Answer:
Because X-rays have wavelengths similar to the size of atoms
The heat released from fission reactions is used to change water into steam. The steam then turns the blades of a turbine to generate energy. The answer will hence be B. Quickly moving neutron coming out of the reaction are slowed down by water. The water heats up and turns into steam. The steam turns the turbine and produces electricity.
Answer:
<em>What can be added to an atom to cause a nonvalence electron in the atom to temporarily become a valence electron </em>is<u><em> energy</em></u><em>.</em>
Explanation:
The normal state of the atoms, where all the electrons are occupying the lowest possible energy level, is called ground state.
The <em>valence electrons</em> are the electrons that occupy the outermost shell, this is the electrons in the highest main energy level (principal quantum number) of the atom.
So, a <em>nonvalence electron</em> occupies an orbital with less energy than what a valence electron does; in consequence, in order to a nonvalence electron jump from its lower energy level to the higher energy level of a valence electron, the former has to absorb (gain) energy.
This new state is called excited state and is temporary: the electron promoted to the higher energy level will emit the excess energy, in the form of light (photons), to come back to the lower energy level and so the atom return to the ground state.
<span>Amino acids which are known to be linked by peptide bonds they form polypeptide chains.
Proteins are linear polymers are formed by way of linking an a-carboxy group of one amino acid to a-amino of different amino acids which have peptide bond. The formation which results from two amino acids which result in a loss of a water molecule. The best process of the reaction is hydrolysis.</span>
Answer:
Option D is correct = -273 °C
Explanation:
Data given:
Temperature of absolute zero
Absolute Zero in Celsius = ?
Solution:
As we know
internationally the temperature of Absolute zero on kelvin scale = 0 K
So to convert Kelvin temperature to degree Celsius formula will used
T(K) = T(°C) + 273
Rearrange the above equation for °C
T(°C) = T(K) - 273 . . . . (1)
Put value in above eq.1
T(°C) = 0 - 273
T(°C) = -273
So,
The absolute zero in °C = -273
so option D is correct
