# Three beakers labeled as A, B and C each containing 25 mL of water were taken. A small amount of NaOH, anhydrous CuSO4 and NaCl were added to the beakers A, B and C respectively. It was observed that there was an increase in the temperature of the solutions contained in beakers A and B, whereas, in the case of beaker C, the temperature of the solution falls. Which one of the following statement(s) is (are) correct?- In beakers A and B, the exothermic process has occurred.
- In beakers A and B, the endothermic process has occurred.
- In beaker C exothermic process has occurred.
- In beaker C endothermic process has occurred.

**(a) (i) only**

**(b) (ii) only**

**(c) (i) and (iv)**

**(d) (ii) and (iii)**

Correct Answer: (c) (i) and (iv)

Explanation: Exothermic processes will increase the temperature whereas endothermic processes will decrease the temperature.
