Freezing the sample causes the molecules to slow down and come closer together, often leading to a decrease in volume and possibly forming a solid. Boiling the sample provides energy to the molecules, causing them to separate from each other and enter a gaseous state, thereby increasing the volume.
What else can I help you with?
What effect does the amount of the sample of a substance affect its density?
it has no effect. density of a substance is the same no matter the size or shape of the sample.
How would the measured value of specific heat be affected if some boiling water were carried over with the sample?
If boiling water were carried over with the sample, it would increase the measured value of the specific heat. The excess heat energy from the boiling water would contribute to raising the overall temperature of the sample, leading to a higher specific heat value being calculated.
Would there be a difference in the boiling point temperature of water between a cup of water and a bathtub of water?
No. Boiling point is an intensive physical property, which means it does not matter how large the sample is.
What is a charateristic poperty?
A characteristic property is a chemical or physical property that helps identify and classify substances. The characteristic properties of a substance are always the same whether the sample you are observing is large or small. Examples of characteristic properties include freezing/melting point, boiling/condensing point, density, magnetism, and solubility.
When a liquid sample is taken from sea level to a higher elevation what happens to the external pressure on the liquid and the boiling point of the liquid?
atmospheric pressure is lower and the boiling point is less
How are boiling and freezing points of a sample of water affected when salt is dissolved in the water?
the freezing and boiling points rise significantly- this is why when you boil water in a saucepan, like for pasta, it is advised that you put salt in the water so that the water boils at a higher temperature, thus allowing you to heat the water to a higher temperature. hope this helps
Why wont a sample statistics change from sample to sample?
The sample mean may differ from the population mean, especially for small samples.
Why do most sample means differ somewhat from the population mean?
The sample is not a perfect representation of the population.
What can you conclude about two liquid samples that have boiling points?
The liquid sample with the higher boiling point likely has stronger intermolecular forces, such as hydrogen bonding or dipole-dipole interactions, compared to the liquid sample with the lower boiling point. Boiling point is a reflection of the strength of intermolecular forces in a substance.
How do a control sample and an experimental sample differ from each other?
A control sample is the experiment under regular conditions. An experimental sample is the experiment in which different variables are changed.
What effect does the amount of the sample of a substance affect its density?
it has no effect. density of a substance is the same no matter the size or shape of the sample.
How would the measured value of specific heat be affected if some boiling water were carried over with the sample?
If boiling water were carried over with the sample, it would increase the measured value of the specific heat. The excess heat energy from the boiling water would contribute to raising the overall temperature of the sample, leading to a higher specific heat value being calculated.
What does snap freezing do?
Snap freezing is a rapid method of freezing biological samples to preserve cellular structures and biomolecules. It involves quickly freezing the sample at very low temperatures to prevent ice crystal formation, which can damage the cellular integrity. Snap freezing is commonly used in research and clinical settings to capture a snapshot of the sample's state at a specific moment in time.
Can The mean and standard deviation change?
They will differ from one sample to another.
What is the overall effect of adding heat to any sample of particles regardless of its phase or state?
Adding heat to a sample of particles increases their average kinetic energy, causing the particles to move faster and collide more frequently. This can lead to changes in the phase or state of the sample, such as melting, boiling, or sublimation, depending on the specific material.
How do you decide whether a colourless liquid is pure water by boiling?
By boiling the substance, you can compare the actual boiling point of water in given conditions to that of the sample. However, analogues can be made which will have an identical boiling point, yet contain little or no water at all. Hence, boiling alone cannot ascertain what something is. This holds for all physical tests - you must use chemical tests as well to determine exactly what composes a sample.
When a sample of water is heated past 100 degrees Celsius its past its?
When a sample of water is heated past 100 degrees Celsius, it is past its boiling point. At this temperature, water changes from a liquid to a gas.
