Physics

1.  An insulated container contains 1.20kg of waterwith 0.73kg of ice floating in it.  You place a block ofiron with mass of 4.60kg in this ice bath.  The iron isinitially at a temperature of 400 ºC.  What is thecomposition and temperature ofthe final mixture?

For ice Lf=33.5x104J/kg.

For water c=4186J/(kg•K).

For iron c=448 J/(kg•K).

2. A heat transfer of 9.5 x 105 J is needed toconvert a block of ice at -15°C to water at 15°C.  Whatwas the mass of the block of ice?

For ice Lf=33.5x104J/kg.

For ice c=2090 J/(kg•K).

For water c=4186J/(kg•K).
