Law of Conservation of Energy worksheet PDF can be downloaded free of cost. The Law of Conservation of Energy was proposed by Sir Isaac Newton in 1671. It is a physical law based on the concept of energy.
In Physics, the term ‘mass’ refers to the amount of energy in a system. The Law of Conservation of energy defines the relationship between force and the amount of mass that has been put into a system. If the mass of a system is greater than the force that acts upon it, the system will tend to maintain its original position. If the force acting upon a system is equal to or less than the mass of the system, the system will tend to change its position. Thus, the Law of Conservation of Energy acts upon a system of equilibrium.
Energy and Mass are two factors that are used in balancing the forces and are known as the first law of thermodynamics. Energy is a phenomenon in physics, which is measured in Joules or Calories. Energy can be used to store or release power. The Laws of Thermodynamics are mainly defined by this law and state that the heat from an object is constant at all times.
There are three sources of energy in the universe. Energy comes from heat, motion and radiation. When one of these three factors is increased, the other two decrease. This is the basis of conservation of energy, where any increase in one of the three factors means that the other two are also decreasing.
When we convert heat to electricity, we produce heat, which is then transformed into mechanical energy, which is the thermo-chemical reaction. When we use energy to create motion, we use energy, which is then transformed into kinetic energy, which is the motion. Radiation energy is the result of converting electric energy into electromagnetic energy. Atoms and molecules are converted into various forms of energy through the laws of thermodynamics. When one of the elements is present in the form of its lightest and heaviest states, the element is converted into thermal energy and is released as heat.
All methods utilize electricity and mechanical energy to heat water or remove heat from water. An electric heater will work on the principle of electric energy to transfer heat to water. The process will start when water is heated, which results in gas bubbles rising into the air. Water boils in the air due to heat, which leads to a vapor, which turns into a liquid, which rises up into the glass of water. In this case, the heat from the liquid molecules is the heat source.
Solar water heaters work on the same principle, except that the solar radiation does not heat the water directly, but rather, heats the water molecules that are suspended in the outer layer of the water. As the water vapor condenses into water, the water molecules move up into the liquid, thereby cooling it down. This is the main reason why solar water heaters work. The heaters do not need heating tubes, batteries or electric circuits to function.
The Law of Conservation of Energy can also be used to calculate the amount of energy that you would have used if you had used that same amount of energy to produce the same amount of heat. Thus, the Law of Conservation of Energy worksheet PDF is used for calculating the amount of energy used by a machine, or more specifically, the amount of energy that is wasted.
