What is the difference between temperature and heat? i know that heat is a form of energy and temperature is required to change the energy of a system, but essentially what differs these two quantities?

The important difference is that temperature is a measurement quantity that can be inserted in a formula (or recipe), while heat is a relative term, not a scientific term, and is, as the questioner suggests, the energy in a substance or process, caused by, residing in, or sustained by the movement of molecules.  Anything with a temperature high than absolute zero (-274 Kelvin) has some thermodynamic energy (the scientific term for heat).  The confusion lies in the terms used for the physical state, as opposed to the man-made measurement of that energy.  Heat is also the name for one kind of energy, and that energy can be transformed to other kinds:  kinetic, electrical, etc.  “Heat” is also a member of the general English vocabulary, usually paired in the duality “heat-cold”, not exactly polar opposites, but applicable in context.   The terms may be applied at many temperatures:  “cold tea”, “cold weather” “hot tea”, hot weather”, and as a metaphor: “cold case” “hot date”, etc.; temperature, however, cannot.
