The binding energy of electrons in a metal is 193 kJ mol ^-1 .

<h3>What is binding energy?</h3>

The minimal amount of energy needed in physics and chemistry to separate a particle from a system of particles or to break a system of particles down into its component pieces is known as the binding energy.  While the word separation energy is used in nuclear physics, the former meaning is more common in condensed matter physics, atomic physics, and chemistry.

The energy level of a bound system is often lower than that of its unbound components. Relativity theory states that a drop in a system's total energy of E leads to a corresponding decrease in its total mass of m, where

Δmc² = E.

A filament at which temperature would have the most light absorbed by a piece of yellow glass?
stepladder [879]
Soft light (answer) is the filament between (2700k-3000k). 
 The higher the kelvin number the whiter the light.

3500k-4100k is bright white/cool white

5000k-6500k is daylight 

\and those are the three primary colors of color temperature

If the bag was made from a metal (like sturdy aluminum foil), do you think it would lose its heat faster or slower than the plas
Luden [163]

I think it would lose its heat faster than the plastic bags because of higher conductivity feature.

<h3>What is conduction?</h3>

Conduction is the process in which heat or electricity is transmitted or transferred through the material of a substance without movement of the material.

We know that metals are good conductors so we can conclude that it would lose its heat faster than the plastic bags bof higher conductivity feature.

Suppose a system returns to its original overall, internal energy ((∆U) after the following changes. In step 1, 25 J of work is
Brums [2.3K]

Answer:

Heat transfer in step 2 = 47.75 J

Explanation:

Internal energy = heat + work done

U = Q + W

In a cyclic process the total internal energy change of the system = 0.

In the process there are two steps. The total heat exchange in the process is the sum of heat exchanges in the two processes.

We have to find the heat exchange in step 2.

In step 1,

W = 1.25 J          Q = -37 J

U_{1} = -37 + 1.25 = -35.75 J

In step 2, the internal energy change will be negative of that in step 1.

U = 35.75 J

W = -12 J

U = Q + W

35.75 = Q -12

Q = 47.75 J

Heat transfer in step 2 = 47.75 J
