Why same amount of heat supplied to same amount of different substances does not produce the same increase in temperature?
There is a formula in physics ΔQ=m*c*ΔT, where m is the mass of the substance you are heating, ΔQ is the heat you supply to the substance, c is the specific heat which has a different value for different substances and ΔT is the change in temperature. If your substances are different and they have the same mass then by supplying the same amount of heat the change in temperature will be different.
You apply the same amount of heat to five grams of substance a and five grams of substance b the temperature of both substances increase by the same amount what can you conclude?
You can conclude that both substances have the same specific heat capacity. This means that they require the same amount of energy to change their temperature by a certain amount.
A difference in this results in different ending temperatures when the same amount of thermal energy is added to two different substances?
The specific heat capacity of a substance determines how much thermal energy is needed to raise its temperature. Therefore, substances with different specific heat capacities will reach different ending temperatures when the same amount of thermal energy is added. Substances with higher specific heat capacities will have smaller temperature increases compared to substances with lower specific heat capacities.
A difference in the results in different ending temperatures when the same amount of thermal energy is added to two different substances is called what?
That difference is called specific heat capacity. Specific heat capacity is a measure of how much heat energy is required to raise the temperature of a substance by a certain amount, so substances with different specific heat capacities will experience different temperature changes when the same amount of thermal energy is added.
What substances require the most energy to heat up a unit mass by 1celsius?
Substances with high specific heat capacities require more energy to heat up a unit mass by 1 degree Celsius. Water has one of the highest specific heat capacities of common substances, meaning it requires a significant amount of energy to raise its temperature. Metals like lead and mercury, on the other hand, have lower specific heat capacities and require less energy to heat up.
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.
Why same amount of heat supplied to same amount of different substances does not produce the same increase in temperature?
There is a formula in physics ΔQ=m*c*ΔT, where m is the mass of the substance you are heating, ΔQ is the heat you supply to the substance, c is the specific heat which has a different value for different substances and ΔT is the change in temperature. If your substances are different and they have the same mass then by supplying the same amount of heat the change in temperature will be different.
What effect would increasing the quantity of paradichlorobenzene have on the melting point temperature?
The melting point of the substance should not change as all substances have specific melting, boiling, condensation, and freezing points. It would, however, require more energy (in this case, heat) to melt the increased quantity of paradichlorobenzene in the same amount of time.
Why sodium has a high melting temperature?
Sodium has a high melting temperature because it has strong metallic bonds between its atoms. These bonds require a significant amount of energy to break, resulting in a high melting point for sodium.
Why do different substances have different melting points?
Substances may contain more elements than the other substance, meaning that it would take more energy (heat) to break the bonds of the substance as opposed to the other substance. Because these bonds must break in order to change phases, it would take more energy to dismantle the larger substance. Another thing that affects melting points is the types of bonds that connects the atoms to each other. Double bonds take more energy to break than single bonds. Triple bonds take more energy than double bonds so that could also account for the differences in melting points between two substances.
What energy is the minimum amount of energy required for substances undergo change to produce one or more different substances?
activation energy
You apply the same amount of heat to five grams of substance a and five grams of substance b the temperature of both substances increase by the same amount what can you conclude?
You can conclude that both substances have the same specific heat capacity. This means that they require the same amount of energy to change their temperature by a certain amount.
When there are different amount of substances on either side of cell membrane a gradient results?
osmosis
Do Different substances have different solubilities?
Yes, different substances have different solubilities which determine the amount of solute that can dissolve in a solvent at a given temperature. Solubility depends on factors such as the nature of the solute and solvent, temperature, and pressure. There are soluble substances that dissolve well in a solvent, while insoluble substances do not dissolve.
How potassium iodide have a high melting point?
Potassium iodide has a high melting point because it consists of strong ionic bonds between potassium and iodine atoms. These bonds require a significant amount of energy to break, resulting in a high melting point for the compound.
What is biogradable substances?
Biogradable substances are substances which can be graded in to different substances.for instance water is H2o. two amounts of hydrogen and one amount of oxygen combined to make a liquid.
What are the melting and boiling points of different substances?
At 1atm, the melting point of H2O(water) is 0 degrees celcius and the boiling point is 100 degrees celcius. Carbon dioxide's boiling point is at -25 degrees and so its meting point. Since it crystallises and sublimates, it has no liquid form. The boiling- and melting points of elements/compounds depend on the amount of pressure exerted on the element/compound. Generally, the higher the pressure, the higher the boiling and melting points. All except for water, gallium and bismuth. These substances' melting point decreases as pressure increases.
