in the plate heat exchanger there is gaskets in between every part so this part become weak part in heat echanger and there is possibilities of leakage through this part, there is no such problem in shell and tube type.
the plate type cant be used when there is high temperature and high pressure drop but shell and tube type can be used
in evaporation there the liquids change into vapors due to which there is sudden change in pressure and in which plate type is not used because there is chances of leakage

In order for an atom to be neutral (i.e. have no charge), it must have the same number of ______ as it has protons. a. neutrons

Marina CMI [18]

Answer : The correct option is, (b) There is a same number of electrons.

Explanation :

For the neutral atom, the number of protons and electrons are equal. But, they are unequal when the atoms present in the form of ions or the atom has some charges.

When an unequal number of electrons and protons then it leads to the formation of ionic species.

Ion : An ion is formed when an atom looses or gains electron.

When an atom looses electrons, it will form a positive ion known as cation.

When an atom gains electrons, it will form a negative ion known as anion.

For example : The neutral atom Mg has equal number of protons and electrons i.e 12 but $Mg^{2+}$ ion has unequal number of protons and electrons that means it has 12 number of protons and 10 number of electrons.

Hence, the correct option is, (B) electrons
