Total no. Of matches=Total no. Of team - 1 = 24-1=23 Total no. Round =2*2*2*2*2 i.e. Digit 2 report 5 times =5 rounds So total no. Round=5 round Total team in upper half=Total no. Of teams=24/2=12 teams As the total no. Of teams are more than 16 so we have to divide teams also in quarter . Teams in each quarter:24/4 =(Q=6) and R=0 Total No. bye=next power of two-total no. Of team =32-24=08 byes Bye in upper half=8/2=4 Bye in lower half =8/2=4

The kelvin is the base unit of temperature in the International System of Units (SI), having the unit symbol K. The relation between kelvin and celsius scales is TK = t°C + 273.15. On the Kelvin scale, pure water freezes at 273.15 K, and it boils at 373.15 K. It is named after the Belfast-born Glasgow University engineer and physicist William Thomson, 1st Baron Kelvin (1824–1907).

Celsius relates to, the Celsius temperature scale (previously known as the centigrade scale). The degree Celsius (symbol: °C) can refer to a specific temperature on the Celsius scale as well as serve as unit increment to indicate a temperature interval(a difference between two temperatures or an uncertainty). “Celsius” is named after the Swedish astronomer Anders Celsius (1701-1744), who developed a similar temperature scale two years before his death. K = °C + 273.15 °C = K − 273.15 Until 1954, 0 °C on the Celsius scale was defined as the melting point of ice and 100 °C was defined as the boiling point of water under a pressure of one standard atmosphere; this close equivalence is taught in schools today. However, the unit “degree Celsius” and the Celsius scale are currently, by international agreement, defined by two different points: absolute zero, and the triple point of specially prepared water. This definition also precisely relates the Celsius scale to the Kelvin scale, which is the SI base unit of temperature (symbol: K). Absolute zero—the temperature at which nothing could be colder and no heat energy remains in a substance—is defined as being precisely 0 K and −273.15 °C. The triple point of water is defined as being precisely 273.16 K and 0.01 °C.
