What is the final velocity of an object that decreases in kinetic energy and increases in potential energy?
Its final velocity will be zero when it reaches maximum potential energy.
As water is cooled 4c to 0c its density?
the density of water is mostly high when its at 4 degrees celsius so the answer would be that the density of the water decreases from 4 degrees celsius to 0 degrees celcius
What happens to the light emitted by a heated object as its temperature increases?
Initially invisible infra red radiations. Then as temperature increases it becomes red. As still temperature increases it turns into yellow. When further increase happens, it starts giving out almost all colors including blue, violet and so it seems white hot. As an object is heated, it's maximum electromagnetic frequency increases. So you can measure the heat of an object by its emitted spectrum.
Which is the greater energy the potential energy or kinetic energy?
Typically higher. Consider a gas. The air you breath is made up of billions of particles flying around all over the place. When the air is warm, these particles move faster than if the air was cold. In that sense, temperature is higher if kinetic energy is great.
Are the number of sunspots on the sun's surface always the same?
No, sunspot activity increases and decreases. Scientists have observed that the level of sunspot activity follows a cycle of about 11 years (11 years from maximum to maximum and 11 years from minimum to minimum).
What is constant displacement?
In Wien's experiment it was found that when the temperature of the source increases, then the wavelength for which the radiant energy becomes maximum decreases. This displacement towards the lower wavelength side as temperature increases is termed as displacement law. So if T, the temperature of the source in kelvin and lambda m is the wavelength for which the energy is maximum. Then lambdam *T = constant. This constant is known as Wien's constant, whose value is 5.67 x 10-8 mK.

How are temperature and humidity not related?
By marriage. Humidity and temperature are related. The maximum absolute humidity increases with temperature and pressure (up to the boiling point).
What is the final velocity of an object that decreases in kinetic energy and increases in potential energy?
Its final velocity will be zero when it reaches maximum potential energy.
How does temperature effect diffusion rates?
Temperature and diffusion rates are usually linearly proportional. As temperature increases diffusion rate also increases and vice versa. In most cases, diffusion rate will reach 0 after saturation or the maximum possible temperature.
State the relationship between water temperature and the maximum mass of ammonium chloride that can be dissolved in 100 grams of water?
As the temperature of the water increases, the amount of solute (in this case NH4Cl) that can be dissolved increases.
When is the speed of a fluid maximum in a venturi meter?
from the continuity equation A1v1 = A2v2 according to the continuity equation as the area decreases the velocity of the flow of the liquid increases and hence maximum velocity can be obtained at its throat
As water is cooled 4c to 0c its density?
the density of water is mostly high when its at 4 degrees celsius so the answer would be that the density of the water decreases from 4 degrees celsius to 0 degrees celcius
What are the effects temperature and pH level have in the efficacy of digestive enzymes?
As you increase the temperature at first the activity of an enzymes will also increase, so the reaction will go faster. At a certain temperature, called the optimum temperature, the enzyme will work at its maximum rate. Above the optimum temperature the enzyme activity decreases. This is due to the loss of shape by the enzyme molecules, a process called denaturation. In mammals, most enzyme shave an optimum temperature of about 37 oC. Roughly speaking, the rate of an enzyme reaction doubles for each 10 oC rise in temperature, until the optimum temperature is reached. pH affects enzymes in a similar way. At a low pH many enzymes have a low activity. As the pH increases the enzyme activity increases until the optimum pH at which the enzyme has maximum activity. Above this pH enzyme activity decreases. These effects are also dueto denaturation of the enzyme molecules at extreme pH values. Many enzymes work best at around pH 7.0. An important exception is pepsin, a protein-digesting (protease) enzyme in the stomach. This works at low pH values such as those found in the stomach (around pH 2.0), due to the presence of hydrochloric acid.
What happens when an enzyme catalyzes a reaction?
The rate of a reactions usually increases when catalyzed by an enzyme. For maximum rate of activity, the enzyme needs optimal conditions.

When is water more buoyant - in winter or summer?
The density of water increases as the temperature decreases and approaches a maximum at 4oC. After this point the density decreases until 0oC at which point the water changes to ice.The density and the buoyant force of the water therefore increases until the 4oC point at which time it decreases slightly:Temp ( °C ) : Density (g/cm3)0 : 0.99994 : 1.00020 : 0.998240 : 0.992260 : 0.983280 : 0.9718Using Lake Superior as an example, the surface water temperature varies between 20oC July/August and slightly above 0oC in December/January. The water provides 1% more buoyancy (it's density is 1% higher) in winter.
