Temperature vs Heat

• Temperature is the average kinetic energy of the individual particles produces an effect we sense as warmth.
• The quantity that indicates warmth with respect to some standard that is called temperature.
• We can express temperature by a number that corresponds to its degree of hotness or coldness on some chosen scale
• celcius' boiling point is 100 and it's freezing point is 0
• Fahrenheit's boiling point is 212 and its freezing point is 32
• Kelvin's boiling point is 373 and its freezing point is 273
• Heat transfer is the direction of spontaneous energy transfer from warmer object to cooler object
• Heat is the energy transferred from one to another due to temperature difference
• Matter contains both potential and kinetic energy inside is called internal energy.
• Heat flow depends on temperature difference, amount of material, & mass
• Calorie is the amount of heat required to change temperature of 1 gram of water
• Thermodynamics is the study of relationship between thermal energy, heat, & work
• materials expand when temperature increases
• Linear Thermal Expansion is when the temperature changes, the length is directly proportional to change of temperature and length
• Area Thermal Expansion is when the temperature changes, the area is directly proportional to change of temperature and original area
• Volume Thermal Expansion is when the change in volume is directly proportional to the original volume & change in temperature
• Thermal Expansion is the tendency of an object to change its dimension either in length, density, area, or volume due to change of temperature
