The answer is B because isotopes have the same number of protons and neutrons.
<span>Naphthalene has a higher melting point than biphenyl because naphthalene is a polar compound while biphenyl is a non-polar compound.</span> Studies show <span>that polar compounds have higher melting and boiling points than nonpolar compounds. It is because polar compounds have strong intermolecular forces.</span>
Yesssssssssssssssssssssss
Q=mcθ
m= 0.0775 kg
c= 4184 J·kg−1·K−1.
θ= T(final) - T(initial), 95-(-8)
Q=33398.78 J so kJ divide 1000
= 33.39878 kJ
Answer:
Transfer of heat between two objects that are touching.
Explanation:
Conduction is the process by which heat is transferred from one object to another object that is touching and has different temperatures.
Eg: We can use a hot water pack to warm our back. Or While cooking we can feel the conduction process when heat process from the bottom of the pan to the top of the pan
