Term | Definition |
---|---|
conclusion | a summary and interpretation of results that explains how and why the outcome occurred |
conduction | the transfer of thermal energy between objects through direct contact |
convection | transfer of thermal energy within a fluid due to temperature differences |
convection current | a type of air current that develops as cooler and warmer particles move in a cycle |
dense | less compact |
dependent variable | the variable on the y-axis/output and is the effect or change you want to observe |
energy transfer | occurs when matter with higher kinetic or thermal energy interacts with matter that is lower in energy; energy moves from high to low |
heat | energy transferred within a substance or from one substance to another; always flows from a warmer area to a cooler area |
independent variable | the variable on the x-axis/input and cause changes |
insulator | a material that is not good at conducting thermal energy transfer |
kinetic energy | the energy of motion |
mass | the amount of space matter takes up |
modifications | changes made |
potential energy | energy from position; solid particles have lower potential energy since they are close together; liquids and gases have higher potential energy since they have more space |
radiate | distribute heat to surroundings |
radiation | the transfer of energy in the form of waves through matter or through empty space |
reasoning | an explanation of the data and how that supports your conclusion |
temperature | a measure of the average kinetic energy of the particles in an object due to their random motions |
thermal energy | the total energy of the particles of a substance |
