Is the process of adding dish soap to water in a sink a physical or chemical change?
The process of adding dish soap to water in a sink is a physical change.
Does adding salt to water change its pH level to become more alkaline?
No, adding salt to water does not change its pH level to become more alkaline. Salt does not directly affect the pH level of water.
Is adding dish soap to water in a sink considered a chemical change?
No, adding dish soap to water in a sink is not considered a chemical change. It is a physical change because the substances involved do not undergo a chemical reaction to form new substances.
Is adding water to pot noodles a physical change?
This depends. Are the pot noodles dry at room temperature? Then not yet .Are the pot noodles in boiling water? Is the water you are adding from the cold water tap? Then, Yes, as boiling will stop until the new water is at boiling temperature.
Is adding of calcium to water a chemical change?
Adding calcium to water is a physical change because it does not alter the chemical composition of either the calcium or water molecules. The calcium simply dissolves in the water to form calcium ions and does not undergo a chemical reaction.
How does change in buoyancy affect the function of a submarine?
A change in buoyancy affects a submarine's ability to rise and sink in the water. By adjusting the amount of water in its ballast tanks, the submarine can control its buoyancy and depth in the water. This is essential for navigating through different depths and maintaining stability.
Are PFD's more buoyant in deep water than in shallow water?
No, the buoyancy of a PFD does not change based on the depth of the water. The buoyancy of a PFD is based on its design and materials, not the depth of the water. It will provide the same level of buoyancy regardless of the water depth.
What affect provided by water aerobics helps make the exercise beneficial?
Buoyancy
Why does plain water boil faster than vinegar water?
Adding vinegar to water the effect of boiling point elevation occur.
Can you buoyancy a egg?
Yes, you can make an egg float in water by adding salt to increase the water's density. This creates a higher buoyant force that counters the egg's weight.
What is the function of the ballast tanks on a submarine?
To change the buoyancy of the boat and allow it to rise and sink in the water.
Is the process of adding dish soap to water in a sink a physical or chemical change?
The process of adding dish soap to water in a sink is a physical change.
Will a swimmer gain or lose buoyant force as she swims deeper in the water?
If she is completely immersed, there would only be a change if the water changes density (unlikely) or she changes her volume (also unlikely) as the buoyancy force is the product of her volume under the water, the density of the fluid and gravitational acceleration. If none of those change, then the buoyancy force will not change.
Is adding hot water to pot noodles a physical change?
Adding hot water to pot noodle is a physical change because the chemical nature of water remain unchanged.
How does buoyancy affects a boat?
Buoyancy affects a boat by keeping it "on" the water, not "under" the water.
Are Personal Floation Divcess more buoyant in deep water?
No the depth of the water does not change buoyancy. Floating in salt water is easier than in freshwater.
Is adding starch in water chemical change?
Yes
