5. 6.1.1 The objective is to define the
Physical Quantity that measure DEGREE OF HOTNESS of a body
SI Unit = KELVIN (K)

6. How to measure Temperature?
THERMOMETER

7. 6.1.1 The objective is to define the
ENERGY (Therma) that FLOWS naturally from HOT body to COLD body
SI Unit = JOULE (J)

8. 6.1.2 The objective is to describe the process of

9. 6.1.2 The objective is to describe the process of
CONDUCTION
Transfer of heat
by the direct
contact of
particles of
matter
Examples:
Gold, Copper, Iro
n, Aluminum

10. 6.1.2 The objective is to describe the process of
CONVECTION
Up and Down
movement of
liquid and gases
caused by heat
transfer.
Examples:, warm
er water, Hot air
balloon

11. 6.1.2 The objective is to describe the process of
RADIATION
Transfer of heat
by
Electromagnetic
waves
through space
Examples: Cell
Phone wave,
Sunlight, Nuclear

12. 6.1.3 The objective is to define

13. 6.1.3 The objective is to define

14. 6.1.4 The objective is to apply the concept and formula in solving problems
Question 1
How many joules of heat are required to raised the
temperature of 750 kg of zinc to raise its temperature from
25’C to 275’C? (specific heat capacity of zinc is 390 J / kg ‘C)

15. 6.1.4 The objective is to apply the concept and formula in solving problems
Question 2
150 g of water is at 140’C. How much heat must be removed to
lower the water to 75’C ?
(Specific heat capacity of water is 4.20 kJ / kg’C

16. 6.1.4 The objective is to apply the concept and formula in solving problems
Question 3
A 0.23 kg sample of Aluminum is provided with 4500 joules of
heat energy. What will be the change in temperature of this
sample?

17. CONCLUSION
* TEMPERATURE is a Physical Quantity that measure DEGREE OF
HOTNESS of a body. SI Unit = KELVIN (K)
* HEAT is ENERGY (Therma) that FLOWS naturally from HOT
body to COLD body. SI Unit = JOULE (J)
•HEAT TRANSFER methode is refer to
CONDUCTION, CONVECTION & RADIATION
•HEAT CAPACITY formula is
Q = mc Δϴ
