A student doing an experiment pours 0.500 kg of heated metal
whose temperature is 98.0 oC into a 0.356 kg aluminum
calorimeter cup containing 0.418 kg of water at 28.0 °C. The
mixture (and the cup) comes to thermal equilibrium at 38.0 °C. The
specific heat of the metal is ________ J/kg oC.
(specific heat of aluminum = 900 J/kg oC, specific heat
of water = 4186 J/kg oC)

In an experiment, 100 g of aluminum (with a specific heat of 900
J/kg·K) at 79.0°C is mixed with 80.0 g of water (with a specific
heat of 4186 J/kg·K) at 43.0°C, with the mixture thermally
isolated. (a) What is the equilibrium temperature?
What are the entropy changes of (b) the aluminum,
(c) the water, and (d) the
aluminum-water system?

In an experiment, 150 g of aluminum (with a specific heat of 900
J/kg·K) at 67.0°C is mixed with 69.0 g of water (with a specific
heat of 4186 J/kg·K) at 18.0°C, with the mixture thermally
isolated. (a) What is the equilibrium temperature? What are the
entropy changes of (b) the aluminum, (c) the water, and (d) the
aluminum-water system?

When a 270-gg piece of iron at 180 ∘C∘C is placed in a 95-gg
aluminum calorimeter cup containing 250 gg of liquid at 10∘C∘C, the
final temperature is observed to be 34 ∘C∘C. The value of specific
heat for iron is 450 J/kg⋅C∘J/kg⋅C∘, and for aluminum is 900
J/kg⋅C∘J/kg⋅C∘.
Determine the specific heat of the liquid.
