I would say the head and heart because if you swim deep in the ocean you will feel pressure in your heart and head because the muscles in your body are closing in on them
hope i helped
According to this formula :
ΔTf= i Kf m
i is van't Hoff factor= 1
Kf = 1.86
m the molality we need to assume it
m= x moles of C2H5OH / Kg of mass
∴ 15 = 1 * 1.86 * ( x moles of C2H5OH/ 0.45 kg)
∴X = 3.629 moles
mass = no.of moles x molar mass of C2H5OH
= 3.629 X 46 = 167 g
∴the volume = mass / denisty
= 167 / 0.7893 = 211.57≈ 212 mL

The substance that needs more energy to undergo an increase of 25°C will
have a higher specific heat, because energy depends directly on
specific heat.
Q = cm∆T
where c = specific heat of the substance,
m = mass
∆T = temperature difference </span>
C2H6 is the most polarizable and other two are non-polar molecules
