Five thermal energy transfers that occur.

(a)

Expert Solution

Explanation of Solution

Aluminum container at 20°C contains ethyl alcohol at 30°C and ice at 0°C . Heat transfer from hot to cold body occurs. The mixture and the container attains an equilibrium temperature.

Ice at −10°C increases in temperature and becomes Ice at 0°C , then phase change occurs from ice to cold water at 0°C , then the temperature of the cold water at 0°C raises to a value T. Temperature of the Aluminum container at 20°C raises to a value T and ethyl alcohol at 30°C temperature rises to a value. The mixture and the container attain an equilibrium temperature T.

(c)

Expert Solution

Explanation of Solution

According to the conservation of energy, heat lost by one in a mixture is equal to heat gained by the other.

Summing up all the energy expressions and equating it to zero.

{micecice[0−(−10.0°C)]+miceLf+micecwater[Tf−0]+mAlcAl[Tf−20.0°C]+mEAlccEAlc[Tf−30.0°C]=0}

Conclusion:

The equation denoting the conservation of energy after summing up all the expression and setting it to zero is constructed.

Expert Solution

Answer to Problem 34P

The final equilibrium temperature is T=4.81°C

Explanation of Solution

Given Info: Mass of aluminum container is 0.500 kg, initial temperature of the aluminum container is 20.0°C , mass of ethyl alcohol is 6.00 kg, initial temperature of ethyl alcohol is 30.0°C , mass of ice is 100 kg, initial temperature of ice is −10.0°C .

Formula to calculate the heat gained by cold water is,

{micecice[0−(−10.0°C)]+miceLf+micecwater[Tf−0]+mAlcAl[Tf−20.0°C]+mEAlccEAlc[Tf−30.0°C]=0}

Rearrange in terms of Tf .

{micecice(10.0°C)+miceLf+micecwaterTf+mAlcAlTf−mAlcAl(20.0°C)+mEAlccEAlcTf−mEAlccEAlc(30.0°C)}=0micecwaterTf+mAlcAlTf+mEAlccEAlcTf={−micecice(10.0°C)−miceLf+mAlcAl(20.0°C)+mEAlccEAlc(30.0°C)}Tf={−mice[cice(10.0°C)+Lf]+mAlcAl(20.0°C)+mEAlccEAlc(30.0°C)}micecwater+mAlcAl+mEAlccEAlc

Substitute all quantities in the second through sixth columns into the last column and sum to find T.

Tf={−(1.00 kg)[(2090 J/kg°C)(10.0°C)+(3.33×105 J/kg)]+[(0.500 kg)(900 J/kg°C)(20.0°C)]+[(6.00 kg)(2430 J/kg°C)(30.0°C)]}((1.00 kg)(4186 J/kg°C)+(0.500 kg)(900 J/kg°C)+[(6.0 kg)(2430 J/kg°C)])=9250019216=4.81°C

Conclusion:

Therefore, the final equilibrium temperature is 4.81°C .
