What is the freezing point (in degrees celsius) of water?

Answer

0° C or 273.15 K or 32°F

Explanation

The ordinary freezing point of water is 0 degrees Celsius. This is also the melting point of water.However,when there is presence of impurities in the water, the freezing point depression occurs.In some conditions,water can remain in liquid state at -40 to -42 ° F.

The freezing point of water is 0°C.

Explanation:

The temperature at which the water changes its state from a liquid to a solid is called the freezing point of water.

The freezing point of pure water is 0°C. However, the state of the liquid is dependent on three different factors which include: temperature, pressure and its chemical composition.

So for different pressures, the freezing point of water varies with it. However,  the presence of any impurities in the water lower its freezing point.

the correct option is option d

the level of progesterone is low at the pre-ovulatory phase of the cycle but it gradually increases and the levels are high at the luteal phase. if pregnancy occurs, the level of progesterone will be high throughout the pregnancy.

if egg is fertilized and the mother gets pregnant, progesterone starts preparing the uterus for the implantation. it starts building up the lining of uterus and make it hostile of the period of pregnancy.
