How do you convert megawatts thermal to Btu?
To convert megawatts thermal to Btu, you can use the conversion factor of 1 MW (thermal) = 3,412,141 Btu/h. Therefore, to convert, simply multiply the number of megawatts thermal by 3,412,141 to get the equivalent in Btu.
What is an example of converting gravitational energy into thermal energy?
An example of converting gravitational energy into thermal energy is when a meteor enters Earth's atmosphere. As the meteor falls, its gravitational potential energy is converted to kinetic energy. Upon impact with the Earth's surface, this kinetic energy is converted into thermal energy, generating intense heat that vaporizes the meteor and surrounding materials.
Which energys go into potential or kinetic energy mechanical thermal electrical chemical nuclear gravitational motion radiant or sound?
Potential energy - gravitational, chemical, nuclear Kinetic energy - mechanical, thermal, electrical, motion, radiant, sound
How does thermal energy converted into gravitational potential energy?
Thermal energy can be converted into gravitational potential energy through a process involving the use of a heat engine to lift an object against gravity, thereby storing potential energy. An example could be using a heated fluid to drive a turbine that lifts water uphill, converting thermal energy into gravitational potential energy in the water's elevated position.
Which two processes can generate energy to help a star maintain its internal thermal pressure?
Nuclear fusion is the primary process in stars that generates energy by fusing lighter elements into heavier ones. Gravitational contraction is another process where a star generates energy by converting gravitational potential energy into thermal energy. Both processes contribute to maintaining the star's internal thermal pressure.
How does contracting a protostar convert gravitational energy into thermal energy?
Sliding friction tends to convert kinetic energy into thermal energy, thermal energy being heat, kinetic energy being movement.
What slow down the contracting of a star forming cloud when it makes a protostar?
trapping of thermal energy inside the protostar
What two forces are within a protostar?
Gravitational force - which pulls matter towards the center of the protostar and is responsible for its contraction. Thermal pressure - which is generated by the heat and pressure within the protostar's core and pushes outward to counteract the gravitational force.
A newly formed protostar will radiate primarily at which wavelength?
A newly formed protostar will radiate primarily in the infrared wavelength range. This is because the protostar is still in the process of contracting and heating up, emitting energy as thermal radiation at longer wavelengths as it evolves towards becoming a main sequence star.
What is the gravitational potential energy of a contracting interstellar cloud?
The gravitational potential energy of a contracting interstellar cloud increases as the cloud collapses inward due to gravity. This potential energy is converted into other forms of energy, such as kinetic energy and thermal energy, as the cloud contracts and heats up, eventually leading to the formation of a star.
Why does a protostar heat up internally as it contracts?
A protostar heats up internally as it contracts due to the gravitational potential energy being converted into thermal energy. The collapse of the gas cloud causes an increase in density and pressure, leading to a rise in temperature at the core. This process eventually triggers nuclear fusion and marks the start of a star's life cycle.

Why does heat build up more rapidly in a massive protostar than in a less massive one?
A protostar starts forming when the gas particles start getting attracted towards one another with gravity. When they cannot be bound any closer the gravitational energy is transformed into thermal energy. With more massive protostars there is also more gravity available to become thermal energy.
How does heat build up in a protostar?
What a nice question. Gravity is a major force, and in so acting, it brings the various atoms and molecules closer together. This necessarily includes their state of energy - if an atom had a certain kinetic energy, then even when compressed with similar, one would now have a higher density of energy within the new smaller volume.
How do you convert Mass into thermal energy?
You generally need a catalyst or a mechanism to convert the energy. For example to convert fuel (a mass) into thermal energy, oxidizer and a spark are needed.
