If a substance has a low absorption, will its transmittance be high or low

Well, it is important to note that the measurements for absorption and transmittance are inversely related, a low absorption means the substance was not as effective in scattering and or absorbing the specific wavelength of light, I assume, and that most of the wavelength of light has passed through the substance and or has been transmitted, thus it would have a high transmittance.

Evaporation: this is when warmth from the sun causes water from oceans, lakes, streams, ice and soils to rise into the air and turn into water vapour (gas). water vapour droplets join together to make clouds! condensation: this is when water vapour in the air cools down and turns back into liquid water.
