If the sample holder is left open during the absorbance measurement of volatile solutions, 1 the value of measured absorbance will be higher than the expected value. Select one: True False Pressure and temperature of a gas are 2 a. No definite relationship b. Exponentially related c. Inversely proportional d. Directly proportional In an open container the water level decreases over time, Why ? a. The container absorb the amount of water b. Rate of evaporation is less than rate of condensation C. Rate of evaporation is larger than rate of condensation d. Water level should remain constant Methyl red is considered a weak organic acid Select one: O True O False If the sample holder is left open during the absorbance measurement of volatile solutions, 1 the value of measured absorbance will be higher than the expected value.
