Answer 2

$\tt \huge \underbrace \red{answer : } \\ \\ \sf \: let \: \: t \: \: be \: \: final \: \: temperature \: \: \\ \sf \: now \\ \sf \: m = mass = 10 \\ \sf \: s = specific \: \: heat \: \: capacity \: \\ \sf \triangle \: t = change \: \: in \: \: temperature \: \: = t - 25 \\ \sf \: we \: \: know \: \: that \\ \sf \: Q = ms \triangle \: t \\ \sf \: 50 = 10 \times 1 \times (t - 25) \\ \sf \: t = 30 \\ \sf \: so \: \: final \: \: temperature \: = 30 \degree \: {c} \\ \tt \: so \: the \: \: temperature \: \: of \: water \: \: increases \: \: by \: \: = 30 - 25 = 5 \degree \: c$
