At 2 deg. C water is a mainly liquid. Some of it might 'disappear' as dry air may be humidified by the water. Ice, however is not to be expected, as pure water melts at 0 deg. C. Contamination of the water (salt) may lower this melting point. The freezing of water doesn't have to take place at 0 deg. C. Pure water can be super-cooled at temperatures as low as -40 deg. C before it freezes. Contamination by small particles helps water freezing at higher sub-zero temperatures. Agitating super-cooled water is also a means of freezing it instantly.
Neither, -2 is less than 0 (aka lower)
At 1 atmosphere of pressure, the boiling point of water is 100 degrees Celsius (Centigrade). The volume of water does not matter.

We require to superheat the refrigerant to ensure that no liquid enters in the compressor.So in most of the cases degree of superheat is kept 2 to 3 deg c
Thaw it in a refrigerator or cooler at the temp range of 2 to 4 degree centigrade for 12 hours.
By cooling it below 4 degrees centigrade whereupon its density will decrease. By heating it above 4 degrees centigrade whereupon its density will decrease. Water is at its densest at about 4 degrees centigrade.
2ºC = 35.6ºF

Sub-zero is anything that is less than zero. That means that-1 degree, -2 degrees, -3 degrees, etc. are all 'sub-zero'. To be complete, you also have to specify whether you are talking centigrade or Fahrenheit. When centigrade, it just means the same as below freezing (0 degrees centigrade). When Fahrenheit, sub zero is starting to be seriously cold since freezing is +32 degrees Fahrenheit.
Polynomials are classified by their degree as follows: Constant (degree 0) - a single value (e.g., 5). Linear (degree 1) - of the form ( ax + b ) (e.g., ( 2x + 3 )). Quadratic (degree 2) - of the form ( ax^2 + bx + c ) (e.g., ( x^2 - 4x + 4 )). Cubic (degree 3) - of the form ( ax^3 + bx^2 + cx + d ) (e.g., ( x^3 + 2x^2 - x + 7 )). Quartic (degree 4) - of the form ( ax^4 + bx^3 + cx^2 + dx + e ). Quintic (degree 5) - of the form ( ax^5 + bx^4 + cx^3 + dx^2 + ex + f ). Degree 6 (sextic) - of the form ( ax^6 + bx^5 + cx^4 + dx^3 + ex^2 + fx + g ). Degree 7 (septimic) - of the form ( ax^7 + bx^6 + cx^5 + dx^4 + ex^3 + fx^2 + gx + h ). Degree 8 (octic) - of the form ( ax^8 + bx^7 + cx^6 + dx^5 + ex^4 + fx^3 + gx^2 + hx + i ). Degree 9 (nonic) - of the form ( ax^9 + bx^8 + cx^7 + dx^6 + ex^5 + fx^4 + gx^3 + hx^2 + ix + j ). For degrees beyond 9, the naming continues with the corresponding Latin prefixes (decadic for degree 10, undecadic for degree 11, etc.).
The triple point of water is zero degree Celsius this is because 1)zero degree Celsius is the melting point of ice. 2)water changes from liquid to solid in zero degree Celsius.
If you mean in Fahrenheit, it is 36°F.
