• 1.000 N/m²

• 1.500 N/m²

• 8.500 N/m²

• 10.000 N/m²

Hubungan tekanan yang tepat dari gambar adalah

• $\rho_A>\rho_B>\rho_C=\rho_D<\rho_E$

• $\rho_A>\rho_B=\rho_C=\rho_D>\rho_E$

• $\rho_A=\rho_B>\rho_C=\rho_D<\rho_E$

• $\rho_A=\rho_B=\rho_C=\rho_D=\rho_E$

What law combines all 3 factors (pressure, temperature, and volume)

Apakah hukum yang menggabungkan ketiga-tiga faktor (tekanan, suhu, dan isipadu)

• Combined Gas Law / Hukum Gas Gabungan

• Charle's Law / Hukum Charle

• Boyle's Law / Hukum Boyle

• Pressure Law / Hukum tekanan

Boyle's law states that:

• Equal amounts of gases occupy the same volume at constant temperature and pressure.

• The volume of a fixed amount of gas is inversely proportional to its pressure at constant temperature.

• The volume of a fixed amount of gas is directly proportional to its temperature in Kelvin at constant pressure.

• The total pressure of a mixture of gases is the simple sum of the partial pressure of all of the gaseous compounds.

• The rates of effusion of gases are inversely proportional to the square roots of their molar masses.

• move randomly and freely

  bergerak secara rawak dan bebas.

• move at the same velocity

  bergerak pada halaju yang sama

• collide with one another in elastic collisions and with the walls of the container .

  berlanggar antara satu sama lain dengan perlanggaran kenyal dan dengan dinding bekas

• collides with the wall of the container produces change of momentum

  berlanggar dengan dinding bekas menghasilkan perubahan momentum.
