The density of water is maximum at 4 °C because, at this temperature, two opposing effects are in balance.
Why does water has maximum density at 4 C?
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.
Why is the density of water maximum at 277 K?
Above 277K: Expansion factor (due to increase in thermal energy) becomes greater than the contraction effect (caused by breaking of hydrogen bonds), naturally, volume increases and the density decreases. Thus, the density of water is maximum at 277 K.
Which phase of water has the highest density?
Answer: b (liquid)
See full answer below.
Which has maximum density?
An especially notable irregular maximum density is that of water, which reaches a density peak at 3.98 °C (39.16 °F). The density varies with temperature, but not linearly: as the temperature increases, the density rises to a peak at 3.98 °C (39.16 °F) and then decreases.
Which has highest density?
As it turns out, either of two elements can be considered the element with the highest density: osmium or iridium. Both osmium and iridium are very dense metals, each weighing approximately twice as much as lead.
What happens to water between 0 and 4 degrees Celsius?
Learn more physics!
A: 4 degrees C turns out to be the temperature at which liquid water has the highest density. If you heat it or cool it, it will expand. The expansion of water when you cool it to lower temperatures is unusual, since most liquids contract when they’re cooled.
Why does water expand below 4 degrees?
Originally Answered: Why does water expand when cooled at specially 4 degrees Celsius ? It’s due to the specific bonding between the H2O molecules. As water freezes and becomes a solid it is actually less dense than water at 0 degrees. Therefore you have the unusual situation of it decreasing in volume as it melts.
Is density of water is maximum at 273 K?
Density of water is maximum at 277K(4∘C).
At what temperature density of water is maximum in Kelvin?
At 4oC, the density of water is maximum. Its value is 1000 kgm−3.
Why does ice has less density than water?
When ice melts, some of hydrogen bonds break and some empty spaces are occupied by water molecules. Liquid water molecules are more closely packed than molecules in ice. Hence, ice has lower density than water.
What is the minimum density of water?
If we look at the records water is at maximum density or densest (1g/cm3) at a temperature of about 3.98°C. On the other hand, it is said to be the least dense at 0°C (0.9998g/cm3). Normally, density is measured as mass (g) per unit of volume (cm³). Was this answer helpful?
