Why is temperature the measure of average energy of motion of all the particles within a substance?
Temperature is the measure of average energy of motion of particles within a substance because temperature reflects the amount of kinetic energy present in the particles. As particles move faster, they have higher kinetic energy. By measuring the average kinetic energy of particles, temperature provides a standardized way to compare the thermal energy of different substances.
Who discovered Avogadro's number and what is its significance in chemistry?
Avogadro's number was discovered by Italian scientist Amedeo Avogadro in the early 19th century. It represents the number of particles in one mole of a substance, which is a fundamental concept in chemistry for measuring and relating the amount of substances in chemical reactions.
What is the substance that a thermometer is actually measuring when it is placed in it?
A thermometer measures the temperature of a substance by detecting the average kinetic energy of its molecules.
Are particles matter and how do they contribute to the composition of substances?
Yes, particles are matter. They are tiny units that make up all substances. Particles contribute to the composition of substances by coming together to form the structure and properties of the substance.
What can be learned from measuring a temperature change in a substance?
Measuring a temperature change in a substance can provide information about the heat energy being transferred into or out of the substance. This can help in understanding the substance's properties, such as its specific heat capacity or phase changes. It can also be used to monitor chemical reactions, physical changes, or to determine the efficiency of heating or cooling processes.
How much is 7.6Lt in kg?
To convert liters to kilograms, you need to know the density of the substance you are measuring. The conversion factor will vary depending on what you are measuring, as different substances have different densities.
When you are measuring volume what are you actually measuring?
space occupied by a substance.

What element are you measuring the concentration of ions of when measuring the pH of a substance?
You are measuring the concentration of the cation of hydrogen. Hence the name 'power of Hydrogen' -> pH
Can density be used as identification for substances in lab?
Yes, density can be used as a useful property for identifying substances in lab experiments. By measuring the density of a substance and comparing it to known values, scientists can help determine the identity of an unknown substance.
What are two reasons why density is a useful property identifying substances?
Density can tell you how "pure" a substance is. Since each substance has a specific density in its "pure" state, having no other substances in its composition, by measuring it density you can tell how pure the mineral or substance is, 99.9% pure gold.

What does 45 mL equal in pounds?
depends on what substance you are measuring
How does a thermometer help when comparing the energies of particles?
A thermometer measures the amount of thermal energy a material has. This thermal energy is related to the vibrational and rotational energy the particles in the material have. By using the thermometer to measure the temperature of a material you are, in effect, measuring the amount of energy the particles of that material have.
Fathom is the unit used for measuring?
Fathom is the unit for measuring height of a mountain depth of water hardness of a substance velocity of an object none above
How would you measure the pH of a colored substance?
