B. The average speed of the nitrogen molecules is the same as the average speed of the argon molecules.
The given parameters;

mass of the nitrogen = 14 g
mass of the argon = 20 g

The density of an object is defined as mass per unit volume . The gas with greater mass will have the greater density.
The average speed of the gases decreases with increase in mass . The gas with smaller mass will have the greatest speed.
The average kinetic energy of the gases increases with increase in speed .
The number of moles , and volume of gases is different.
Thus, the only incorrect statement in the given options is B .
"The average speed of the nitrogen molecules is the same as the average speed of the argon molecules".

The false statement is B: "The average speed of the nitrogen molecules is the same as the average speed of the argon molecules," because nitrogen, being lighter, moves faster than argon at the same temperature. All other statements are true based on properties of gases at the same temperature and pressure. Therefore, the key takeaway is relating molecular mass to speed in gases.

Jawaban: Diketahui:1. 4 tahun yang lalu, umur Nabila = 2 × umur Masyitoh saat itu2. Tahun ini, umur Nabila + umur Masyitoh = 20 tahun---Misalkan:Umur Nabila tahun ini = NUmur Masyitoh tahun ini = M---Dari soal:4 tahun yang lalu:Umur Nabila = N − 4Umur Masyitoh = M − 4→ N − 4 = 2 × (M − 4)Tahun ini:N + M = 20--- Substitusi dan Penyelesaian:Dari N − 4 = 2(M − 4), kita uraikan:N − 4 = 2M − 8N = 2M − 4 → (Persamaan 1)Dari N + M = 20 → (Persamaan 2)Sekarang, ganti nilai N di persamaan 2:(2M − 4) + M = 203M − 4 = 203M = 24M = 8Masukkan nilai M ke persamaan 1:N = 2M − 4N = 2(8) − 4 = 16 − 4 = 12---✅ Jawaban:Umur Nabila tahun ini adalah 12 tahunBantu kasih like nya ya apabila jawaban ini membantu.
