Answer 1

Answer: a. conduction

b. convection

c. radiation

d. conduction

e. conduction

f. convection

g. convection

h. radiation

i. conduction

j. conduction

k. radiation

l. convection

m. conduction

n. radiation

o. conduction

Explanation:

Answer 2

Answer:

1-Conduction , 2- Convection 3-Radiation , 4 -Conduction ,

5 - Convection , 6 -Convection , 7 -Radiation , 8 - Radiation ,

9 -Convection , 10 - Conduction ,11-Radiation , 12 -Conduction,

13 -Convection ,14 - Radiation and 15- Conduction .

Explanation:

In conduction, heat transfer  between objects is caused by direct contact. Convection causes heat transfer  within the liquid. In radiation, heat transfer is generated by electromagnetic waves without the involvement of particles.

Now ,

1) A snowball in your hand - Conduction

2)Warm and cod air meeting - Convection

3)Sum ray warming a puddle - Radiation

4)An egg on a hot skillet - Conduction

5) Pouring cold water in your hot coffee - Convection

6) Using your blow dryer - Convection

7) A heater heating of  the inside of the car - Radiation

8) The sun warming of a rock -  Radiation

9) A pan boiling water on the stove - Convection

10) Using a curling iron to curl your hair - Conduction

11) Feeling the suns heat on your back - Radiation

12)Butter melting on warm pancakes - Conduction

13)Adding hot water to your cold bath water - Convection

14) Baking a cake inside the oven - Radiation

15) Ironing wrinkled shirt - Conduction
