Phase 2 – Dynamic Understanding
► Investigation One Summary – Heat, Energy, and Temperature
In Investigation One, you studied the relationship between heat, kinetic energy of molecules, and temperature. During this Investigation, you:
1. Compared the height of room temperature liquid in a sealed glass tube when it is placed in an environment with greater kinetic energy or higher heat (boiling water).
2. Compared the level of room temperature liquid in the sealed glass tube when it is placed in an environment with less kinetic energy or lower heat (freezing water).
3. Created the graduations for your own thermometer.
4. Used the thermometer you calibrated to bring a beaker of water to three (3) different temperatures.
► Investigation One Summary – Learning Goals
Through these experiments, you concluded that:
1. Heat is the transfer of thermal energy, which includes both kinetic and potential energy. Temperature is a measure of the average kinetic energy of a substance or in an environment. When heat is transferred from areas of higher to lower heat, kinetic energy is transferred from areas of higher to lower kinetic energy (higher to lower temperature). The result is an increase in temperature in the area that once had the lower kinetic energy and decrease in temperature in the area that once had the higher kinetic energy. The transfer of heat stops when the kinetic energy (temperature) of both areas is equivalent.
2. In general, matter expands when heated and contracts when cooled because of changes in the kinetic energy of molecules. Changes in heat can also result in changes in the state or phase of matter because of changes in kinetic and potential energy of molecules.
