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
Yes, walking involves converting chemical energy from food into mechanical energy through muscle contractions. Heat is also produced as a byproduct of this process, representing a conversion of some thermal energy.

What does friction convert mechanical energy into?
Friction converts mechanical energy into thermal energy, causing the surfaces in contact to heat up as a result of the resistance to motion.
What are five examples that illustrate mechanical energy being converted to thermal energy?
Friction between moving parts in a machine can convert mechanical energy into thermal energy. When brakes are applied in a moving vehicle, mechanical energy is converted to thermal energy due to friction between the brake pads and the wheels. The act of rubbing your hands together generates heat by converting mechanical energy into thermal energy. Electric heaters convert electrical energy (which is ultimately derived from mechanical energy in power plants) into thermal energy, which in turn heats up a room. When a ball bounces repeatedly on the ground, mechanical energy is gradually dissipated as thermal energy due to internal friction within the ball and between the ball and the ground.
Is it possible to convert internal energy to mechanical energy?
Yes, examples are steam turbines, locomotive, hydraulic turbines, etc.
What energy does friction convert to mechanical energy?
Friction converts kinetic energy into thermal energy due to the heat generated by the interaction of surfaces in contact.
Is mechanical energy coming from light and heat?
Mechanical energy does not come directly from light and heat. Light and heat are forms of energy, but they do not typically convert into mechanical energy. Mechanical energy is typically associated with the motion or position of an object.
How do you convert thermal energy to mechanical energy?
heat engine
Heat engines are devices that convert thermal energy into?
mechanical engergy
Does a refrigerator convert thermal energy to mechanical energy?
Yes coolant is used in a cycle
What does friction convert mechanical energy into?
Friction converts mechanical energy into thermal energy, causing the surfaces in contact to heat up as a result of the resistance to motion.
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.

Does wind turbins convert potentia lenergy kinetic energy or thermal energy into its original potential energy?
Wind turbines convert the kinetic energy of the wind into mechanical energy, which is then transformed into electrical energy. They do not convert energy directly back into potential, kinetic, or thermal energy.
Is mechanical energy coming from light and heat?
Mechanical energy does not come directly from light and heat. Light and heat are forms of energy, but they do not typically convert into mechanical energy. Mechanical energy is typically associated with the motion or position of an object.
Is thermal energy ever completely convertible to mechanical energy?
No, thermal energy cannot be completely converted to mechanical energy without limitations. This is due to the second law of thermodynamics, which states that some energy will always be lost as heat in any conversion process.
What can thermal energy convert into?
Thermal energy can be converted into alot of things just go find out what it is.
