PPT-Energy and Temperature Scales

Calculations and Conversions Are Heat and Temperature the Same HeatAmount of energy that an object has Temperaturemeasurement of the kinetic energy that an object has Fahrenheit o F is the symbol used for this unit. For example if two di57372erent sized containers 64257lled with di57372erent gasses at di57372erent pressures and temperatures are brought into thermal contact after a period of time the 64257nal volumes pressures entropies enthalpies and other ther Heat Energy. Heat energy is due to the movement of atoms or molecules.. As atoms move faster they create more energy = causing Heat!. Thermal Energy. Depends upon the mass, temperature and phase of an object.. Gregory . Falkovich. Weizmann Institute of Science, Israel. April 01, 2013, Berkeley. “The answer is blowing in the wind”. Only normal forces. S. S’. Horizontal temperature . gradient causes wind. Kelvin, Celsius, Fahrenheit. Fahrenheit. In the 1700s, G. Daniel Fahrenheit developed a scale used by meteorologists for measuring surface temperature. The scale was named for the developer, and the unit of measure has become known as degree Fahrenheit (F°). changes.. 18/08/2017. Starter. Estimate. the temperature in each of the pictures:. 3. o.

The transfer of thermal energy . Not a measure of energy but rather of energy transferred. . Measured in terms of joules or calories (cal). . Calories relate heat to changes in temperature. . Calorie is defined as the amount of heat needed to raise the temperature of one gram of water by one degree Celsius. . Discovery Education Video:. This clip introduces heat, energy, and temperature. Some key terms and concepts are introduced. . Heat is a form of energy . that we can feel.. What is heat?. What is heat?. And Heat . Is Transferred. EQ: How can heat be transferred from one place to another?. Temperature. The weather report says that today’s high temperature will be 48 degrees and it will be cloudy. What should you wear?.

Explain the . Section 4: Thermal Energy Chapter 3: Matter and Energy Learning Objectives Convert between Fahrenheit, Celsius, and Kelvin temperature scales. Relate energy, temperature change, and heat capacity. Thermal Energy Work = force x distance. The ability to do . work.. Work - . cause a change or move an object.. Many types- all can be changed into the other.. Energy. Potential. - stored energy. Position, condition or composition. Learning Goal . . Given a temperature, calculate a corresponding temperature on another scale.. 3.3 Temperature. Temperature . is a measure of how hot or cold an object is compared to another object.. In fact, the atmosphere receives very low amount of heat energy from the sun as it receives most of its energy from the long wave terrestrial radiation.. Atmosphere receive energy from the sun and the earth in different ways. . Objectives: After finishing this unit, you should be able to:. Work with Celsius, Kelvin, and Fahrenheit temperature scales for both specific temperatures and temperature intervals.. Write and apply formulas for linear, area, and volume expansion..
