How does an aneroid barometer measure atmospheric pressure?
A barometer is an instrument used to measure atmospheric pressure. It can measure the pressure exerted by the atmosphere by using water, air, or mercury.An aneroid barometer is a barometer which measures pressure without using fluids!An aneroid barometer is somewhat different and uses a sealed chamber upon which the fluctuating atmospheric pressure acts. Through mechanical means a pointer is moved on a calibrated scale.
What are unilateral coercive measures?
Unilateral coercive measures, also known as sanctions, are actions taken by a country or group of countries to put pressure on another country in order to change its behavior or policies. These measures can include trade restrictions, financial sanctions, arms embargoes, or diplomatic isolation. They are imposed without the approval or consensus of international bodies such as the United Nations.
What is capillary reaction?
Usually called 'capillary attraction' or 'capillary action' it refers to the way very thin tubes can draw water up themselves without any external changes in pressure or without suction being applied.
What conditions does physical change occur in materials?
Physical changes in materials occur when the material undergoes a change in its physical properties without any change in its chemical composition. Examples of conditions that can cause physical changes include changes in temperature, pressure, or exposure to light or electricity. Physical changes can include changes in state (such as melting or freezing), changes in shape or size, or changes in properties (such as conductivity or solubility).
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.

What is PSI standing for?
PSI stands for Pounds per Square Inch. it measures the pressure inide an object. the pressure can come from boilding liquid in a metal conainer or compressed air in a ballon without popping.
What clef this instrument play in?
Impossible to say without knowing which instrument.
What are the advantages and disadvantages of pyrometers?
A pyrometer is a temperature measuring instrument that measures the temperature without making contact. The disadvantage is that the object must be hot enough to radiate visibly. The advantage is has a poor response time.
How does the candy thermometer?

The substance which changes from solid to vapour state at normal atmospheric pressure without being liquified is?
One substance that does that is carbon dioxide.
