Would you add a small bar of soap of the same volume of soap powder to some water when washing clothes?
No, you cannot use bar soap in place of powdered soap when washing clothes - unless you are washing by hand. Powdered and liquid soaps are designed to disperse quickly into the wash water, bar soaps will not do that. After the washing process, bar soap may remain as a bar (although a bit smaller) and then the rinse steps will not be effective at removing residual soap.

Does liquid soap break fat faster than bar soap?
Liquid soap is made to mix with water faster than bar soap. Therefore can break up the molecules of fat faster. However if bar of soap was swished about in very hot water it would form a washing up water just about equal to the liquid soap. This was the way we did it in the 1930's using a small wire basket just big enough to take the bar of soap.
