How do atoms become ions explain which characteristics change in which stay the same during this transformation

Which form of energy is due to the movement of electrons?

larisa86 [58]

Kinetic energy is motion of waves, electrons, atoms, molecules, substances, and objects. Potential energy is stored energy and the energy of position gravitational energy. There are several forms of potential energy. Electrical Energy is the movement of electrical charges.

I hope this helps you.

If the plant produces electric energy at the rate of 1. 5 gw , how much exhaust heat is discharged per hour?

expeople1 [14]

The amount of exhaust heat discharged per hour from the plant which produces electric energy at the rate of 1. 5 gw, is 9.36×10¹⁹ J/h.

<h3>How to calculate the heat discharged per hour?</h3>

The heat is discharged per hour is equal to the different of total power and actual power.

The plant produces electric energy at the rate of 1. 5 gw. Let assume the efficiency of this power plant is 64% between the temperature of 660 degree C to 330 degree Celsius.

Thus, the maximum efficiency is,

$\eta_{max}=1-\dfrac{660+273}{330+273}\\\eta_{max}=0.55$

The total power is,

$P_t=\dfrac{P_A}{\eta_{max}\times0.64}\\P_t=\dfrac{1.5}{0.55\times0.64}\\P_t=4.26\rm\; GW$

Thus, the heat discharged per hour is,

$Q=4.26-1.5\\Q=2.76\text{GW}\\$

Multiply the value with 3600 to convert it in s/h,

$Q=2.76\times10^9\times3600\text{ J/h}\\Q=9.36\times10^{19}\text{ J/h}\\$

Thus, the amount of exhaust heat discharged per hour from the plant which produces electric energy at the rate of 1. 5 gw, is 9.36×10¹⁹ J/h.
