How call you tell if a substance is more or less dense then water?
You can determine if a substance is more or less dense than water by comparing their densities. Water has a density of 1 g/cm3 at 4 degrees Celsius. If a substance has a density greater than 1 g/cm3, it is more dense than water. If it has a density less than 1 g/cm3, it is less dense than water.
Would a rock sink more quickly in 10 degrees Celsius water or minus 5 degrees Celsius water?
Trick question: At minus 5 degrees Celsius, water is a solid. A rock would sit on top of it.
Water freezes at 0 Celsius the weather forecast predicts a low temperature overnight of 5 Celsius How many more degrees will the temperature have to fall before the pond freezes?
The temperature will have to fall 5 more degrees to reach freezing point (0 Celsius).
What describes the boiling point?
The boiling point is the temperature at which a substance changes from a liquid to a gas. The boiling point depends on which element you are using. For instance, Water boils at about 100 degrees Celsius; however, oxygen boils at -183 degrees Celsius. As you can see, there is a huge difference which means there are more elements that are way beyond a thousand degrees Celsius.
If hot water is allowed as a sanitizer it must be what degrees?
For water to be used it must be boiled to 100 degrees Celsius and boiled for more than a minute.
What is less dense than water at 4 degrees Celsius?
At 4 degrees Celsius, ice is less dense than water. This is due to the unique crystal structure of ice that causes it to occupy more space, making it less dense than liquid water.
As water is cooled what happens to the density?
As water is cooled, its density increases until it reaches its maximum density at 4 degrees Celsius. Below 4 degrees Celsius, water begins to expand as it freezes, which is why ice is less dense than liquid water.

Is ice more or less dense than water at a temperature at 4 degrees cels ius?
Ice is less dense than water at a temperature of 4 degrees Celsius. This is because the hydrogen bonds in water cause the molecules to be more spread out and less tightly packed compared to when it is in a solid state as ice.
What is most dense ice water or room temperature water?
when liquid water cools the molecules come closer together, water is most dense at 4 degrees Celsius and anything less there is vibrational movement and the hydrogen bonding are more rigid. at this point water expands as it freezes, meaning ice is more dense than water causing it to float.
Is Liquid water less dense or more dense?
Liquid water is more dense than ICE , and More dense than water vapour(steam). Liquid water is at its most dense at 2 oC. Water on freezing to ice expands by about 10% of its volume. This is because of the lattice arrangement of water molecules in ice., which does not occur in liquid water., Hence ice floats on water. (icebergs).
How many more degrees does 87 degrees does it need to boil?
Water boils at 100 degrees Celsius, so 87 degrees is 13 degrees away from boiling.
Would a rock sink more quickly in 10 degrees Celsius water or minus 5 degrees Celsius water?
Trick question: At minus 5 degrees Celsius, water is a solid. A rock would sit on top of it.
As water is cooled from 4 degrees Celsius to 0 degrees Celsius it's density is what?
As water cools from 4 degrees Celsius to 0 degrees Celsius, its density decreases. This decrease in density is due to the formation of hydrogen bonds between water molecules, causing them to arrange in a more organized structure that takes up more space, decreasing the overall density of the water.
What is th difference between celsius and fahrenheit?
Celsius and Fahrenheit are two units of temperature measurement. The main difference is their zero points; water freezes at 0 degrees Celsius and boils at 100 degrees Celsius, while water freezes at 32 degrees Fahrenheit and boils at 212 degrees Fahrenheit. The Celsius scale is more commonly used in scientific settings, while the Fahrenheit scale is more common in the United States.
How does the vapor pressure of water at 10 degrees celsius compare with its vapor pressure at 50 degrees celsius?
The vapor pressure of water at 10 degrees Celsius is lower than at 50 degrees Celsius. As temperature increases, so does the vapor pressure of water because more water molecules have enough energy to escape into the gas phase.
Is warm or cold water denser?
its according to what other temperature of water you are comparing it to. water is densest at 4 degrees C so water that is colder then 4 degrees C is technically less dense then water at 4C. in that case the warmer water is denser. but if you mean warm water to be >4C and cold water to be colder then warm water, but not below 4C, then cold water is more dense then warm water. but the question you are probably trying to get answered would have an answer of cold is denser
