The initial temperature of the water and the beaker is Tw,b = 12.0°C. 1.) A copper sample (ccu = 387 J/kg K) of mass me = 75 g and temperature Te 312°C is dropped into a glass beaker that contains a mass of water mw = 220 g (Cw= 4190 J/kg K). What is the final temperature of the copper, beaker, and water? The heat capacity (the specific heat times the mass) of the beaker is Cb'= 190 J/K.

Transcribed Image Text:4. Why do coastal regions tend to have a more moderate climate than inland regions?
Problems (Part 3)
The initial temperature of the water and the
beaker is Tw,b = 12.0°C.
A copper sample (cCu 387 J/kg•K) of mass me
= 75 g and temperature Te 312°C is dropped
into a glass beaker that contains a mass of
water mw = 220 g (Cw= 4190 J/kg K).
What is the final temperature of the copper,
beaker, and water?
The heat capacity (the specific heat times the
mass) of the beaker is Cb' = 190 J/K.
2. What mass of steam at 100°C must be mixed
with 150 g of ice at -10°C, in a thermally
insulated container, to produce liquid water at
50°C?
Data: Ly = 2256 kJ/kg
Lf = 333 kJ/kg
Cw = 4190 J/kg K
Cice = 2220 J/kg K *
