Question

I want this answer urgently please

Answer 1

ice floats on water because it is lighter than water

the melting point of ice is 0°c

our body temperature is maintained at 37°c

HOPE IT HELPSS

Answer 2

Answer:

Here is your Answer

Explanation:

1. The density of water is the weight of the water per its unit volume, which depends on the temperature of the water. The usual value used in calculations is 1 gram per milliliter (1 g/ml) or 1 gram per cubic centimeter (1 g/cm3). While you can round the density to 1 gram per milliliter, there are more precise values for you to use.
2. Ice floats because it is about 9% less dense than liquid water. In other words, ice takes up about 9% more space than water, so a liter of ice weighs less than liter water. The heavier water displaces the lighter ice, so ice floats to the top.
3. Our internal body temperature is regulated by a part of our brain called the hypothalamus. The hypothalamus checks our current temperature and compares it with the normal temperature of about 37°C. If our temperature is too low, the hypothalamus makes sure that the body generates and maintains heat.
4. For ice, the melting point is 0°C or 273K. The temperature of the reverse change from liquid to solid is called the freezing point or crystallization point. For most substances the melting point and freezing points are equal.
