Front

What is the life cycle of an average star?

Back

The life cycle of an average star follows this sequence: protostar > main sequence > red giant > white dwarf.

Front

What determines the life cycle path a star will take?

Back

The mass of the star determines its life cycle path.

Front

Which star is the coldest?

Back

The coldest star is a Red Star.

Front

What happens to the density of water or air when its temperature increases?

Back

When the temperature of water or air increases, it becomes less dense and rises.

Front

What are the primary elements that most stars are made of?

Back

Most stars are primarily made of Hydrogen and Helium.

Front

Define a protostar.

Back

A protostar is a dense region within a nebula that begins to collapse under its own gravity, leading to the formation of a star.

Front

What is a main sequence star?

Back

A main sequence star is a star that is in the stable phase of its life cycle, where it fuses hydrogen into helium in its core.

Front

What is a red giant?

Back

A red giant is a late stage in a star's life cycle where it has expanded and cooled after exhausting the hydrogen in its core.

Front

What is a white dwarf?

Back

A white dwarf is the remnant core of a star that has exhausted its nuclear fuel and shed its outer layers.

Front

How does the mass of a star affect its life cycle?

Back

The mass of a star influences its temperature, luminosity, and the duration of each phase in its life cycle.
