    remove creases. It is named for the metal of which the device is commonly made‚ and the use of it is generally called ironing. Ironing works by loosening the ties between the long chains of molecules that exist in polymer fiber materials. With the heat and the weight of the ironing plate‚ the fibers are stretched and the fabric maintains its new shape when cool. Some materials‚ such as cotton‚ require the use of water to loosen the intermolecular bonds. Many materials developed in the twentieth century

    typically bring about rotary motion. The Laws of Motion form the foundation of dynamics. First Law of Motion An object will remain at rest or continue to move at a constant velocity unless acted upon by an external force. F = net force If F = 0 ⇒ v = constant Third Law of Motion For every action there is an equal but opposite reaction. These two forces (action & reaction) act on different bodies. Freaction Faction = − Freaction Faction Second Law of Motion When a net external force acts on

    Heat of Neutralization Lab   Objective:​  The objective of this lab was to measure‚ using a calorimeter‚ the energy changes  accompanying neutralization reactions.    Background:​  Chemical changes are always accompanied by a change in energy‚ typically as  heat. If the reaction releases heat  (ΔH  <  0) then the reaction is exothermic. If the reaction  absorbs heat  (ΔH  >  0) then the reaction is endothermic. The quantity of heat is measured  experimentally by having the reaction take place in an insulated container called a

    Introduction The first law of thermodynamics states that the energy of the universe is constant. Heat is transferred when the atoms of one material vibrate and collide with the atoms of another material‚ thus transferring energy. For this reason‚ heats always travel from hot to cold objects and two objects will reach an equilibrium temperature. Materials and Methods 1. Oven 7. Test Tube 2. Pasco Temperature Probe 8.

    Law of Interaction” Law of Interaction “For every action‚ there is an equal and opposite reaction” The statement means that in every interaction‚ there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object. Interaction between the hammer and nail A hammer exerts a force on the nail and drives it into a board . But this is not the only force present for there must also be a force exerted on
