In what temperature range does density of water increases with temperature?
Density of water in solid state i.e. ice increases from 0oC to 4oC, where it has maximum density.Ice has a cage-liked structure with lots of vacant spaces in between because of extensive hydrogen bonding between the water molecules. When the temperature increases, this structure collapses as the hydrogen bonding starts to break and as such the water molecules occupy the void spaces thereby increasing the density.Beyond 4oC, the ice melts completely.
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.
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).
Why does density of water below 0 degree Celsius first decreases then increases?
First decreases then increases ... as what changes, exactly? The point of maximum density for liquid water occurs at 3.98 degrees Celsius. This is mainly due to some semi-complicated effects from hydrogen bonding, which is stronger in water than in nearly any other substance.
What relationship of temperature and density of air and water?
As temperature increases, the density of air decreases because the air molecules move further apart. In contrast, as water temperature increases, its density decreases until it reaches its maximum density at around 4 degrees Celsius, after which it decreases. This unique behavior of water is due to its hydrogen bonding and is the reason why ice floats on water.
How does relative humidity vary with changes in temperature?
Relative humidity is the amount of water vapor in the air compared to the maximum amount the air can hold at a given temperature. As temperature increases, the air can hold more water vapor, so relative humidity decreases. Conversely, as temperature decreases, the air can hold less water vapor, so relative humidity increases.
What does the seawaters density do as its temperature decreases?
As seawater temperature decreases, its density increases until it reaches its maximum density at around 4 degrees Celsius. Further cooling below this temperature causes the density to decrease due to the formation of ice, which is less dense than liquid water.
What does the density of water do As the temperature of seawater decreases?
As the temperature of seawater decreases, its density increases until it reaches its maximum density at around 4 degrees Celsius. Below 4 degrees Celsius, seawater begins to decrease in density due to the formation of ice crystals, which causes it to float. This unique property of water helps regulate oceanic and atmospheric circulation patterns.
What is Wien's displacement constant?
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.

When water at zero degree Celsius is heated its volume?
When water at zero degrees Celsius is heated, its volume initially decreases until it reaches its maximum density at 4 degrees Celsius. Beyond this temperature, as the water continues to heat up, it expands and its volume increases.
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
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
State the relationship between water temperature and the maximum mass of ammonium chloride that can be dissolved in 100 grams of water?
Oh, dude, you're asking about solubility, huh? Well, the relationship between water temperature and the maximum mass of ammonium chloride that can dissolve in water is that as the temperature increases, more ammonium chloride can dissolve. It's like when you heat up soup on the stove and it dissolves faster, but with chemicals instead. So, basically, crank up the heat if you want more ammonium chloride to disappear into your water.

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.
