Is the solubility of solids in water independent of pressure above solution?
Generally, the solubility of solids in water is not significantly affected by pressure above the solution. However, solubility can be influenced by certain factors such as temperature and the presence of other solutes. Therefore, while pressure may have a minimal impact on solubility, these other factors are typically more influential.
Does eating mango increase internal body temperature?
No, eating mango does not directly increase internal body temperature. However, the digestion process may generate some heat as energy is expended to break down and absorb the nutrients, but this increase in body temperature is minimal and typically temporary.
When water falls from height what will be the effect on its temperature?
When water falls from a height, it gains kinetic energy. This increase in kinetic energy is converted to an increase in temperature due to friction with the air and surrounding surfaces. Overall, the water will experience a slight increase in temperature as it falls.
How much does the population in Africa decrease and increase each year?
The population in Africa increases by approximately 2.5% per year, which accounts for natural growth (births minus deaths) and migration. The rate of decrease is minimal and varies by country, often influenced by factors such as disease outbreaks, conflict, and emigration.
A person shakes a sealed insulated bottle containing hot coffee for a few minutes what is the change in the temperature of the coffee. what is the change in the internal energy of the coffee?
There is a large increase in the temperature of the coffee due to the large amount of kinetic energy inputed into the system through the shaking motion. Thus due to the heat being released there is a large decrease in the internal energy of the system.

Why does solubility of solids and gases change with temperature?
The solubility of solids generally gets higher as the temperature gets higher. (apart from with calcium hydroxide- limewater). The opposite is true for gases- their solubility decreases as the temperature increases.
What factors affecting solubility of solid solute?
1. the nature of solute/solvent2. temperature3. pressure4. stirring5. surface area of the solute6. some added compounds7. amount of the solute8. the geometry of the beaker
What is a minimal internal temperature?
Minimal internal temperature is the least internal temperature you should cook your food. For instance if the recipe says 145 degrees F to 150 degrees F, 145 degrees is the minimal temperature.

What is the temperature at which an object's energy is minimal?
An object's energy is minimal at absolute zero, which is 0 Kelvin or -273.15 degrees Celsius. At this temperature, particles have minimal kinetic energy and motion stops.
How does solubility of ionic compounds and gas in water vary with temperature and pressure changes?
For ionic compounds, solubility generally increases with temperature because higher temperatures provide more energy for the ions to overcome the attractive forces holding them together. However, the solubility of gases in water usually decreases with temperature as gases are more soluble at lower temperatures due to their lower kinetic energy. For gases, solubility typically increases with higher pressures because more gas molecules are being forced into the solvent. For ionic compounds, changes in pressure usually have a minimal effect on solubility since the forces holding the ions together are not significantly impacted by changes in pressure.
Explain why pressure affects the solubility of oxygen in water but not the solubility of Nacl in water?
The reason that it effects the solubulity of oxygen is that it is gaseous while NaCl is solid at room temperature. The oxygen molecules are effected by the increase in pressure in the way that there are more of them per unit volume of air if you increase air pressure. This is clearly not the case for the Na and Cl atoms which are ionically bonded to one another and are therefore solid. If you want to know more about the reason that pressure effects the solubility of oxygen in water, have a wee look at partial pressures.
When does friction need to be reduced?
Friction needs to be reduced when trying to increase the efficiency of machines or decrease wear and tear on components. It is also important to reduce friction in situations where smooth movement or minimal heat generation is required.
How much does the population in Africa decrease and increase each year?
The population in Africa increases by approximately 2.5% per year, which accounts for natural growth (births minus deaths) and migration. The rate of decrease is minimal and varies by country, often influenced by factors such as disease outbreaks, conflict, and emigration.
Does working out in a hoodie increase calorie burn?
Working out in a hoodie may increase calorie burn temporarily by raising body temperature and making the body work harder to cool down. However, this increase is likely minimal and not a significant factor in overall calorie burn during exercise.
