Answer 1

Answer:

Bursting of crackers, melting of ice-Specify the heat process involved in them

Answer 2

The heat processes involved in the following are as follows:

1. Bursting of crackers- Combustion reaction

• In the bursting of crackers, when the gunpowder in it comes in contact with the oxygen in the air, it combusts, and an explosion takes place.
• In this chemical change, heat and light are released.

2. Melting of ice- Endothermic process.

• The melting of ice is called an endothermic process as it absorbs heat to change its state.
• In this physical change, heat is absorbed to break the ice bonds and turn them into water.
