DB Star Life

Front

What was formed by the Big Bang according to the theory?

Back

Hydrogen, Helium and Lithium.

Front

What happens to water or air when its temperature increases?

Back

It will be less dense and rise.

Front

What is the correct order of an average star's life cycle?

Back

protostar > main sequence > red giant > white dwarf.

Front

In which stage of a star's life cycle does helium fuse into heavier elements?

Back

Red Giant.

Front

What is a method of heat transfer?

Back

Conduction.

Front

What is a protostar?

Back

A protostar is a dense region in a molecular cloud where gas and dust are collapsing under gravity to form a new star.

Front

What is the main sequence phase of a star?

Back

The main sequence is the longest phase in a star's life cycle where it fuses hydrogen into helium in its core.

Front

What occurs during the red giant phase of a star?

Back

During the red giant phase, a star expands and cools after exhausting hydrogen in its core, leading to helium fusion.

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

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials.
