Yes, but only in solids and liquids in special situations. Surface tension can allow liquids in very narrow channels to be placed in tension. This is believed to explain how some trees can pull sap hundreds of feet above the ground.
P1V1=P2V2
Since volume is NEVER negative, that would mean your initial absolute pressure would have to be negative, which here on Earth, or even in the void of space, is NEVER the case. So PSIA can NEVER be negative, and PSIG can be considered HIGH/HARD or LOW/SOFT vacuum(negative PSIG) in reference to a relative scale between 0 PSIA and 14.7 PSIA.
Yes it can - if the pressure is less than atmospheric pressure.
As vacuum pressure.
The maximum negative pressure in isolated system is negative ATM. ATM is the pressure created by air molecules and it is 1.01325*10^5 Pa. So a negative pressure of 1 ATM means absolute vacuum.
Absolute pressure is simply the addition of the observed gage pressure plus the value of the local atmospheric pressure.
No, the absolute pressure in a liquid of constant density would not double in this situation. This is because the atmospheric pressure is an independent variable, so it will keep the absolute pressure from doubling.
pressure
The Kelvin Scale is based on absolute zero which means it will never go negative. For example, in the ideal gas law, finding the pressure using Celsius(with a temp -12C) the pressure can be -23atm which is impossible.
No. "Absolute" means non-negative.
The maximum negative pressure in isolated system is negative ATM. ATM is the pressure created by air molecules and it is 1.01325*10^5 Pa. So a negative pressure of 1 ATM means absolute vacuum.
absolute pressure
Bourdon's tube pressure gauge cannot be used to measure negative pressure. This is because absolute pressure must be measured and the Bourdon gauge only indicates the gauge pressure.
An absolute value can not be negative.
NO, absolute value is always non-negative.
If the absolute value of the negative is bigger than that of the positive, then the answer is negative. If the absolute value of the negative is the same, then zero. If the absolute value of the negative is smaller, then positive. Absolute value is the value ignoring the sign.
The opposite is: negative (the absolute value of negative 30).
Absolute values are never negative. The opposite, or negative, or additive inverse, of a negative number is the number's absolute value; a non-negative number is its own absolute value. The absolute values of 7 and -5, are, respectively, 7 and 5.
When the absolute value of the positive integer is smaller than the absolute value of the negative one.
The absolute value becomes negative.
No, an absolute value must be non-negative.
