The value for the activation energy in the temperature region.
Answer to Problem 101AAP
The value for the activation energy in the temperature region is
Explanation of Solution
Write the equation involving the viscosity to temperature for a viscous flow in the glass.
Here, viscosity of the glass is
For the strain point, write the equation involving the viscosity to temperature for a viscous flow in the glass.
Here, viscosity of the glass at strain point is
For the softening point, write the equation involving the viscosity to temperature for a viscous flow in the glass.
Here, viscosity of the glass at softening point is
Conclusion:
Convert the unit of strain point temperature to absolute value.
Convert the unit of softening point temperature to absolute value.
Divide Equation (II) by Equation (III).
Substitute
Thus, the value for the activation energy in the temperature region is
