Answer:
(a) dew condensing on a leaf
(c) ice cream melting
Explanation:
The process which can be reversed by changing the temperature , i.e. , by increasing or decreasing the temperature , is called the <u>reversible process</u> .
From the question ,
- dew condensing on a leaf is a reversible process ,
As the water on the leaf can be changed to gaseous state by increasing the temperature .
The process of condensation and evaporation are reversible of each other .
The melted ice cream can be solidified again by reducing its temperature , hence , it is a reversible process .
- an egg turning hard when boiled and the batter cooking on a hot griddle
They both are irreversible process , and by changing the temperature , we can not get back the original substance .
