Law of Conservation of Energy.
Star formation begins with the gravitational collapse of a dense region within a molecular cloud. As the cloud collapses, it heats up and forms a protostar. The protostar continues to accumulate mass and eventually ignites nuclear fusion in its core, becoming a main-sequence star.
The Sun heats up the Earth At least, mostly It heats up the molecules in the air, which also explains why it's colder the higher you are- there are less air molecules for the Sun to heat up
The visible radiation produced by new stars within a molecular cloud is absorbed and scattered by the surrounding gas and dust in the cloud. This can cause the radiation to be reddened, blocked, and scattered in different directions, making it more difficult to detect the stars visually.
A protostar is the second phase of a star's life because it forms after a molecular cloud collapses under its own gravity, leading to the accumulation of material in a dense core. This core heats up as it contracts, eventually reaching temperatures and pressures sufficient to initiate nuclear fusion. The protostar stage is characterized by the gathering of mass and the development of a surrounding disk of gas and dust, which can eventually form planets. Once nuclear fusion begins in the core, the protostar evolves into a main sequence star.
Thunder is a physical phenomenon that occurs when lightning heats the air rapidly, causing it to expand and create a shockwave. It is not a chemical change because the composition of the air molecules remains the same before and after the thunder occurs.
Clouds heat up due to the process of adiabatic compression as air rises within a cloud. As the air rises, it cools due to expansion but warms as it descends, leading to an overall increase in temperature. This is governed by the ideal gas law and the principles of thermodynamics.
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.
A spinning cloud of gases typically refers to a phenomenon in space where gases, such as hydrogen and helium, are coalescing due to gravitational forces. This process can lead to the formation of stars or planets as the spinning cloud of gases slowly collapses and heats up.
The main source of energy during this stage is gravitational potential energy, as gas in the interstellar cloud collapses under gravity to form a protostar. The energy released from this gravitational collapse heats up the material and initiates the process of star formation.
Stars form in the universe through the process of gravitational collapse of gas and dust within interstellar clouds. As the cloud collapses, it heats up and forms a protostar, which eventually ignites nuclear fusion in its core, becoming a full-fledged star.
When a large cloud of dust and gas begins to collapse due to gravity, it can undergo a process called protostar formation. As the cloud collapses, it heats up and starts spinning, eventually forming a dense core at its center. This core will continue to accumulate material and eventually become hot and dense enough to initiate nuclear fusion, becoming a star.

Stars are formed through a series of steps starting with the gravitational collapse of a cloud of gas and dust. As the cloud collapses, it heats up and forms a protostar. The protostar continues to contract and heat up until the core reaches temperatures high enough for nuclear fusion to begin. Once nuclear fusion ignites in the core, the star is born and begins to shine brightly.
The sea gets hot by the sun and the heats the water making evaporation and then making a condensed cloud then the cloud moves and the cloud is getting very heavy so it rains and the goes back inti the sea and rivers and repeats.
A star forms from a cloud of gas and dust that collapses under the force of gravity. As the cloud becomes more compressed it heats up, eventually becoming hot enough to fuse hydrogen.

Water both heats up and cools down at a slower rate than land.
