What is the force that happens when matter is pushed or squeezed?
Pressure, usually reported as atmospheres.
Indicate the frequency level of a sound?
Frequency is usually not measured in "levels" (though the sound pressure or volume is) Frequency is measured in Hz (Hertz) or vibrations per second. Sound pressure is measured in Decibels
What is the unit for measuring the intensity of a sound?
Loudness N is measured in in sones.Loudness Level NL is measured in phons.Sound pressure level is measured in dBSPL, where the reference level of 0 dBSPL is the threshold of hearing.The ear drums and the microphones are only sensitve to the sound pressure. We measure the sound pressure with a sound level meter.Loudness is affected by sound pressure, frequency and its bandwidth, and duration (time).Usually sound is measured in Decibels.
What kind of distances are measured in millimeters?
Usually small distances. You may get rainfall measured in mm.
How is gunpowder measured?
Gunpowder is usually measured in grain weight. 7,000 grains = 1 pound
Why is the boiling point of a pure liquid usually reported along with the pressure at which the boiling point was measured?
Because the pressure could affect the temperature at which the water boils
Why are boiling points of liquids usually reported along with the pressure at which the boiling point was measured?
Melting points of pure solids are reported without including the pressure. This is because it is assumed that standard laboratory conditions of 1 BAR, or 25 degrees Celsius were used.
Is low blood pressure the same as low iron?
No. Blood pressure is an actual pressure; it's usually measured in mmHg, but it COULD be measured in kilopascals or pounds per square inch. "Low iron" generally refers to the measurement of a protein called ferritin, and is usually measured in ng/mL.
What is the force that happens when matter is pushed or squeezed?
Pressure, usually reported as atmospheres.
What is low vapor pressure?
Vapor pressure refers to the force exerted by gaseous molecules of a liquid. Usually this is measured in a closed system. For example, in a water bottle some H2O molecules are able to move from liquid to gas phase at room temperature. The molecules that do this create vapor pressure. Low vapor pressure is usually observed in substances that have a low boiling point or if it is being held at a low temperature.
Indicate the frequency level of a sound?
Frequency is usually not measured in "levels" (though the sound pressure or volume is) Frequency is measured in Hz (Hertz) or vibrations per second. Sound pressure is measured in Decibels
What is measured in inches of mercury?
Those are (somewhat outdated) pressure units.
What gauge measures both vacuum and pressure?
Gauge pressure usually refers to the pressure difference between ambient, atmospheric pressure and the pressure in a vessel or line. A gauge pressure of zero would mean that the vessel or line was at atmospheric pressure. Normally the pressures of interest are ABOVE atmospheric so the gauge pressure is positive. Vacuum gauge pressure measures how far BELOW atmospheric pressure a vessel or line is. As such vacuum gauge pressure may be measured as a negative number - or for convenience it may be reported as a positive number with the caveat that it is "vacuum gauge pressure", meaning that the reported pressure is how far atmospheric pressure is above the pressure in the vessel or line.
What is the unit for measuring the relative intensity or loudness of sound?
Loudness N is measured in in sones.Loudness level LN is measured in in phons.Sound pressure level is measured in dBSPL, where the reference level of 0 dBSPL is the threshold of hearing.The ear drums and the microphones are only sensitve to the sound pressure.We measure the sound pressure with a sound level meter.Loudness is affected by sound pressure, frequency and its bandwidth, and duration (time).Usually sound is measured in Decibels.
Air pressure is the weight of air pressing down on the earth it is measured by a barometer what kind of weather does high pressure usually bring?
humidity

Would you consider atmospheric pressure when finding the pressure of a liquid in a closed container?
pressure is usually measured relative to atmospheric this is called gauge pressure. if you compare against absolute zero pressure (vacuum) this is called absolute pressure.
