WebNov 21, 2024 · WHAT IS K-VALUE? K-Value represents the thermal conductivity of a material, and it measures its ability to conduct the heat. So, the lower the K-value, the better the insulation is. WHAT IS U-VALUE? U-Value measures the thermal transmittance of materials as the rate of transfer of heat through matter. WebJan 30, 2024 · A large Ka value indicates a stronger acid (more of the acid dissociates) and small Ka value indicates a weaker acid (less of the acid dissociates). For a chemical equation of the form HA + H2O ⇋ H3O + + A − Ka is express as Ka = [H3O +][A −] [HA] where HA is the undissociated acid and A − is the conjugate base of the acid.
