When 600 mL of 0.2 M HNO3HNO_3HNO3​ is mixed with 400 mL400 \mathrm{~mL}400 mL of 0.1 M NaOHNaOHNaOH solution in a flask, the rise in temperature of the flask is ‾\underline{\hspace{2cm}}​×10−2 ∘C\times 10^{-2}{ }\,^{\circ} \mathrm{C}×10−2∘C. (Enthalpy of neutralisation =57 kJ mol−1=57 \mathrm{~kJ} \mathrm{~mol}^{-1}=57 kJ mol−1 and Specific heat of water =4.2 JK−1 g−1=4.2 \,\mathrm{JK}^{-1} \mathrm{~g}^{-1}=4.2JK−1 g−1) (Neglect heat capacity of flask)
