Question

Is burning the glass plate is physical or chemical change?

Answer 1

This is a chemical reaction because stour adding heat, you are chemically doing something, physical is when you point out the obvious using your five senses. Touching it to feel how soft on object is, or what colour (vision). You are adding heat which is chemical.

Answer 2

This is a physical change because you are burning the glass plate and that changes the plate. I hope this helps. HAVE A GREAT DAY
