What is the density of water at different temperatures?
Water’s density varies with temperature
| Temperature (°F/°C) | Density (grams/cm3 | Weight (pounds/ft3 |
|---|---|---|
| 39.2°F/4.0°C | 1.00000 | 62.424 |
| 40°F/4.4°C | 0.99999 | 62.423 |
| 50°F/10°C | 0.99975 | 62.408 |
| 60°F/15.6°C | 0.99907 | 62.366 |
Why is the density of water different at different temperatures?
Density changes with temperature because volume changes with temperature. Density is mass divided by volume. As you heat something up, the volume usually increases because the faster moving molecules are further apart. Since volume is in the denominator, increasing the volume decreases the density.
Does density of seawater change with temperature?
The density of seawater (salinity greater than 24.7) increases as temperature decreases at all temperatures above the freezing point.
At which temp water has highest density?
As water cools it becomes more dense. At 39°F (or 3.98°C to be exact) water is the most dense. This is because the molecules are closest together at this temperature. The closer the molecules, the heavier.
What is the density of water at 60 degrees Fahrenheit?
62.36
| Temperature | Density (0-212°F at 1 atm, >212 °F at saturation pressure) | Specific weight |
|---|---|---|
| 40 | 62.42 | 62.42 |
| 50 | 62.41 | 62.41 |
| 60 | 62.36 | 62.36 |
| 70 | 62.30 | 62.30 |
What is the density of water at 25 degrees?
0.9970 g/mL
We see the same trend in going from liquid water at 25 deg C (0.9970 g/mL) to liquid water at 4 deg C (0.99997 g/mL). Density increase as the temperature decreases.
How much does density change with temperature?
Density is directly proportional to pressure and indirectly proportional to temperature. As pressure increases, with temperature constant, density increases. Conversely when temperature increases, with pressure constant, density decreases.
How does density vary with temperature?
Density and Temperature Relationship When more temperature increases, density reduces. When the temperature decrease, density increases.
Is cold water more dense than warm water?
Cold water has a higher density than warm water. Water gets colder with depth because cold, salty ocean water sinks to the bottom of the ocean basins below the less dense warmer water near the surface.
Is cold water heavier than warm water?
If equal volumes of cold water (down to 4deg. C, 39.2deg. F) and hot water are compared, cold water weighs more than hot water. Students should notice that cold water will sink when placed on top of hot water, and hot water will float on the surface of cold water.
Why is water densest at 4 degrees?
At 4 °C, the clusters start forming. The molecules are still slowing down and coming closer together, but the formation of clusters makes the molecules be further apart. Cluster formation is the bigger effect, so the density starts to decrease. Thus, the density of water is a maximum at 4 °C.
What is the density of water at 25 degrees C?
