The pH scale (not hP) is used to measure the acidity/basicity of an aqueous solution. It actually is a measure of the hydronium ion concentration. pH <7 is acidic; pH>7 is basic; pH=7 is neutral.
Any scale can be used; the absolute, rational, thermodynamic based scale is the Kelvin scale.
No. The Richter scale (since replaced by the Moment Magnitude scale) was used to measure earthquake intensity. The Fujita scale (now the Enhanced Fujita scale in the U.S.) is used to rate tornadoes.
An equal-arm balance.
it is used to measure the weight of an object
a spring scale
Richter scale
A seismograph is used to measure ground movement or vibrations on the Richter scale.
The scale used to measure the strength of an earthquake is called the Richter scale
There is no scale!!
A scale is used to measure a weight of an object
is there a scale used to measure the intensity of heat wave
A spring scale
No, nothing is used to measure the Richter scale. The Richter scale is used to measure the intensity of earthquakes.The Volcanic Explosivity Index (VEI) is used to provide a relative measure of the explosiveness of volcanic eruptions.
PAGASA used richter scale to measure the intensity of an earthquake
A spring scale is used to measure force or mass
A scale is used to measure things...I see you've tagged "tornadoes" so you may be referring to the Fugita Scale--which is used to measure the damage caused by a tornado.
In the United States, the Fahrenheit scale is commonly used to measure air temperature.
