In the lab, you have nails with mass Mn and temperature Tn.
You submerge those nails in the water with mass Mw and temperature Tw.
Specific heat capacities of nails Cn and water Cw are
Cn = 0.12 cal/gC
Cw = 1.00 cal/gC
Presume no energy loss (all energy transfer is only between water and nails).
Find the resulting temperature of nails in the water after temperature is equalized given the following values:
Mn = 139 g
Tn = 119 C
Mw = 119 g
Tw = 27 C
Enter 2 digits after decimal point.
