The aluminum

The aluminum object with a weight of 0.80 kg and a temperature of 250°C was placed in the water with a weight of 1.6 kg and a temperature of 23°C. What is the system temperature after reaching equilibrium? We assume that the heat exchange occurred only between the aluminum object and the water. The mass heat capacity of aluminum is 900 J/kg∙°C.

Correct answer:

t =  44.9677 °C

Step-by-step explanation:

m1=0.80 kg t1=250c1=900 J/kg/ m2=1.6 kg t2=23c2=4200 J/kg/ Q1=Q2    m1 c1 (t1t)=m2 c2 (tt2) 0.8 900 (250t)=1.6 4200 (t23)  7440t=334560  t=13943144.967742=44.9677C
