1.An electric heater with a power ratinl*xcie+ ;m:l zr w,lk-g oh02vmh0e )h5 dx+7 r f;kz7evco:mvaf f 2.8 kW heats liquid that flows through it. The temperature of the liquid i7kevv0: x)+h5m rf faehv 02moc;hz7dncreases from $18^{\circ}C$ to $38^{\circ}C$while passing through the heater. The flow rate of the liquid σ is $0.035\,kgs^{−1}$. Calculate the specific heat capacity of the liquid. c =    $J\,kg^{-1}\,K^{-1}$
2.Suggest whether your answer for (a) is above or below the actual value of the specific heat capacity. Justify your answer.
