What happens to the solubility of gases when temperature is increased?
Solubility of gases in liquids decreases with increase in temperature. When gases are dissolved in liquids, heat is evolved. Following Le Chatelier's principle, as the temperature increases, the solubility decreases. This is the reason that aquatic species are more comfortable in cold water as compared in warm water.
Why does difussion occur at slower rate when the temperature is low?
Diffusion occurs at a slower rate at lower temperatures because the kinetic energy of the molecules decreases. As the temperature drops, molecules move more slowly and collide less frequently, which reduces their ability to spread and intermingle. Additionally, the lower energy levels result in fewer successful interactions between particles, further hindering the diffusion process.
What causes melting and boiling in terms of the kinetic molecular theory?
The kinetic theory states that when a solid is heated the bonds between the particles are loosened thus making it a liquid.
How does temperature affect the viscosity of ketchup?
Temperature can affect the viscosity of ketchup by changing the flow behavior of its ingredients. At higher temperatures, ketchup becomes less viscous and flows more easily due to reduced interactions between its molecules. Conversely, lower temperatures increase ketchup viscosity as the molecules move slower and have increased interactions, making it thicker and harder to pour.
What changes of temperature on rate of reaction?
The rate of reaction increases with increasing temperature. When the temperature is increased, the kinetic energy of the reacting particles hence the frequency of effective collisions are also increased. Hence the rate of reaction is faster.
How does decreasing the temperature affect the volume of the gas?
As indicated by Charles's Law, at constant pressure, the volume decreases when the temperature decreases. This is due to slowed collisions between molecules.
Why physisorption decreases with increase in temperature?
Physisorption is exothermic in nature. Therefore, in accordance with Le-Chateliere's principle, it decreases with an increase in temperature. This means that physisorption occurs more readily at a lower temperature.
What happens to the temperature in the mesosphere?
The temperature in the mesosphere decreases with altitude, reaching its lowest point at the mesopause, the boundary between the mesosphere and thermosphere. This cooling effect is due to the diminishing density of gas molecules in this region.
Why does the temperature of a cylinder of butane fall when the temperature drops?
When the temperature drops, the average kinetic energy of the molecules in the butane decreases, causing them to slow down. As a result, the overall temperature of the butane decreases. Additionally, the intermolecular forces between the butane molecules become stronger at lower temperatures, leading to a decrease in the overall thermal energy of the system.
How do the molecules in a solid behave and what factors influence their movement and interactions within the solid structure?
In a solid, molecules are tightly packed together and vibrate in place. Factors that influence their movement and interactions within the solid structure include temperature, pressure, and the strength of the bonds between the molecules.
At what particle level do interactions between atoms and molecules occur?
Interactions between atoms and molecules occur at the particle level, specifically at the level of electrons and protons within the atoms and molecules.

What is the relation between fuel oil density and temperature?
The density of fuel oil decreases as temperature increases. This is because as temperature rises, the molecules in the fuel oil spread further apart, resulting in a decrease in density. Conversely, as temperature decreases, the molecules come closer together, leading to an increase in density.
What are 3 types of interactions?
Three types of interactions are physical interactions (such as touch or collision), social interactions (such as communication or cooperation between individuals), and chemical interactions (such as reactions between molecules).
What is the relationship between temperature and viscosity?
There is an inverse relationship between temperature and viscosity. That is, as the temperature increases, the viscosity decreases (the fluidity increases. However, the exact nature of the relationship is far from straightforward.
What causes melting and boiling in terms of the kinetic molecular theory?
The kinetic theory states that when a solid is heated the bonds between the particles are loosened thus making it a liquid.
