Explain why the boiling point is the temperature when the bubbles stop exiting glass bell.
Explain why the boiling point is the temperature when the bubbles stop exiting glass bell.
Liquid water at room temperature is placed in a syringe, which is then sealed. The plunger of the syringe is drawn back, and at some point bubbles of H2 O vapor are formed. Explain why we can state that the water is boiling.
During the microscope boiling point determination of an unknown liquid, heating was discontinued at 154°C and the liquid immediately began to enter the inverted bell. Heating was begun again at once, and the liquid was forced out of the bell. Heating was discontinued at 165°C, at which time a rapid stream of bubbles emerged from the bell. On cooling, the rate of the bubbling gradually diminished until the liquid reached a temperature of 161°Cand entered and filled the bell. Explain...
Explain why the boiling point of a two-component mixture rises slowly throughout a simple distillation when the boiling-point differences or not large
Question 14 1 pts Why is the boiling point of an aqueous solution higher than the boiling point of pure water? Because the temperature increases Because the liquid/gas equilibrium slope is positive on the phase diagram Because the total pressure decreases due to the solute o Because the vapor pressure decreases due to the solute None of the options explain why the boiling point increases
explain why molality is used for boiling-point elevation and freezing-point depression calculations and molarity is used in osmotic pressure calculations.
Explain why acetic acid has a higher boiling point than ethyl alcohol ?
Explain why aldehydes and ketones have a higher boiling point than the corresponding hydrocarbons.
Why does the water in the earthenware container stop boiling as soon as the pot is removed from the fire, and in the metal vessel it boils for a while?
