1 a. How much does the student weigh (in newtons)? Remember, w = m-g
and g = 10 m/s^2. *

A175 g lump of molten lead at its melting point (327 c) is placed into 55.0 g of water at 20.0 c. the specific heat of lead is 130.j/kg c and the hf of lead is 20,400 j/kg. when the lead and the water have reached equilibrium, what is the temperature of the mixture?

Zeros that follow non-zeros numbers and are also to the right of a decimal point are significant
