Respuesta :
The final temperature of the system has been 130[tex]\rm ^\circ C[/tex].
Specific heat can be defined as the amount of heat required to raise the temperature of 1 g of substance by 1-degree celsius.
The amount of heat lost and the heat gained have been equal.
Heat = mass × specific heat × change in temperature
Thus,
mc[tex]\Delta[/tex]T = mc[tex]\Delta[/tex]T
50 g × (10 - x) = 120 × (x - 80)
500 - 50x = 120x - 9600
70x = 9100
x = 130
Thus, the final temperature of the system has been 130[tex]\rm ^\circ C[/tex].
