<span>I think this is due to aerodynamics. Air is the stuff this is all around you. carry your hand in front of your physique which includes your palm dealing with sideways so as that your thumb is on appropriate and your pinkie is dealing with the floor. Swing your hand back and forth.</span>
        
             
        
        
        
Data:
Q = 402.7 J → releases → Q = - 402.7 J
m = 16.25 g
T initial = 54 ºC
adopting: c = 4.184J/g/°C
ΔT (T final - T initial) = ?
Solving:
Q = m*c*ΔT
-402.7 = 16.25*4.184*ΔT
-402.7 = 67.99*ΔT


If: ΔT (T final - T initial) = ?
