And heat rises

# data[].attributes.body
Student C because they cose lift to leave the ground

# data[].attributes.body
Most people have indicated they believe Student C

# data[].attributes.body
Student C because power is what the plane and hot air balloon need to define gravity and lift up like a hot air balloon needs heat to define gravity and a plane need energy to define gravity

# data[].attributes.body
Student A is wrong because gravity is real, and
Student B is part right because gravity does pull things back down to earth, but no.
Student C is right because gravity

# data[].attributes.body
Student C because Gravity is always present and the lift is what lets the things fly

Sahar student c because gravity is real and it's not just little so the only one left and right is student c

Sahar student c because gravity is real and it's not just little so the only one left and right is student c

# data[].attributes.body
I think that Student C is correct because heat rises and makes the hot air balloon go up just like heat rises when your roasting a marshmallow that's why you put it above the fire and not in it

# data[].attributes.body
Student C is correct because, like the student said heat is holding up the hot air balloon and there is proof cause in the picture it showed the hot air balloon with heat in the middle. They are also correct because Gravity is real or else we would be flying everywhere. The airplane also uses the wings to fly the picture shows proof.

# data[].attributes.body
Because heat rises which goes into the tarp which gets the heat trapped still pushing up which makes it too strong for gravity. The way the planes wing and flaps cut through the air makes it lift also the turbines.

# data[].attributes.body
We know that gravity Is every where because we don't see anything float
I've seen planes on the ground and hot hair balloons on the ground
Also balloons only float because of helium witch is a gas. So yeah

# data[].attributes.body
Student C because the gravity help it go up.

# data[].attributes.body
Student C is right because gravity is everywhere around earth like student C said the plane uses its wings to fly and the hot airballoon uses heat to push itself up into the air. Unlike student C student is incorrect if gravity did not exist then we would be floating in the air. Student C is correct.

# data[].attributes.body
Student C
Because it's true that they earth has gravity but airplanes and hot air balloon using something to make it go up

# data[].attributes.body
C
Yes because the wings on the plane lift it and the heat does lift it for the heat.

# data[].attributes.body
Student c because the flame lets the air ballon go higher

# data[].attributes.body
I believe that this student is right because the airplane only flys because of a special "force" of wind and the air balloon only flys because of the heat flying up

# data[].attributes.body
Student C
Because for a hot air balllon the fire is hitting the ballon to make the hot air ballon rise.

# data[].attributes.body
Student C because they said that gravity is always present and

# data[].attributes.body
Student C is correct because gravity pulls us down to the earth but some things like airplanes and hotair  balloons generate energy that can make them fly like the wings on an airplane and the heat in the hotair  balloon

Student C
I think student C is right because the power and engine of the jet makes it fly.And with the hot air balloon heat always rises like a bonfire.And that's what pulls the ballon up and there is a generator and the heat goes through a tube.

# data[].attributes.body
Student c beacause planes and hot air balloons have to have heat and gravity make it fly

# data[].attributes.body
Because the

# data[].attributes.body
I think its student C because a airplane turbine has enough power going to its turbines witch makes the plane propell into the air. A hot air ballon has a generator that generates heat witch lifts up the ballon

# data[].attributes.body
student c, because planes and hot air balloons can also be on the ground, and when not powered, does not move.

# data[].attributes.body
Because the Gravity will

# data[].attributes.body
Student C
Because gravity does exist but the propellers in the wings of the plane  keeps the plane up. The heat rises so it pushes the ballon up.

# data[].attributes.body
Student C because the air plane has propellers to lift the plane.For the hot air ballon heat rises so it pushes it up.

# data[].attributes.body
Because the air plane and hot air balloon have nothing to do with gravity the plane has propellers and the hot air balloon has heat and heat rises
