Thermal energy=Mechanical energy (energy conservation law) (ALL energy is conserved, none lost)
(mass)(gravity)(height))+((1/2(mass))(velocity)^2)=(m)(C)(Δ T)+(m)(Lf)
THERMAL ENERGY=(mass)(Specific heat)(Δ Temperature)+(melting temp)(mass)
TE=(m)(C)(&Delta: T)+(m)(Lf)
Mechanical energy= potential energy + kinetic energy
Me=((mass)(gravity)(height))+((1/2(mass))(velocity)^2)
example: a piece of lead is found on the street melted. it is 130kg and 655 Kelvins and has a melting temperature of 23 ( Joules/kilograms ) and a specific heat of .13 (Joules/kilograms kelvins). how high was it dropped from if it was 300 Kelvins when dropped
Δ T=655-300
mass=130
c=.13
Lf=23
h=?
G=10
(130kg)(.013J/kgK)(355K)+130kg(23000J/kg)=(130kg)(10N/KG-M/S)(height)
2 990 599.95=(1300 N/m-s)(height)
divide by 1300
2300.4615 meters=height

What does friction convert mechanical energy into?
Thermal energy, commonly known as Heat.
What energy does friction convert to mechanical energy?
Thermal energy commonly known as heat.
What does thermal energy convert to?
Thermal energy is just heat. To convert it to mechanical energy you need some sort of heat engine, like an internal combustion engine or a gas turbine.
Is thermal energy ever completely convertible to mechanical energy?
No. You can only convert thermal energy to other types of energy if you have a difference of temperatures between two objects, and then you can only convert part of the thermal energy. The remainder will flow from the hotter object to the colder object.
When you rub your hands together on a cold day you use friction to convert kinetic energy into thermal energy?
You are converting mechanical energy into thermal energy. This is why your hands will feel warmer after rubbing them together.
How do you convert thermal energy to mechanical energy?
heat engine
Heat engines are devices that convert thermal energy into?
mechanical engergy
What does friction convert mechanical energy into?

Does a refrigerator convert thermal energy to mechanical energy?
Yes coolant is used in a cycle
What does thermal energy convert to?
Thermal energy is just heat. To convert it to mechanical energy you need some sort of heat engine, like an internal combustion engine or a gas turbine.
What causes some mechanical energy to change to thermal energy?
Normally, friction between moving surfaces causes mechanical energy to convert to thermal energy (heat), as in the brakes of most cars.
Is thermal energy ever completely convertible to mechanical energy?
No. You can only convert thermal energy to other types of energy if you have a difference of temperatures between two objects, and then you can only convert part of the thermal energy. The remainder will flow from the hotter object to the colder object.

You are converting mechanical energy into thermal energy. This is why your hands will feel warmer after rubbing them together.
How do you convert thermal energy into radiant energy?
i think you can not convert thermal energy into radiant energy
What is an example of the transfer from thermal energy to mechanical energy?
steam engine mechanism.(converts thermal energy to mechanical.)
