The amount of kinetic energy an object has depends on its <u>motion</u>
and mass.
Explanation:
Kinetic energy is the intrinsic energy in an object due to its motion. Kinetic energy is calculated by the formulae;
K.E = <em>0.5 </em>x <em>m</em> x <em>v²</em> whereby;
K.E = Kinetic Energy
M = mass
V = velocity
As shown by the equation, the higher the velocity of the object the higher the kinetic energy (K.E). In addition, the higher the mass of the object in motion the higher the Kinetic Energy.

Water will have higher surface tension.
Explanation:
There are strong hydrogen bonds and strong intermolecular forces present in water. Water is polar in nature that is why surface tension is present in it. The force of attraction between the particles is the main factor for surface tension.
The cohesion force in the liquid causes surface tension.
Since the other substance is acetone which does not form strong intermolecular forces hence it has low value of surface tension. They have low cohesive forces and get stick to the surface and are spilled instead of attaining minimal volume.
It is primarily, from this list, nitrogen and carbon that trap infrared energy, although the extent to which this happens is determined by many other factors, such as heat. :D
Answer is: True.
Example for p<span>olyhydroxyl alcohol is glycerol.</span>
Glycerol (1,2,3-Propanetriol, glycerine<span> or glycerin) is a simple polyol (it has three hydroxyl group) compound with formula (OH-CH</span>₂-CH(OH)-CH₂OH or C₃H₈O₃).
The glycerine <span>backbone is found in
all lipids known as triglycerides. (ester derived from glycerol and three fatty acids).
Glycerol is soluble in water and it is hygroscopic.</span>
