0.67 atmospheres
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
Usually we use a temperature of 20 °C and an absolute pressure of 101.325 kPa for 1 atmosphere.
Assuming the amount of gas remains constant, we can use the ideal gas law to calculate the final absolute pressure. The initial pressure (P1) is 200 kPa and the final volume (V2) is 250 cm3. The initial temperature (T1) is 40 degrees Celsius or 313.15 Kelvin, and the final temperature (T2) is 20 degrees Celsius or 293.15 Kelvin. Using the equation (P1 * V1) / T1 = (P2 * V2) / T2, we can solve for the final absolute pressure (P2), which is approximately 400 kPa.
I ran your question passed my trusty computer based widget and the answer it gave was just above 150 mm of Hg
Bar is a unit of pressure. 20 bar is approximately 20 times the atmospheric pressure.
10 cubic inches
twenty inches of mercury

At standard temperature and pressure, there aren't 20 liquid elements. The only one would be mercury and bromine. If you change the temperature and pressure appropriately, any of the elements could conceivable be a liquid.
The physical state of Mercury is a LIQUID at 20oC . It is one of only two elements that are liquid at Standard Temperature and Pressure. The other being Bromine.
There are a few ways to define "opposite." It could be -20 or 1/20. The absolute value of 20 is 20.
I beileive that the absolute value of -20 is 20 because if you do the absolute value it seems to turn out as the positive form of itself in other words, if you take -10 and find the absolute value, it is 10 and if you take 60 and find the absolute value it equals 60
