Heating a metal from room temperature to pouring temperature in a casting operation depends on all of the following properties e
lapo4ka [179]

Answer:

(e) thermal expansion

Explanation:

The density, the heat of fusion and the melting temperature of the metal are determining characteristics to take into account to raise the temperature of the metal from room temperature to the melting temperature. Since they will determine the following:

Density: is the relationship between the mass of a body and the volume it occupies in outer space.

Heat of fusion: The enthalpy of fusion or heat of fusion is the amount of energy needed to make a mole of an element that is at its melting point pass from the solid state to the liquid, at constant pressure.

Melting temperature is defined as the temperature at which the phase transition from the solid state to the liquid occurs at normal atmospheric pressure.

While the dilution of metals will only have an influence on the volume it will occupy but not on the heating process

When a 4.25 kg object is placed on top of a vertical spring, the spring compresses a distance of 2.62 cm. what is the force cons
ANTONII [103]
The force applied to the spring is the weight of the object that compresses it, so it is equal to:
W=mg=(4.25 kg)(9.81 m/s^2)=41.7 N

Because of this force, the spring compresses by x=2.62 cm=0.0262 m. Using Hook's law,
F=kx,
since we know the intensity of the force (the weight W) and the compression of the spring, x, we can find k, the spring constant:
k= \frac{F}{x}= \frac{W}{x}= \frac{41.7 N}{0.0262 m}   =1591.6 N/m

The diagram is a real world example of the first and second laws of thermodynamics. It shows how thermal energy is used to gener
Dmitriy789 [7]

Answer:

First law: kinetic energy is used to turn an electric generator

Second law: some thermal energy is lost to the environment as it travels through the system

Explanation:

The first law of thermodynamics is known as the law of conservation of energy. It states that energy can neither be created nor destroyed but can only be transferred or changed from one form to another. When thermal energy is used to generate electricity, the kinetic energy of the steam is used to turn the electric generator (thereby producing electrical energy).

The second law of thermodynamics states that energy transfer or transformation leads to an increase in entropy resulting in the loss of energy. This law also states that as energy is transferred or transformed, some is lost in a form that is unusable. When thermal energy is used to generate electricity, some of the thermal energy is lost to the environment as it travels through the system.
