Question

i just need final answer no explanations : 

 

just mention correct options 

 

1) Which of the following is an example of convection?: *
OA) Heat radiates from a planet into space.
B) Heat travels from atom to atom from inside a planet to the outside.
C) Hot material inside a planet rises, and cool material sinks towards the center.
OD) Metal conducts energy throughout the Earth's core.
2) When does radiation stop occurring?: *
OA) When there is not a temperature difference between the radiating body and ambient
temperature.
O B) When conduction or convection is occurring
C) When there is a gaseous medium
OD) Radiation is always occurring.
3) When sleeping under a blanket in a cold room, heat from your body leaves via
conduction through your skin and then via convection throughout the air. Which of the
following most accurately describes the other heat transfer interactions occurring?: *
OA) Heat is gained by your body via thermal radiation from the blanket. The blanket increases
the rate of convection by instilling a higher difference in temperature between your body and
the ambient temperature.
OB) Heat is gained by your body via thermal radiation from the blanket. The blanket decreases
the rate of convection by instilling a lower difference in temperature between your body and the
ambient temperature.
OC) Heat is lost from your body via thermal radiation. The blanket increases the rate of
convection by instilling a higher difference in temperature between your body and the ambient
temperature.
OD) Heat is lost from your body via thermal radiation. The blanket decreases the rate of
convection by instilling a lower difference in temperature between your body and the ambient
temperature.
