determine the potential energy stored in a spring if a force of 28 holds the spring and it has a spring constant of 97 N/m compressed.

please answer in joules and explain how you solved It. (like dumb it down) so that I could learn. thank you!

Expert Solution

The force on a spring is given by

                                       

And the potential energy stored in the spring is

                                        

Where k is spring constant (here k = 97 N/m), and x is expansion/compression in spring.

Given that a 28 N force is holding the spring. So we can write

                                           

                                    or,   

Therefore, the potential energy stored in the spring is

In chemical reactions, heat is converted into chemical energy (the potential energy stored in chemical bonds) or vice versa. Bond energy is the energy required to break one mole of the bond in the gas phase. Since it takes energy to break a bond, bond energies are always positive. Conversely, energy is released when bonds are formed. Thus, the enthalpy change for a reaction can be approximated from ΔHrxn=∑(ΔHbreaking)+∑(ΔHforming) where H represents bond energies for the breaking (positive bond energy)...
