Final exam Chem

the lowest temperature possible. At a temperature of absolute zero there is no motion and no heat. Absolute zero occurs at a temperature of 0 degrees Kelvin, or -273.15 degrees Celsius, or at - 460 degrees Fahrenheit

• Absolute zero

• Chemical potential energy

• Closed system

• Conduction

the energy stored in the chemical bonds of a substance

• Absolute zero

• Chemical potential energy

• Closed system

• Conduction

a system that can exchange only energy with its surroundings, not matter

• Absolute zero

• Chemical potential energy

• Closed system

• Conduction

the transfer of heat energy through matter from particle to particle; most effective in solids

• Absolute zero

• Chemical potential energy

• Closed system

• Conduction

the transfer of heat energy in gases or liquids due to density differences

• Convection

• Elastic potential energy

• Electromagnetic energy

• Endothermic reaction

potential energy stored as a result of deformation of an elastic object, such as the stretching of a spring

• Convection

• Elastic potential energy

• Electromagnetic energy

• Endothermic reaction

the type of energy which comes from electromagnetic waves

• Convection

• Elastic potential energy

• Electromagnetic energy

• Endothermic reaction

any process which requires or absorbs energy from its surroundings, usually in the form of heat

• Convection

• Elastic potential energy

• Electromagnetic energy

• Endothermic reaction

a process or reaction that releases energy from the system to its surroundings, usually in the form of heat, but also in a form of light, electricity, or sound

• Exothermic reaction

• Energy

• Entropy

• Isolated system

the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object. It is a conserved quantity; the law of conservation of this states that it can be converted in form, but not created or destroyed.
