Despite what your teacher told you. There are indeed stupid questions and this is one of them. The only way you can answer this question is to ask another one. How salty is the saltwater?
The density of water increases as it cools from 4 degrees Celsius to 0 degrees Celsius. At 4 degrees Celsius, the density of water is 999.972 kg/m³, and at 0 degrees Celsius the density is 999.8395 kg/m³.
Temperature does not have density.
No, water's density decreases as it cools. Water reaches its maximum density at around 4 degrees Celsius, and as it cools further, the water molecules form a crystalline structure, causing the density to decrease.
Water reaches maximum density at 4 degrees Celsius
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.
4 degrees Celsius, at which point it reaches its highest density. Below 4 degrees Celsius, water expands as it freezes into ice.
Pure water reaches its maximum density at a temperature of approximately 4 degrees Celsius. This is why water typically contracts as it cools below this temperature, but expands as it freezes into ice.
Water is most dense at 4oC. At this temperature it has a density of 1000 kg/m3
Pure water achieves maximum density at 3.98 °C.
The density of pure water at 97 degrees Celsius is approximately 0.971 grams per cubic centimeter. At this temperature, water is less dense compared to at 4 degrees Celsius (which is the temperature at which water has its highest density).
As water at 4 degrees Celsius is heated slightly, it will start to expand and the temperature will increase. This is because water is at its maximum density at 4 degrees Celsius, and heating it will cause the molecules to move faster and spread out, leading to a volume increase and a temperature rise.
The density of water at 4 degrees Celsius is 1.00 grams per cubic centimeter.
