Ch 21 Temperature, Heat, and Expansion. Temperature A measure of the average kinetic energy of the particles in a substance.
Thermal energy is transferred through the hydrosphere from warmer latitudes to cooler polar regions largely due to global winds.
Ch. 6 – Thermal Energy I. Temperature and Energy Transfer (p. 158 – 170) Temperature Thermal Energy Heat Transfer.
Section 7.2Calorimetry & Heat Capacity Why do some things get hot more quickly than others?
How hot or cold something is Measures avg. K.E. of the particles in the object. Tool: thermometer – meas. in degrees. Scales ~ Celsius (°C) 0° - 100° ~
Accuracy and Precision With Significant Figures. Accuracy Accuracy – how closely a measurement agrees with an accepted value. For example: –The accepted.
Classify the following properties as Physical or Chemical:
Theories of Heat. all substances contain tiny, constantly moving particles Kinetic Theory.
1 Liquids and Solids Chapter 13. 2 Water Colorless, odorless and tasteless Density of ice < than density of liquid water –Not the normal trend –For equal.
Weather Dynamics Science 10 G.Burgess 2007. Our weather is dependant on the movements of air and water. Light from the sun heats the Earth and oceans.
