Define energy, distinguish types of energy, and describe the nature of energy changes that accompany chemical and physical changes; Distinguish the related properties of heat, thermal energy, and temperature; Define and distinguish specific heat and heat capacity, and describe the physical implications of both
Examples of potential energies are electrical energy and gravitational energy. Light is potential energy due to moving electric and magnetic fields. Chemical energy is potential energy stored in chemical bonds in electrostatic potential energy. Gravitation potential energy is due to position or height relative to the earth.
This chapter introduces you to thermochemistry, a branch of chemistry that describes the energy changes that occur during chemical reactions. In some situations, the energy produced by chemical reactions is actually of greater interest to chemists than the material products of the reaction.
The sun is a very essential source of renewable energy in our life. Our sun is a star i.e. its light is internally produced, it does not reflect the light of any other star or body. It is the basic source of heat and light for the entire living world and the source of energy for all ecosystems.
LEARNING OBJECTIVES. Define energy, distinguish types of energy, and describe the nature of energy changes that accompany chemical and physical changes. Distinguish the related properties of heat, thermal energy, and temperature. Chemical changes and their accompanying changes in energy are important parts of our everyday world.
Energy Basics | Chemistry for Majors. Learning Outcomes. Define energy, distinguish types of energy, and describe the nature of energy changes that accompany chemical and physical changes. Distinguish the related properties of heat, thermal energy, and temperature.
The Sun is the major source of light for the earth. The sun is a massive ball of fire, at the centre of which nuclear fusion produces massive energy. This energy comes out as heat and light.
