20 cubic inches of gas with an absolute pressure of 5 psi is compressed until its pressure reaches 10 psi what is the new volume of gas?

B. 10 Cubic inches
The formula is:
po - original gas pressure
vo - original volume
pf - final gas pressure
vf - final volume
Po*Vo = Pf*Vf
or
5psi x 20 in3 = 10psi x Vf

Using Boyle's Law, we can calculate the new volume of gas:
(P1)(V1) = (P2)(V2).
Given: P1 = 5 psi, V1 = 20 cubic inches, P2 = 10 psi.
Solving for V2: (5)(20) = (10)(V2).
V2 = 10 cubic inches.

What is the absolute pressure at 20 inches of mercury?
The absolute pressure at 20 inches of mercury is approximately 10.3 psi (pounds per square inch). This is calculated by adding the atmospheric pressure (14.7 psi) to the gauge pressure or vacuum pressure (negative in this case) represented by the 20 inches of mercury column.
If a pressure of twenty pounds per square inch exists when the volume of the gas is 500 cubic inches what is the pressure when the gas is compressed to 400 cubic inches?
Using Boyle's Law (P1V1 = P2V2), we can find the new pressure. P1 = 20 psi, V1 = 500 in^3, V2 = 400 in^3. P2 = (P1 * V1) / V2 = (20 * 500) / 400 = 25 psi. Therefore, the pressure when the gas is compressed to 400 cubic inches will be 25 pounds per square inch.
The atmospheric pressure is given as 29.4 inches of mercury what is the corresponding pressure in mm Hg?
The atmospheric pressure of 29.97 inch of mercury (32 °F) is 761.238123 millimeter Hg (0 °C) or 1.001629 atm. Scroll down to related links and use the nice calculator "Conversion of pressure or stress units".
Difference between pressure gauge and manometer?
A pressure gauge measures pressure in a system relative to atmospheric pressure, displaying the reading in units such as psi or bar. A manometer measures pressure by balancing the weight of a liquid with the pressure being measured, often displaying pressure differentials in terms of inches or millimeters of the liquid column. In summary, a pressure gauge gives absolute pressure readings, while a manometer measures pressure differentials.

20 cubic inches of gas with an absolute pressure of 5 psi is compressed until it's pressure reaches 10 psi . What Is the new volume of the gas?
10 cubic inches
What is the absolute pressure at 20 inches of mercury?
The absolute pressure at 20 inches of mercury is approximately 10.3 psi (pounds per square inch). This is calculated by adding the atmospheric pressure (14.7 psi) to the gauge pressure or vacuum pressure (negative in this case) represented by the 20 inches of mercury column.
A pressure gauge reads57 psi The equivalent pressure in inches of mercury absolute is?
To convert psi to inches of mercury absolute, divide the psi value by 2.036. In this case, 57 psi divided by 2.036 is approximately 27.97 inches of mercury absolute.
If a pressure of twenty pounds per square inch exists when the volume of the gas is 500 cubic inches what is the pressure when the gas is compressed to 400 cubic inches?
Using Boyle's Law (P1V1 = P2V2), we can find the new pressure. P1 = 20 psi, V1 = 500 in^3, V2 = 400 in^3. P2 = (P1 * V1) / V2 = (20 * 500) / 400 = 25 psi. Therefore, the pressure when the gas is compressed to 400 cubic inches will be 25 pounds per square inch.

If the atmospheric pressure is 29.4 inches of mercury what is the corresponding pressure of mercury?
The atmospheric pressure of 29.4 inches of mercury is equivalent to 74.676 millimeters of mercury. This conversion is based on the standard ratio where 1 inch of mercury is equal to 25.4 millimeters of mercury.
What is absolute spread in a rolling mill?
Simply put, absolute spread in a rolling mill is the difference in the width of the stock we put in and the width of the finished piece. For instance, if a bar goes in and is rolled to reduce its thickness and it is 4 inches wide when it goes in and is 10 inches wide when it comes out, the absolute spread of the rolling mill in this operation is 6 inches. (The maximum output width, 10 inches, minus the input width, 4 inches, equals the absolute spread, 6 inches.)

What is the value of absolute vacuum?
Absolute vacuum refers to a theoretical state where there is a complete absence of matter, including particles and radiation. It is a state with zero pressure and zero energy. This concept is used in physics to establish a benchmark for comparing different pressure levels in a system.
