Why is the average kinetic energy of the particles of a substance?
As stated in the kinetic-molecular theory,
the temperature of a substance
is related to the average kinetic energy of the particles of that substance. When a substance is heated, some of the absorbed energy is stored within the particles, while some of the energy increases the motion of the particles.
How does a thermometer measure kinetic energy?
As molecules of air move
, they hit the walls of a thermometer with kinetic energy. Each collision between an air molecule and the wall of the thermometer results in a transfer of thermal energy from the air to molecules in the thermometer.
What is used to measure the average kinetic energy of all gas particles?
Instead,
temperature
can be used as a measure of the average kinetic energy of all the molecules in the gas. As the gas molecules gain energy and move faster, the temperature goes up.

What refers to the measurement of the average kinetic energy of the molecules and represents the motion of molecules?
In chemistry, we define
the temperature of a
substance as the average kinetic energy of all the atoms or molecules of that substance.
Which of the following is a measure of the average kinetic energy of the particles in a sample of matter *?
The temperature of a substance
is a measure of the average kinetic energy of the particles.
Which instrument is used to measure changes in volume of substances?
Answer:

is used to measure change in volume of a substance.
Is a measurement of the average kinetic energy of the microscopic particles that make up an object?
Temperature
– a measure of the average kinetic energy of the particles in an object.
What does a sling psychrometer measure?
A sling psychrometer can be used to find
relative humidity
, which is expressed as a percentage. It is computed by multiplying the amount of moisture in the air at a given temperature, dividing by the maxi- mum amount of moisture the air could contain at that same temperature, and then multiplying the quotient by 100.
What average energy of particles does temperature measure?
Temperature is a measure of the
average kinetic energy
of the particles in a substance. It is the kinetic energy of a typical particle.
Which device used for measuring temperature?
One of the most common devices for measuring temperature is
the glass thermometer
. This consists of a glass tube filled with mercury or some other liquid, which acts as the working fluid. Temperature increase causes the fluid to expand, so the temperature can be determined by measuring the volume of the fluid.
What does the average kinetic energy of the particles in solids liquids and gases measure?
The temperature of a
substance is a measure of the average kinetic energy of the particles.
What is average kinetic energy?
For a gas molecule, the average kinetic energy is defined as
the product of the half of the mass of each gas molecule and the square of RMS speed.
What is the average kinetic energy of a molecule?
The average kinetic energy of the molecules is
5.66 × 10−21 J
. According to Kinetic Molecular Theory, the average kinetic energy of gas molecules is a function only of temperature.
How does an average kinetic energy of a gas molecule depend on the absolute?
Explanation: The average kinetic energy of gas molecules is
directly proportional to absolute temperature only
; this implies that all molecular motion ceases if the temperature is reduced to absolute zero.
What are the 3 measuring instruments?
- Angle Locator.
- Bubble Inclinometer.
- Calipers.
- Compass.
- Level.
- Pressure Gauge.
- Protractor.
- Ruler.
What are the 3 types of measurement?
The three standard systems of measurements are
the International System of Units (SI) units, the British Imperial System, and the US Customary System
. Of these, the International System of Units(SI) units are prominently used.
Which is the most accurate measuring instrument?
Screw gauge
has minimum least count of 0.001cm. Hence, it is most precise instrument.
What are mechanical instruments?
mechanical instrument in British English
noun.
a musical instrument
, such as a barrel organ or music box, that plays a preselected piece of music by mechanical means. Collins English Dictionary.
What are measurement instruments in research?
The instruments are used to measure or collect data on a variety of variables ranging from physical functioning to psychosocial wellbeing. Types of measurement tools include
scales, indexes, surveys, interviews, and informal observations
.
Which instrument is used to measure sound underwater?
A hydrophone
is used to listen to underwater sounds.
Which instrument is used to measure the scattering of light by particles suspended in a liquid?
Answer:
Nephetometer
is used to measure the scattering of light by particles suspended in a liquid .
What refers to the measurement of the average kinetic energy of the molecules and represents the motion of molecules Brainly?
Temperature
is a measure of the average amount of kinetic energy possessed by the particles in a sample of matter. The more the particles vibrate, translate and rotate, the greater the temperature of the object.
What are the 5 types of measurements?
Types of data measurement scales:
nominal, ordinal, interval, and ratio
.
What is used to measure the volume of the substance?
The volume of a substance can be measured in
volumetric glassware
, such as the volumetric flask and the graduated cylinder. Density indicates how much of a substance occupies a specific volume at a defined temperature and pressure. The density of a substance can be used to define the substance.
Is temperature a measure of average kinetic energy?
Temperature is a measure of
the average kinetic energy of the particles in an object
. When temperature increases, the motion of these particles also increases. … Thermal energy is the total energy an object has due to the internal motions of its particles.
Which of the following is a measure of the average kinetic energy of the particles in a sample of matter quizlet?
Temperature
is the measure of the average kinetic energy of the particles in an object.
Is a measure of the average?
Often “average” refers to
the arithmetic mean
, the sum of the numbers divided by how many numbers are being averaged. In statistics, mean, median, and mode are all known as measures of central tendency, and in colloquial usage any of these might be called an average value.
Which sample has particles with the lowest average kinetic energy?
Particles at the same temperature have the same average kinetic energy, so
argon and nitrogen
, which are at 20°C , are the gases with the lowest average kinetic energy. Nitrogen and helium, at 100°C , have the highest average kinetic energy because they have the highest temperature.
