Question

. All final answers must have the correct number of significant figures All final answers must include the correct units and direction (where appropriate) .

Answer 1

Solution: Given:- Mass,m = 0.755 kg, Initial temperature, T₁ = 19.4^oC = 292.4K, Heat, Q = 94.3 kJ.

Let T₂ be the final temperature.

Heat transfer is given by,

$Q=m\times C_{p}\times \Delta T$

Here, C_p is specific heat 1kJ/Kg.K

and C_p=1kJ/Kg.K

$94.3=0.755\times1\times (T_{2}-292.4)$

. Ans

T2 144.3°C
