Yes, stars generally get hotter as they age due to the process of nuclear fusion in their cores, which increases the temperature and brightness of the star over time.
The age of a star cluster can be determined by looking at the mass of stars at the turnoff point. If the stars at the turnoff point have a mass of 3 times the mass of the Sun (3m), then the age of the cluster is estimated to be around 1 billion years.
No, in Celsius temperature scale, lower temperatures are colder and higher temperatures are hotter.
72°F is hotter than 64°F.
The top of the oven is usually hotter than the bottom.
The top of the oven is typically hotter than the bottom.
stars are hotter
Blue stars are the hottest, because they are newborn stars. Yellow stars are medium age stars, like our sun, and are right in the middle. Red stars are the oldest, and will explode very soon, so those are the coolest (but still pretty hot; hotter than your oven!).
Its colour. White stars are hotter than blue stars which are hotter than yellow which are hotter than orange, which are hotter than red.
Technically Blue stars are hotter but from your options, white stars are hotter.
White Dwarves and Blue giants are both hotter than Red giant stars.
Stars can be both cooler and brighter or hotter and dimmer than the Sun, depending on their size and age. Generally, larger and younger stars are hotter and brighter than the Sun, while smaller and older stars can be cooler and dimmer.
yes
Hotter.
blue stars are hotter
As they get hotter, they usually get brighter.
False. Blue giants(or hypergiants) are hotter than Red giant stars. White dwarves are also hotter but they are smaller than blue giants. (As is implied by the name.)
The sun is hotter than red stars but cooler than blue stars,
