Hello⏹️✌️
when some zinc granules are placed in copper sulphate solution the solution change its colour., since zinc is more reactive than copper, zinc reacts with copper sulphate (blue) and forms zinc sulphate and copper forms the precipitate..
CUSO4 + ZN = ZNSO4 + CU

The correct option is 2
Explanation:
The reaction between zinc and copper sulphate is an exothermic reaction which means that heat is released with the formation of products.
This released heat help in increasing temperature of the system.
