Out of the following given choice:
A. The increase in
the airspace occupied by vinegar molecules
B. The chemical reaction with nerves, which is slower than
other sensory processes
C. Attractive forces between the air and vinegar molecules
D. Random collisions between the air and vinegar molecules.
<span>The answer is
D. While the particles may be
moving at high velocities even at room
temperatures, the delay is due to the numerous collisions
between the vinegar molecules and the air molecules.This changes the vinegar’s
molecules directions from straight lines to random unpredictable paths</span>
Q=hc A (Ts-Ta)
q = heat transfered per unit time
A= heat transfer area of the surface
hc= convective heat transfer coefficient of the process
Ts= temperature of the surface
Ta= temperature of the air
Which pairs of matter demonstrate the laws of conservation?
The only correct ones are:
a Snowman and the melted remains of the same Snowman,
a lump of clay and the same lump broken into three pieces,
one apple and the same Apple cut into slices.
100% just had homework asking this same question got a 100% on USA TP
<span>1. Na
2. Ni
3. Na2S
4. Electrolytic Cell (Galvanic and Voltaic are synonyms, both are electric cells without an external power source.
5. 3
6. The first one
7. Na
8. Reducing agents are oxidized
hope this helps you

I believe the answer is B. Liquid water is stabilized by strong inter-molecular forces between the molecules. This is why the energy needed to completely separate the molecules converting to gas is much greater than that of converting a solid into liquid. The latent heat of vaporization will have to be higher for the liquid to become a gas.
