does yeast need to be in an liquid solution to work? I mean can it work if mixed in with a solid compound like pure sugar? rather than diluting the sugar first in water then addin in the yeast

Saccharomyces cerevisiae (yeast) requires a water activity (Aw) of about 0.80. Pure sugar would not provide that.

Very few things (including yeast) can actually grow in pure sugar. Almost all living things, including yeast, need some fluid in which to grow.

Yeast does need to be in water. Dissolve it in warm water, not hot. You can test it like a baby bottle. if you feed it a teaspoon of sugar it will grow faster. Usually it is worked into a flour mixture, but it does need the water.
