So dew point is temp at which the temperature gives up its moisture, and relative humidity is the percentage of moisture a temperature can hold if its totally saturated, maybe I got it wrong
Pretty close except relative humidity doesn't need to be totally saturated. I believe total saturation would be 100% relative humidity. So as I mentioned in the video the hotter air is the more moisture it can hold as a general rule. So it's how humid the air is relative to how much moisture the air can hold. I hope that makes sense. And thank you for your comment I hope the video was informative :)
