There are 1000 mililiters in a liter, so 1000 ml for every liter, you have 5 liters, so:
5L*1000 = 5000 mL
In a crystal, the molecules are closer together as they are in any solid. they have less room to move, and might even be combined together rather than individual
Answer :
Option A) 2.00 eV
Explanation : The conversion of J to eV is done with the following formula;

Here, we have the value of particle in terms of Joules which is 3.2 X

So, on substituting we get,

= 3.2 X

X


= 1.99 eV so, it can be rounded off to 2.00 eV.

So platinum is a transition metal. In general transition metals are reducers, which means they can give the electrons they have, to the sodium atoms. Also in chemistry we look at sub orbitals rather that shells(2,8,8). So due to the energy from heat, the d orbital split as electrons move to a higher energy level. Some of the electrons are given to the sodium ions and therefore the flame changes colour to yellow.
The excitation of the electrons is caused by them getting energy and so moving up an energy level. This energy is released and the electron returns to it's original state. The energy released, however, does not release in the same direction, but in different/various directions. Therefore the colour of the light changes as some energy is released in the surrounding.
