Among the given mediums, Vaccuum is the best thermal insulator to reduce the transfer of thermal energy by radiation as there will be no air particles which carries heat from one place to other. Hence, Option (D) will be the correct option
<h3>What is Heat radiation ?</h3>
Heat Radiation refers to the transfer of heat from a hot body to cold body directly, without heating the medium between two bodies.
Vaccum does not have any particles in it. Thus, there will be no transfer of heat through it.
The best example of it is thermous flask in which vaccuum inside thermous flask reduces the transfer of energy through it.
Hence,Among the given mediums, Vaccuum is the best thermal insulator to reduce the transfer of thermal energy by radiation as there will be no air particles which carries heat from one place to other. Thus, Option (D) will be the correct option

The given blanks can be filled with meteorology, atmosphere, biosphere, SI, and scientific notation.
In the field of meteorology, scientists measure the pressure, temperature, and humidity. Their measurements come from the characteristics of the atmosphere, and hydrosphere, and they look at how the weather influences the biosphere and the geosphere. The units of their measurements come from SI and the metric system. The numbers usually are not large, so scientific notation is not used.
Answer:
NaOH
Explanation:
Look at charge Na has +1 charge and Ca has +2 charge after dissociation . Greater charge Stronger lattice. And as we need weak Lattice, so NaoH is stronger base than Ca(OH)2.
Answer:
Ground state electronic configuration of oxygen atom is as follows - is 1s2 2s2 2p2x 2p1y 2p1z 1s2 2s2 2px2 2py1 2pz1
Ground state electronic configuration of hydrogen atom is 1s1 1s1
Explanation:
As per the Valence Bond Theory (VBT),
Ground state electronic configuration of oxygen atom is as follows - is 1s2 2s2 2p2x 2p1y 2p1z 1s2 2s2 2px2 2py1 2pz1
Ground state electronic configuration of hydrogen atom is 1s1 1s1
Considering the electronic configuration, H-O-H bond angle would be at 90 degrees as 2py2py and 2pz2pz are oriented 90° with respect to each other. But if the oxygen atomic orbitals is used directly then bond angle for water is 104.45° as per the VSEPR theory which states that 2s2s spherical orbit in oxygen can adjust the bond angle by creating new hybrid orbitals
