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.
What is negative about paper?
The paper is probably negatively charged, polar too, hence absorbs water.
What does Octisalate mean?
Octisalate a substituted salicylate that absorbs ultraviolet light in the UVB range, it is used as a sunscreen.
What does the term endosperm haustoria mean?
Endosperm means the tissue that is found when like a flowering plant is undergoing fertilization. Haustoria is something found that absorbs the nutrients or water of another plant. Endosperm Haustoria is basically a rootlike structure that absorbs the nutrients of a plant when it is in its fertilization stage(the plant is flowering).
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?
increases in temperature. This increase in temperature causes the molecules to vibrate and move more, leading to an expansion of the substance.
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?
The temperature of the substance receiving the heat increases as it absorbs the thermal energy transferred from the other substance. Heat flow typically results in a temperature change until thermal equilibrium is reached, where both substances are at the same temperature.
50g of a substance's temperature increase from 20C to 40C when it absorbs 250 calories of heat What are its heat capacity and its specific heat in joules?
345 J ok good
When an object absorbs heat energy what increases?
When an object absorbs heat energy, its internal energy increases. This increase in internal energy can lead to a rise in temperature, causing the molecules in the object to move faster.
Does freezing absorbs heat energy?
Yes, freezing involves removing heat energy from a substance, causing it to lower in temperature and eventually solidify. This process absorbs heat energy from the substance itself and its surroundings.
