What is the principle of conservation of thermal energy?
There is no such principle. Thermal energy can convert to other forms of energy, and vice-versa. The TOTAL energy (thermal + other kinds of energy) is conserved in a close system.
What is the study of how energy is conserved and transferred?
Most of that is covered in thermal dynamics. Also, most physics books actually have a section called energy conservation.
Is mechanical energy always conserved why or why not?
no it's not cuz if there is friction energy wont be conserved
In a collision what is conserved?
Momentum is conserved in a collision. If two cars have the same mass and are traveling at the same speed and collide headfirst, the momentum of both cars cancel each other out and they will be motionless. If one has greater speed or mass than the other, it will still have the difference in momentum after the collision.
Does fire need energy?
No because it already is an energy.

How can energy change forms and is conserved?
Conservation just means the energy doesn't disappear. So for example as kinetic energy is changed to thermal energy, no energy is ceasing to exist. It's just becoming a different form.
Is machanical energy always conserved?
No. Total energy is always conserved, but not so mechanical energy.

How can energy be conserved if a substance must gain or lose thermal energy to change state?
Heat is a form of energy. It is just being transferred to the temperature bath (air, water, whatever). It hasn't been destroyed.
Does fire need energy?
No because it already is an energy.
The total amount of energy before and after a chemical reaction is the same .Thus energy is what?
Therefore energy is conserved.
How is friction related to the law of conservation of energy?
When an object slows down because of friction, its energy is not lost but merely transferred to thermal energy. Since energy naturally disperses as much as possible, the thermal energy gets dispersed throughout the atmosphere. Even though the energy is no longer usable it is still conserved. *see the second law of thermodynamics
