1. specific heat Capacity EQ: What is specific heat capacity? We will demonstrate understanding how to measure for specific heat. I will evaluate the relationship of the variables for the specific heat capacity equation by illustrating the equation

2. HEAT CAPACITY The heat capacity of a substance is the heat required to raise the temperature a unit degree. LeadGlassAlCopperIron Heat capacities based on time to heat from zero to 100 0 C. Which has the greatest heat capacity? 37 s52 s60 s83 s90 s 100 0 C specific heat capacity

3. LeadGlassAlCopperIron Iron and copper balls melt all the way through; others have lesser heat capacities. All at 100 0 C placed on Paraffin Slab LeadGlassAlCopperIron specific heat capacity

4. SPECIFIC HEAT Some objects are easier to heat than others. When heat flows into an object, its thermal energy and temperature increase. The amount of the increase in temperature depends on the size of the object, and on the material from which the object is made.

5. PHASE CHANGES The specific heat capacity will change depending on the state of matter. Temperature remains constant until the phase change is complete. specific heat Condensation Vaporization Freezing Melting Q liquid gas solid

6. specific heat QuantityVariableUnit Heat energy absorbed/released QJoules (J), KiloJoules (kJ), Calories (cal) Specific heatcJ/kg*K, kJ/g*˚C, J/kg*˚C massmkg temperatureTK, ˚F, ˚C

7. SPECIFIC HEAT Liquid water has a high specific heat compared to the specific heat of other substances. A mass of 1 kg of water requires 4180 J of energy to increase its temperature by 1 K. The same mass of copper requires only 385 J to increase its temperature by 1 K.

8. WHAT QUANTITY OF HEAT IS REQUIRED TO RAISE THE TEMPERATURE OF 450 GRAMS OF WATER FROM 15°C TO 85°C? THE SPECIFIC HEAT CAPACITY OF WATER IS 4.180 J/G/°C. 450 g The heat required to do this job is: specific heat example

9. 1.How much energy must be absorbed by 20.0 g of water to increase its temperature from 283.0 ⁰ C to 303.0 ⁰ C ? Use the specific heat of water in Joules. 2. If it takes 41.72 J to heat a piece of gold weighing 18.69 g from 10.0 ⁰ C to 27.0 ⁰ C. What is the specific heat of gold in J/kg. ⁰ C? specific heat example

10. CLOSING TASK You are in charge of developing a tattoo to allow the world to know about “Specific Heat Capacity” The center of the tattoo must be the equation The surrounding artwork (minimum of 4 colors) must demonstrate the equation’s concept in a real-life situation. The artwork must be suitable for all ages and appropriate for viewing in all social situations A 5 sentence paragraph explainingg how the artwork represents the equation or “Specific Heat Capacity”
