question
A student poured a solution of bromothymol blue indicator into three test tubes. Then he placed an aquatic plant in two of the test tubes, as shown below. He placed a stopper on each test tube and placed them all in the dark for 24 hours. Bromothymol blue turns from blue to yellow in the presence of CO2
Predict what will happen to the test tubes in Figure 9–9 after 24 hours in the dark.
In the dark the aquatic plant won't do photosynthesis. Instead it will do cellular respiration in which it will produce CO2. Therefore after 24 hours of letting the plant in the dark introducing Bromothymol in the solution will cause it to turn yellow.

than the boiling point of water?
12K is the boiling point of the chemical .
The boiling point of any liquid changes to the applied pressure the normal boiling point is the temperature at which the vapor pressure is equal to the standard sea-level atmospheric pressure .At sea level, water boils at 100° C (212° F).The boiling point of a liquid is the temperature at which its vapor pressure is equivalent to the pressure of the gas above it.
Boiling point is used to identify and classify a given compound. A liquid boils when its vapour pressure is equal to the atmospheric pressure. Vapour pressure is also defined by the kinetic energy of a molecule. Kinetic energy is dependent on the temperature, mass and velocity of a molecule.
