What is an instrument that measures hot and cold?
A thermometer is an instrument that measures hot and cold temperatures. It typically uses a liquid, such as mercury or alcohol, to gauge the level of heat or coldness in its surroundings.
Difference between pressure gauge and manometer?
A pressure gauge measures pressure in a system relative to atmospheric pressure, displaying the reading in units such as psi or bar. A manometer measures pressure by balancing the weight of a liquid with the pressure being measured, often displaying pressure differentials in terms of inches or millimeters of the liquid column. In summary, a pressure gauge gives absolute pressure readings, while a manometer measures pressure differentials.
How can you make a liquid boil without raising its temperature?
Reduce the surrounding pressure. Lowering the pressure on a liquid reduces its boiling point, causing it to boil at a lower temperature.
What instrument measures the specific gravity of a liquid?
A hydrometer is commonly used to measure the specific gravity of a liquid. It is a glass or plastic tube with a weighted bottom that floats in the liquid, and the specific gravity is read at the level of the liquid where the hydrometer surface intersects.
What measures the hear from expanding and contracting liquid or coils?
A pressure relief valve or expansion tank can help control the pressure in heating systems to prevent expansion and contraction of liquid or coils. The relief valve releases excess pressure, while the expansion tank absorbs the extra volume of liquid as it expands.
Instrument that measures air pressure without using a liquid?
aneroid barometer
What is the instrument that measures changes in air pressure without using a liquid?
An aneroid barometer is an instrument that measures changes in air pressure without using a liquid. It uses a flexible metal box called an aneroid cell that expands and contracts with changes in pressure, which is then translated into a measurement on a dial.
What instrument measures the capacity of a liquid?
Beaker
What is an atmometer?
An atmometer is an instrument which measures the rate of evaporation of a liquid.
Is manometer used to measure the pressure of liquid?
yes,manometer is an instrument . It is used to measure pressure of liquid.
What instrument measures the pressure in an enclosed container of gas?
A manometer is used to measure pressure in an enclosed container of gas. It typically consists of a U-shaped tube filled with liquid that reacts to changes in pressure inside the container. The liquid level in the arm of the manometer connected to the container will rise or fall based on the pressure, providing a measurement of the gas pressure.
What instrument measures the tilt of a surface - one that has an air bubble in a liquid?
A spirit level.
What is an instrument that measures hot and cold?
A thermometer is an instrument that measures hot and cold temperatures. It typically uses a liquid, such as mercury or alcohol, to gauge the level of heat or coldness in its surroundings.
What instrument measures the density of milk?
Lactometerlactometer
What instrument measures the volume of a square solid?
A ruler no a better way is by dropping the cube in a liquid containg beaker displaced liquid will give you the volume
How can the boiling point of a liquid be raised without adding soluble impurity?
The boiling point of a liquid is the temperature at which the vapor pressure of the liquid equals the atmospheric pressure, or the pressure above the liquid. So, to increase the boiling point without adding a solute, one can increase the pressure above the liquid.
Is a instrument that keeps continuous record of air pressure?
A barometer is an instrument that keeps a continuous record of air pressure. It consists of a glass tube filled with mercury or other liquid that rises and falls based on changes in atmospheric pressure. The fluctuations in the liquid's height are used to determine changes in air pressure over time.
