What do concentration and conductivity both have?
Both concentration and conductivity are measures of the amount of a substance present in a solution. Concentration refers to the amount of solute dissolved in a solvent, while conductivity measures the ability of a solution to conduct electricity, which is related to the presence of ions in the solution.
What are the factors that effects the conductivity of pencil lead?
The factors that affect the conductivity of pencil lead include the quality of the graphite in the lead, the hardness of the pencil lead, and any impurities present in the lead. Higher quality graphite and softer leads typically have higher conductivity, while impurities can decrease conductivity. Additionally, the pressure applied when writing or drawing with the pencil can also impact conductivity.
Does temperature depend on the amount of a substances?
The answer is no
What is a standardized amount?
a mole of a substances
What is electric conductivity intensive or extensive?
Electric conductivity is an intensive property because it does not depend on the size or amount of the material being measured. It is a characteristic of the material itself, not influenced by the quantity.
Does the value of thermal conductivity depend on the dimension of the specimen?
Thermal conductivity is an intensive property. It is inherent in the material but not dependent on the amount of material. This should not be confused with the rate of heat conduction which can depend on the dimensions of a material. There is one case where the thermal conductivity might depend on the dimension of the material - when the conductivity is not uniform with direction, i.e. where conductivity laterally is different from conductivity longitudinally. When the orientation of the material changes the conductivity, the dimensions can have an effect on the apparent bulk thermal conductivity.
Do all substances warm up at the same rate?
no because energy always flows from the hotter object to the cooler object. it will continue to flow until the two objects reach the same temperature. when both molecules are at the same temperature, the molecules will have the same kinetic energy.
Does temperature depends on the amount of substances?
actually no it doesnt
How can mixtures of the same substances be different?
Depending up on the variable amount of different substances in the mixtures these can be different.
What is the relationship between salinity and conductivity in water?
The relationship between salinity and conductivity in water is that as the amount of dissolved salts in water increases, the conductivity also increases. This is because salts in water break down into charged particles called ions, which can conduct electricity. Therefore, higher salinity levels result in higher conductivity levels in water.
Why do think different substances heat up and cool down at different rates?
Different substances heat up and cool down at different rates due to variations in their specific heat capacities, thermal conductivity, and molecular structures. Specific heat capacity is the amount of energy required to raise the temperature of a substance, which varies widely among materials. Additionally, thermal conductivity affects how quickly heat is transferred through a substance. These properties are influenced by the arrangement and bonding of atoms or molecules within the material, leading to distinct thermal behaviors.
Classify this property as intensive or extensive electric conductivity Click on the correct answer?
Electric conductivity is classified as an intensive property. Intensive properties do not depend on the amount of substance present, and electric conductivity remains constant regardless of the sample size. Thus, it is a characteristic property of the material itself.
