
The burning of a candle is a chemical change or not is to be stated with appropriate evidence.
Concept introduction:
A chemical change takes place when a new substance is produced through a chemical reaction. The physical change occurs when a matter changes its form but not its chemical identity.
(d)
Interpretation:
The process of dispersion through a prism is a chemical change or not is to be stated with appropriate evidence.
