Study Notes
Temperature Measurement
- Temperature is primarily measured using thermometers that utilize the expansion of liquids or the electrical resistance of materials.
- Common scales for measuring temperature include Celsius, Fahrenheit, and Kelvin.
Heat vs Temperature
- Heat refers to the total energy of molecular motion within a substance, while temperature measures the average kinetic energy of those molecules.
- Heat is a form of energy transfer between bodies at different temperatures, whereas temperature is a property that reflects how hot or cold a substance is.
Fundamental Differences
- Heat involves the transfer of energy due to temperature difference, whereas temperature is a measure of thermal energy within an object.
- Heat is dependent on the amount of substance and its state, while temperature is an intensive property that does not change based on quantity.
Temperature During Phase Change
- When heat is added to a substance undergoing a phase change, such as melting or boiling, the temperature remains constant until the phase change is complete.
- Energy during this process is used to break molecular bonds rather than to increase temperature.
Definition of Heat
- Heat is described as the energy that is transferred from one body or system to another due to a temperature difference.
- It can be measured in joules or calories and plays a crucial role in thermodynamics and energy transfer processes.
