Energy and Matter
Knowledge
Students know:
- Various factors affect the transfer of energy.
- The relationship between the temperature and the total energy of a system depends on the types, states, and amounts of matter present.
- The amount of energy transfer needed to change the temperature of a sample of matter by a given amount depends on the nature of the matter, the size of the sample, and the environment.
- Temperature is related to the average kinetic energy of particles of matter.
- Temperature, when measured in Kelvin, is directly proportional to average kinetic energy.
Skills
Students are able to:
- Organize given data to allow for analysis and interpretation to determine how various factors affect energy transfer.
- Analyze the data to identify possible causal relationships between various factors and energy transfer.
- Interpret patterns observed from the data to provide causal accounts for events and make predictions for events by constructing explanations.
Understanding
Students understand that:
- The relationship between the temperature and the total energy of a system depends on the types, states, and amounts of matter present.
- Various factors, such as the state of matter, the amounts of matter present, and the environment, affect the amount of energy transfer needed to change the temperature of a sample of matter. A measure of temperature can indicate the amount of energy transfer.
