Question

The value of specific heat for copper is 390 J/kg⋅C∘, for
aluminun is 900 J/kg⋅C∘,and for water is 4186 J/kg⋅C∘.

What will be the equilibrium temperature when a 275 g block of
copper at 255 ∘C is placed in a 155 g aluminum calorimeter cup
containing 815 g of water at 16.0 ∘C?

Answer #1

using equation

m_{f} C_{f}
T_{f} =
m_{i} C_{i} T_{i} where i = 1 , 2 ,
3............

( 0.275 X 390 + 0.155 X 900 + 0.815 X 4186 ) T_{f} = (
0.275 X 390 X 255 + 0.155 X 900 X 16 + 0.815 X 4186 X 16 )

T_{f} = ( 0.275 X 390 X 255 + 0.155 X 900 X 16 + 0.815 X
4186 X 16 ) / ( 0.275 X 390 + 0.155 X 900 + 0.815 X 4186 )

T_{f} = ( 0.275 X 390 X 255 + 0.155 X 900 X 16 + 0.815 X
4186 X 16 ) / ( 0.275 X 390 + 0.155 X 900 + 0.815 X 4186 )

**T _{f} =
23.0066^{o}C**

**the equilibrium temperature is T _{f} =
23.0066^{o}C**

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

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)

A cube of ice is taken from the freezer at -5.5 ∘C and placed in
a 85-g aluminum calorimeter filled with 300 g of water at room
temperature of 20.0 ∘C. The final situation is observed to be all
water at 16.0 ∘C. The specific heat of ice is 2100 J/kg⋅C∘, the
specific heat of aluminum is 900 J/kg⋅C∘, the specific heat of
water is is 4186 J/kg⋅C∘, the heat of fusion of water is 333 kJ/Kg.
