1- Gas Giants – PTE – Speaking – Re tell Lecture – GrowSkills – PTESkills.net
Transcript:
So there are two theories for how the gas giants formed. One is the same theory I showed you just now core accretion, right. And the other is called disk instability and one of our colleagues at DTM has done a lot of work on that and so it’s unclear exactly how they formed but you’re right what we’re trying to do the reason we’re trying to get the higher and higher pressure in the lab is because we are trying to understand more about the pressure inside the gas giants. It’s thought that the gas giants also have a metallic core, but maybe the metallic core not made of iron. Hydrogen, for example becomes metallic at a certain pressure. So it’s very possible that the insides of these planets could have metallic cores, could have hydrogen cores, could have rocky portions we’re not sure. But the higher pressure we can get in the lab, the closer we can get understanding the interiors of the gas giants and the exoplanet that are so big.

So there are two theories for how the gas giants formed.
One is the same theory I showed you just now core accretion, right.
لذلك هناك نظريتان حول كيفية تشكل عمالقة الغاز.
إحداها هي نفس النظرية التي عرضتها لك الآن وهي التراكم الأساسي، أليس كذلك.
And the other is called disk instability and one of our colleagues at DTM has done a lot of work on that and so it’s unclear exactly how they formed but you’re right what we’re trying to do the reason we’re trying to get the higher and higher pressure in the lab is because we are trying to understand more about the pressure inside the gas giants.
والآخر يسمى عدم استقرار القرص وقد قام أحد زملائنا في DTM بالكثير من العمل على ذلك ولذلك فمن غير الواضح بالضبط كيف تشكلوا ولكنك على حق فيما نحاول القيام به والسب ب الذي نحاول الحصول عليه إن الضغط المتزايد في المختبر هو لأننا نحاول فهم المزيد عن الضغط داخل عمالقة الغاز.
It’s thought that the gas giants also have a metallic core, but maybe the metallic core not made of iron.
ويُعتقد أن الكواكب الغازية العملاقة تمتلك أيضًا قلبًا ،معدنيًا، ولكن ربما لا يكون القلب المعدني مصنوعًا من الحديد.
فالهيدروجين، على سبيل المثال، يصبح
معدنًا عند ضغط معين.
Hydrogen, for example becomes metallic at a certain pressure.
So it’s very possible that the insides of these planets could have metallic cores, could have hydrogen cores, could have rocky portions we’re not sure.
لذا، فمن المحتمل جدًا أن يكون للأجزاء الداخلية من هذه الكواكب نوى معدنية، أو يمكن أن تحتوي على نوى هيدروجينية، أو يمكن أن تحتوي على أجزاء صخرية، لسنا متأكدين من ذل
But the higher pressure we can get in the lab, the closer we can get understanding the interiors of the gas giants and the exoplanet that are so big.
لكن كلما زاد الضغط الذي يمكننا الحصول عليه في المختبر ، كلما اقتربنا من فهم الأجزاء الداخلية من عمالقة الغاز والكواكب الخارجية الكبيرة جدًا.
