A hot 119.8g lump of an unknown substance initially at 166.6 C is placed in 35.0 mL of water initially at 25.0 C and the system is allowed to reach thermal equilibrium. The final temperature of the system is 84.9 C.

Using this information and the specific heat values for several metals in the table, identify the unknown substance. Assume no heat is lost to the surroundings.

Substance	Specific Heat
aluminum	0.897
graphite	0.709
rhodium	0.243
titanium	0.523
tungsten	0.132
zinc	0.388
water	4.184

I answered rhodium, as I got -0.2142 and took the absolute value. Then I answered tungsten thinking we would be looking at the lowest number.
