What are the of offical mesures of deliquesce?

Official measures of deliquescence typically refer to the temperature and humidity conditions under which a substance absorbs moisture from the air to the point of forming a liquid solution. The deliquescent point is often characterized by specific relative humidity levels at a given temperature, which can vary for different substances. Standardized tests may involve measuring these conditions in controlled environments to determine the deliquescent properties of hygroscopic materials.


What does hygroscopic mean?

It means any substance that readily absorbs moisture, like from the atmosphere. i.e wool goes by this term therefore has thermal qualities when laid as a carpet, in winter it absorbs the moist cold air leaving the atmospere in the room warmer and in summer it actually absorbs up to 30% of the humidity thus leaving it cooler.


What is being measured by an outdoor thermometer?

If it's in the shade, then the temperature of the air that wafts past it is. If it's in direct sun, then it's displaying the temperature of the structure of the thermometer itself, as it absorbs direct solar radiation and its temperature rises above that of the air that wafts past it.


Why temp is low at 25000 ft And high at ground?

The temperature is lower at higher altitudes, such as 25,000 feet, compared to at ground level due to a few key reasons: Decrease in Air Pressure: As altitude increases, air pressure decreases. Lower pressure means that the air is less dense and has fewer air molecules to absorb and retain heat. Adiabatic Cooling: As air rises, it expands due to the decreasing atmospheric pressure. This expansion causes the air to cool, a process known as adiabatic cooling. This is why temperatures drop as altitude increases. Radiation and Heat Retention: The Earth's surface absorbs solar radiation and then re-radiates it as heat. At higher altitudes, there's less atmosphere to trap and retain this heat, so the air is cooler compared to at the ground level where heat is more effectively retained. Temperature Inversion: In some cases, temperature inversion can occur where warmer air is trapped above cooler air. However, generally, temperatures decrease with altitude in the troposphere, the layer of the atmosphere closest to Earth where weather occurs. So, the combination of lower air pressure, adiabatic cooling, and the reduced heat retention at higher altitudes results in cooler temperatures as you go higher.


What is negative about paper?

The paper is probably negatively charged, polar too, hence absorbs water.

Does the substance become cooler when it absorbs thermal energy?

No, the substance absorbs thermal energy and its temperature increases, not decreases. Cooling occurs when the substance releases thermal energy.


What happens to the thermal energy of a substance as its temperature increases?

As the temperature of a substance increases, its thermal energy also increases. This leads to greater kinetic energy of the particles within the substance, causing them to move faster and creating more thermal energy.


When matter absorbs heat what is its temperature?

When matter absorbs heat, its temperature generally increases. The extent of the temperature increase will depend on factors such as the amount of heat absorbed, the specific heat capacity of the material, and its mass.


When a substance absorbs heat its molecules move faster and it?

And farther apart, and it changes phase: ice to water, water to gas,


What is the relationship between the wavelength of light and absorbance in a given substance?

The relationship between the wavelength of light and absorbance in a substance is that different substances absorb light at specific wavelengths. This absorption is measured as absorbance, which increases as the substance absorbs more light at its specific wavelength.


What is true for a substance that absorbs energy?

When a substance absorbs energy, its internal energy increases, which can lead to a rise in temperature, a change in phase (e.g., from solid to liquid), or chemical reactions. Absorbing energy typically causes the substance's particles to move more quickly or rearrange themselves in a way that stores the additional energy.


Does the Ozone elevate the temperature of the planet?

Ozone is a greenhouse gas. It absorbs radiation and increases the temperature.


If a surface absorbs insolation its temperature?

If a surface absorbs insolation, its temperature tends to increase as the absorbed energy is converted into heat. The surface absorbs sunlight and converts it into thermal energy, leading to a rise in temperature.


When a substance loses or absorbs energy its temperature can change true or false?

True. When a substance loses energy, its temperature can decrease, while when it absorbs energy, its temperature can increase. This is because energy is transferred as heat, which can lead to changes in temperature.


When heat flows from one substance to another what happens to the temperature of the substance receiving the heat?

If heat leaves a substance, it becomes colder (temperature falls) and when heat enters it becomes warmer (temperature climbs). Note that, because of entropy, heat will only go from warm to cold things.
