A gas has a pressure of 150 kPa at a volume of 6 m3. Calculate the volume of the same mass of gas at a pressure of 425 kPa

V2 = 2.12 m³

Explanation:

Given the following data;

Original pressure, P1 = 150 kPa

New pressure, P2 = 425 kPa

Original volume, V1 = 6 m³

To find the new volume V2, we would use Boyles' law.

Boyles states that when the temperature of an ideal gas is kept constant, the pressure of the gas is inversely proportional to the volume occupied by the gas.

Mathematically, Boyles law is given by;

Substituting into the equation, we have;

Therefore, the new volume of the mass of gas is 2.12 cubic metre.

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
