Elements is the simplest form of a pure substance.They cannot be broken down into any thing else ,by either physical or chemical means.In contrasts compounds are pure substances like elements ,they are made up of two or more elements.Just like elements they can be broken down into simpler substances by chemical means,but unlike elements they can only be broken down by chemical means .not both physical and chemical means like elements can.

B.
Refrigerants should be handled using approved equipment only.
Force = mass * acceleration
Here is an equation for force, used to calculate force.
Look at it this way:-
Joules is used to measure force, while mass is measured by kg. Acceleration is measured by m/s/s (meters per second per second, or meters per second squared.)
joules = m/s/s * kg
Which makes everything fit in just right! :D
