Entropy

In physics, entropy means the amount of disorder or the degree of randomness associated with a thermodynamic system. The system is not self-organized when the entropy of the system is high. For instance, when a system is at an elevated temperature, its molecules are in random motion, vibrating and colliding with each other. During this scenario, the probability of finding a molecule at a particular place twice, is low. Under this circumstance, the system can be said to be in a high entropy.

What are "no-bake" molds, and how do they compare to green sand molds? a) "No Bake" molds replace the tradition clay-and-water or thermoset polymer binders used in traditional sand molds with resins that do not need heat in order to cure. The result is a mold that can maintain better dimensional control over high production volume. b) "No Bake" molds replace the tradition clay-and-water or thermoset polymer binders used in traditional sand molds with fine wood chips. They are then compressed with high pressure without baking. c) "No Bake" molds replace the tradition clay-and-water or thermoset polymer binders used in traditional sand molds with dry clay that do not need heat in order to cure. The result is a mold that doesn't require and baking. d) "No Bake" molds is the same as the tradition clay-and-water but used in high production volume.
