1st
R - evaporation (liq to gas)
S - condensation (gas to liq)
—> Both R and S involve change of state of water

Q - from clouds to rain, the condensed water droplets (liq) form BIGGER water droplets (still liq), which eventually fall as rain (still liq)
—> Q does NOT involve change of state of water (remains liq)
