As of my last knowledge update in October 2023, the fastest 2x2 cube solver is Maciej Czapiewski, a Polish speedcuber. He set the world record for the 2x2 single solve with a time of 0.49 seconds at the 2023 World Cube Association (WCA) competition. Speedcubing records can change frequently, so it's always a good idea to check the latest from the WCA or official speedcubing news sources for the most current information.
black. it absorbs more light so it gets warmer
solubility generally increases on heating. so sugar cube in boiling water will dissolve fastest.
A black cup would make the ice-cube melt the fastest becauseblack substances trap in more heat than any other color.
a ice cube in alcohol would melt fastest because of the heating molecules contracting with the ice cube molecules
To make a sugar cube dissolve at the fastest rate, crush or break it into smaller pieces to increase the surface area in contact with the liquid. Stir the liquid consistently to help dissolve the sugar particles more efficiently. Using hot liquid, such as hot water, will also speed up the dissolution process.
sanjai- 1.63 seconds
from Indian who is the fastest century maker in one day international matches?
Fastest to date was Felix Zemdegs in 5.66 seconds.
· ice cube maker
i think 6 seconds ---------- probably unknown, except for the one who did it him/herself. since one possible combination for the cube only requires a single turn to solve the cube, i'd imagine it's somewhere between 0-2 seconds. The fastest Official World Record (with a proper scramble, not a 1-2 turn move) is 5.66 by Feliks Zemdegs.
