Why does water temperature increase when mixed with Isopropyl?
When isopropyl alcohol is mixed with water, it releases energy due to the solvation process, leading to an overall increase in temperature. This is because energy is released when the intermolecular forces between water molecules and isopropyl alcohol molecules are formed.
Why doesn't air pressure increase?
Air pressure doesn't increase indefinitely because it is governed by the balance of atmospheric forces and the behavior of gas molecules. As altitude increases, the density of air decreases, leading to lower air pressure. Additionally, atmospheric pressure is influenced by temperature, humidity, and weather patterns, which can cause fluctuations rather than a steady increase. Ultimately, the Earth's atmosphere has a finite amount of gases, and as these gases spread out, they create a limit on how much pressure can build up.
Why does physisorption decrease with the increase of temperature?
Physisorption is weaker than chemisorption and is typically dependent on van der Waals forces. As temperature increases, the thermal energy disrupts these weak interactions between the adsorbate and the surface, leading to a decrease in physisorption.
An increase in temperature causes a decrease in the amount of gas able to dissolve in a liquid solvent Why does this occur?
As temperature increases the mean kinetic energy of all particles present increase, allowing for the gases dissolved to evaporate more readily, as they are in a greater state of vibratory motion - that is they are present in a more gaseous form. Phase is determined by the extent of motion of particles, which is determined by the intermolecular forces acting between molecules. An increase in temperature will also increase the motion of dissolved particles by weakening the forces acting between the solute and solvent. This allows the dissolved gases to evaporate out of solution. Hence an increase in temperature corresponds to a decrease in the solubility of gases in liquids. Hope it helps. By Vibs
Is surface tension increases or decreases with increase in temperature?
Surface tension decreases with an increase in temperature. This is because as temperature increases, the kinetic energy of the water molecules also increases, which weakens the intermolecular forces responsible for surface tension.
Can an atmosphere in which the temperature and the density are increasing with elevation be in gravitational equilibrium?
No, an atmosphere in which temperature and density increase with elevation cannot be in gravitational equilibrium. In a stable atmosphere, temperature generally decreases with altitude due to the balance between gravitational forces and thermal buoyancy. An increase in both temperature and density with elevation would lead to an unstable situation, causing the denser, cooler air below to rise, disrupting equilibrium.
Do intermolecular forces increase as temperature rises?
Yes, intermolecular forces generally increase as temperature rises. This is because higher temperatures cause molecules to move faster and collide more frequently, leading to stronger interactions between them.
What is the effect of increase of temperature on surface tension?
An increase in temperature typically decreases surface tension in liquids. This is because higher temperature leads to increased molecular motion, which weakens the intermolecular forces responsible for surface tension.
In which layer of the atmosphere does most of Earth's weather occur?
Ultimately, major driving forces of weather on earth are uneven heating of the surface and moisture. The vast majority of the moisture in Earth's atmosphere is in the troposphere. The amounts in other layers are generally inconsequential. The troposphere is also the only layer that interacts directly with Earth's surface and is impacted by surface temperature, moisture content and the terrain. The other layers do not encounter such varied environments and so are realtively uniform compared to the troposphere.
What forces cause wind to blow at altitude?
friction
How do tsunamis relate to the troposphere?
The don't. The troposphere is the layer of earth's atmosphere where most weather occurs. Tsunamis are triggered by forces within the earth, completely unrealted to the weather.

does solid to gas increase or decrease tempearture?
When a solid changes to a gas (sublimation), it absorbs energy from its surroundings, leading to a decrease in temperature. The energy is used to break the intermolecular forces holding the solid together, rather than raising the temperature.
What happens to the solubility of gases with the increase in temperature?
The solubility of gases generally decreases with an increase in temperature. This is because elevated temperatures disrupt the intermolecular forces holding the gas molecules in the liquid solvent, making it easier for the gas to escape into the atmosphere.
If you increase the pressure the boiling point will increase or remain same?
If you increase the pressure, the boiling point of a substance will increase. This is because higher pressure leads to stronger intermolecular forces, requiring more energy to overcome them for the substance to boil.
Why does water temperature increase when mixed with Isopropyl?
When isopropyl alcohol is mixed with water, it releases energy due to the solvation process, leading to an overall increase in temperature. This is because energy is released when the intermolecular forces between water molecules and isopropyl alcohol molecules are formed.
The tendency of the molecules of a liquid at a given tepmpature to evaporate as a result of radom molecular motion?
This is known as vapor pressure. It is influenced by factors like temperature, intermolecular forces, and surface area. Higher temperature and weaker intermolecular forces increase the vapor pressure of a liquid.
