Answer:
energy : the ability to cause change
work : is force x distance or when an object moves a distance due to a specific force (measured in units of newtons-meters)
potential energy : is stored energy
kinetic energy : is energy in motion
mechanicle energy : the energy of motion such as a moving vechile
thermal energy : total kinetic energy in moving partsticles, like in boiling water (energy of heat)
chemical : energy stored in chemical bonds, like in plants
electromagnetic : waves with electric and magnetic properties , such as light
nuclear energy : energy stored in the nuclear atoms

I'm not sure that's true ... we'd need to see some numbers.
But if it is true, it's the same reason why some places don't
want ladies to walk on their floors with high heels.
Pressure is (weight) divided by (area).
Pressure exerted
by a ballerina = (ballerina's weight)/(area of her toe on the floor)
Pressure exerted
by an elephant = (elephant's weight)/(area of 4 elephant feet)
Pressure exerted by
a lady in high heels = (lady's weight) / (area of 1 or 2 heels)
You can see that the greatest weight might not exert the greatest
pressure, and the smallest weight might not exert the smallest
pressure. The area is important, and it takes an awful lot of toes
or high heels to equal the area of one or more elephant's feet.
Answer:
0.900 mol/kg
Explanation:
Molality is moles of solute per kilograms of solvent.
Converting 54 grams of NaOH to moles:
54 g NaOH × (1 mol NaOH / 40.00 g NaOH) = 1.35 mol NaOH
So the molality is:
m = (1.35 mol) / (1.50 kg)
m = 0.900 mol/kg
