heat problems......physics help?

Question

1.) A steel bar exactly 1 m long at 20 degrees Celcius (C) has its ends fixed in place. Obtain a crude estimate of the deflection of the center of the bar when it is heated to 200 degrees Celcius (C) by assuming that the figure formed by the hot rod is a triangle.
(if needed, the coefficent of steel is 1.2)

2.) If 6.0 kg of ice at -10 degrees C is added to 6.0 kg of water at + 10 degrees C, what is the temperature of the resulting mixture?

(if needed, specific heat capacities of water is 4.19 kJ/kg*C and ice is 2.09 kJ/kg*C)
