The oxymoron is a combination of contradictory or incongruous words.
In this example, deafening silence.
Deafening is a noise so loud as to make it impossible to hear anything else.
Silence is oposite of deafening, complete absence of sound.

The ionization energy is energy required to remove an electron from element in it's gaseous state.
What is ionization energy?
Ionization energy is defined as the minimum energy required to remove an electron from its valence shell of an isolated gaseous atom,positive ion or molecule.Ionization energy is positive for neutral atoms from which it can be concluded that ionization is an endothermic process.
Closer are the valence electrons to nucleus ,higher is the ionization energy.It is usually expressed in electron volts or joules.Ionization energy increases from left to right in a period as more energy is required to remove electrons with small atomic size.
Ionization energy decreases down the group as atomic size increases due to which electrons are easily lost from the valence shell.

(2) 0.1 M KOH (4) 0.1 M H2SO4
Answers
Answer: (2) 0.1 M KOH
Explanation:
Thymol blue is an universal indicator. Thymol blue has a blue color when in basic conditions (pH > 7), a green color in neutral conditions (pH =7), and a yellow color in acidic conditions (pH < 7).
pH or pOH is the measure of acidity or alkalinity of a solution. pH is calculated by taking negative logarithm of hydrogen ion concentration.
0.1 M , 0.1 M
and 0.1 M
are all acidic in nature.
Thus thymol blue will appear blue in basic 0.1 M KOH.

Answers
The troposphere is the lowest layer of Earth's atmosphere.
The troposphere is heated from below. Sunlight warms the ground or ocean, which in turn radiates the heat into the air right above it.
Therefore, the troposphere is warmed by the radiated heat from the Earth's surface.
Answer:
radiated heat from the Earth's surface
