الكثافة تعتمد على الmass و الvolume بمعنى انه فى السؤال يجب ان يذكر ان الكتلة ثابتة و فى حالة ان الكتلة ثابتة فالكثافة سوف تقل الى النصف

Halved
since Vol.=Mass/Denisty

decreases to 1/2



the density is not a physical property for gases because gases are compressible

i think if the volume is doubled at a constant temperature the pressure would would be halved and since:
density = 3p/v squared the density would decrease to half

density of the material is a physical prop, and constant for the single material so it is a distingiushing properity.
it might be affected by temp in gases
and since temp is constant density will keep constant

BUT

you will tell me the vol is doubled you so pressure is decreased into half.

and since P = (1/3) P v2
v here is velocity not vol as mentioned before
since temp is constant velocity will be const.

from relation the result is density will decrease since p is decreased

BUT

so density will decreases into HALF TOOOOOO

welcome in gases world guys


so we can solve it from beginning density = mlv so if volume is doubled density will decrease into Half

but you need the explaination to understand

thanks to you

keep constant
you say temp cons
then when volume doubled the mass will be change

جزاك الله خيرا
وبارك الله فيك

decreased to half
because pressure inversily proportional to volume and directly proportional to denisty at constant temp.
so volume is inversily proportional to denisty at constant pressure and temp

انتم عارفين اساسا يعني ايه physical property for matter
يعني انها مبتتاثرش غير بحاجتين
Temperature and kind of material
و الاتنين هنا ثابتين يبقي الdensity constant
و بالمنطق كده لو انت مثبت الحرارة الطريقة الوحيدة انك تزود الvol انك تزود الmass معاها
علي فكرة مفيش حاجة اسمها direct w inverse relation in physical property of matter

بس السؤال غريب اصلا لانه محددش احنا بنتكلم علي gas or solid or liquid
Bec. In gases density will dec. to half

keep constant
لما تزود الحجم الكتلة لازم تزيد معاها وتفضل الكثافة ثابتة بس كده يا سيدى

ممكن تزود الحجم والكتلة ثابتة بالنسبة للغازات .

اخى الكريم انت تقول تغير الحجم يغير الكتلة هذا خطأ لان الغاز يشغل اى حجم وتغير ظروفه لا يغير كتلته الا فى حالة تسرب او اضافه
وشكرا

Characteristic density depends on the type of material when the temperature to and clarify important wood density 600 increased the size of the segment increased mass quotient remains steady

To say an inverse relationship must install mass and lack of Hajj this is impossible because the mass increase over her size
