What are the benefits and drawbacks to having a pouring temperature that is much higher than the metal’s melting temperature?
Mashcka [7]

Answer:

The main advantage would be that with the pouring temperature being much higher, there is very little chance that the metal will solidify in the mould while busy pouring. This will allow for moulds that are quite intricate to still be fully filled. The drawbacks, though, include an increased chance defects forming which relates to shrinkage (cold shots, shrinkage pores, etc). Another drawback includes entrained air being present, due to the viscosity of the metal being low because of the high pouring temperature.

Which statement best describes what happens when thermal energy of the
vitfil [10]

When the thermal energy of the air around a fire is transferred to the surrounding air  A. The thermal energy is spread out by the surrounding air.

Thermal energy transfers occur in 3 approaches conduction, convection, and radiation. whilst thermal power is transferred among neighboring molecules that are in touch with each other, which is referred to as conduction.

Thermal strength refers to the power contained inside a system that is liable for its temperature. heat is the go with the flow of thermal electricity. an entire department of physics, thermodynamics, offers how heat is transferred among exceptional systems and how work is accomplished in the manner.

Thermal strength also referred to as heat strength is produced when a rise in temperature reasons atoms and molecules to transport quicker and collide with each other. The energy that comes from the temperature of the heated substance is referred to as thermal strength.
