How does the air which is in a balloon escape from that balloon?
A balloon is stretchy. Therefore, when air is not being forced in, the ballon will try to contract to more or less of it's original size. When this happens, the air is forced out of a balloon until the molecular structure of the balloon is simillar to how it started out.
What is being transported as the waves move through matter or space?
The energy is being transported. In the case of a light wave, it is electromagnetic energy. In the case of a sound wave, it is sound energy. (The matter is not being transported, only the energy.)
As energy is being converted through it's many forms it is continuously lost through?
Heat
What makes a hot air balloon float?
A hot air balloon is able to float because the hot air being released into the balloon is less dense than the colder air surrounding it. Basically, the burner under the hot air balloons fills the balloons with hot air, enabling the balloon to rise through the cooler air outside.
Why don't balloons pop when pricked through tape?
The tape acts as reinforcement and prevents the hole from the pin to become a rip that bursts the balloon. Without the tape stuck onto the balloon the needle prick would allow the rubber tension to rip itself apart because of the air pressure stretching the rubber which would be in tension. The tape stops the balloon being able to split and so it doesn't burst. It used to be a kids trick to put 2 pieces of tape on opposite sides of a balloon and then push a long knitting needle right through the balloon without bursting it.
What type of energy is represesnted by a log floating down a river?
Kinetic energy (the energy of motion). There is also potential energy being converted into kinetic energy.
What are the energy conversions of a floating lantern?
If the water in which it is floating is moving, then the kinetic energy (movement energy) of the water is causing the lantern to drift. At the same time the lantern's flame is produced from wax or oil, and this material is being changed from chemical energy (energy of composition) to light energy (the flame).
Does the buoyant force on a submerged inflated balloon increase as it sinks?
No, it actually might decrease due to balloon being compressed by pressure. Floating objects are governed by Archimedes Principle which states that the weight of a floating object is equal to the water it displaces. A corollary of Archimedes Principle is that the buoyant force acting on an object is equal to the volume of water displaced. Therefore, when a balloon is compressed as it submerges it displaces less water and the buoyant force decreases proportionately.

Why can a balloon survive being skewered?
It can survive because the rubber is thicker at the two ends and the skewer can go through them
How can you tell if energy was involved somewhere?
When ever there is a change, no matter how small, this involves energy. Energy is involved everywhere around us, we just do not see it or count on it being some form of energy. Even dust floating in the air transforms and uses energy.
Is a path for the transfer of matter and energy through an ecosystem by eating and being eaten.?
Biochemical cycles are the main means of energy transfer through an ecosystem. The transfer of energy by eating and being eaten is called the food chain.
Electricity traveling through a wire is an example of what?
Energy being transferred from place to place

As energy is being converted through it's many forms it is continuously lost through?
Heat
What energy is created from the wind?
In the turbine, mechanical energy is created. After being converted through a special generator, electrical energy is created.
How is the balance of energy maintained through the transfer of heat?
It isn't. If heat is being transferred then there is an unbalanced energy gradient.
