Troposphere increase or decrease in air temp?
The temperature in the troposphere generally decreases with increasing elevation, at a rate of about 6.5 degrees Celsius per 1,000 meters. This decrease in temperature is due to the decreasing density of air molecules at higher altitudes, which leads to less efficient heat transfer.
What happens to temperature in the troposphere?
In the troposphere, temperature generally decreases with increasing altitude at a rate of around 6.5°C per kilometer due to the adiabatic cooling effect as air pressure decreases with height. This relationship is known as the environmental lapse rate and defines the temperature profile of the troposphere.
Which layer extends to an average altitude of about 12 km?
The troposphere is the layer of the atmosphere that extends to an average altitude of about 12 km. This is where most weather phenomena occur and where temperature generally decreases with increasing altitude.
How do pressure and temperature vary in the atmosphere?
In the atmosphere, pressure generally decreases with higher altitude due to the decrease in air density. Temperature changes can vary depending on altitude and location, but in general, the temperature decreases with increasing altitude in the troposphere, remains relatively constant in the stratosphere, and then increases in the mesosphere and thermosphere.
Is temperature inversely proportional to concentration of oxygen?
No, temperature and concentration of oxygen are not inversely proportional. Changes in temperature can affect the solubility of oxygen in water, but the relationship is not strictly inverse. The solubility of oxygen generally decreases with increasing temperature.
What weather variable generally decreases when wind speed is increasing clouds are thickening and visibility drops?
When wind speed increases, clouds thicken, and visibility drops, the weather variable that generally decreases is temperature. This is often associated with the arrival of a cold front, where cooler air replaces warmer air, leading to a drop in temperature. Additionally, increased cloud cover can block sunlight, further contributing to a decrease in temperature.
How does increasing the temperature of a gas solvent affect the solubility of a gas?
Increasing the temperature of a solvent decreases the solubility of a gas Generally, increasing solvent temperature decreases the solubility of gases.
How does increasing temperature affect the solubility of a gas solute?
Increasing temperature decreases the solubility of a gas solute in a liquid solvent. This is because higher temperatures increase the kinetic energy of molecules, leading to weaker gas-liquid interactions and reduced solubility.
How does electronegative change going down and across the periodic table?
Electronegativity generally decreases as you go down a group on the periodic table due to the increasing distance between the nucleus and valence electrons, reducing the attractive force. Across a period, electronegativity generally increases due to the increasing nuclear charge, pulling valence electrons closer and increasing their attraction.
What is the gravitational acceleration inside a planet?
The gravitational acceleration inside a planet is determined by its mass and radius. It generally decreases as you move towards the center of the planet due to the increasing mass above you.
Troposphere increase or decrease in air temp?
The temperature in the troposphere generally decreases with increasing elevation, at a rate of about 6.5 degrees Celsius per 1,000 meters. This decrease in temperature is due to the decreasing density of air molecules at higher altitudes, which leads to less efficient heat transfer.
What is it called when you add gelatine to something?
The process is called jellyfying or more generally thickening.
In general howe dose atomic radius change across a period from letf to right?
Atomic radius generally decreases across a period from left to right. This is due to the increasing nuclear charge pulling the electrons closer to the nucleus, making the atomic size smaller.
Which conducts electricity better a hot piece of steel or a cold piece of steel?
The electrical conductivity of a metal generally decreases with increasing temperature. Inversely, the electrical conductivity of a semi-conductor increases with increasing temperature.Source: UK GCSE (high school) science education.
What trend does the first ionization energy follow in the periodic table?
The first ionization energy generally increases across a period from left to right due to increasing nuclear charge and decreasing atomic size. It decreases down a group due to increasing atomic size and shielding effect from inner electrons, making it easier to remove an outer electron.
What is the periodic trend for electrongativity?
Electronegativity generally increases from left to right across a period and decreases from top to bottom within a group on the periodic table. This trend is due to the increasing nuclear charge across a period and the increasing distance between the nucleus and valence electrons down a group.
How do you increase viscosity?
Viscosity is the resistance of a liquid to flow. When temperature decreases Viscosity generally increases. Viscosity generally decreases when the temperature increases.
