As a rule of thumb, your vol. should not be above 2/3 of total capacity of the flask. Do a back calculation for 75 mL EtOH, use ~150 ml capacity and above but try not to use too large boiling flask. I will stay say between 150-250mL.
The boiling point of ethanol would be lower at high altitudes compared to sea level. This is because the atmospheric pressure is lower at high altitudes, which requires less heat to reach the boiling point of a liquid like ethanol.
Yes, gas was likely released in the flask with the boiled yeast mixture due to the fermentation process. Yeast metabolizes sugars, producing carbon dioxide and ethanol as byproducts. If the mixture was not completely killed during boiling, any remaining viable yeast could still ferment available sugars, causing gas to form. However, if the yeast was entirely killed during boiling, no gas would be produced.
To distill aniline at 100 degrees Celsius, you would need to apply vacuum distillation. By lowering the pressure in the distillation setup, you can decrease the boiling point of aniline, allowing it to vaporize and distill at a lower temperature, such as 100 degrees Celsius. This technique is commonly used to separate compounds with high boiling points under milder conditions.
The solid material left behind in the distillation process would typically be found in the distillation flask or boiling flask after the distillation is complete. This solid residue results from the separation of components in the mixture and is often referred to as the distillation residue or distillation bottoms.
A flat bottom flask would be an Ehrlemeyer flask, which is used quite a lot by chemists.anf
Ethanol would because it has a boiling point of 78.4 C where as water has one at 100 C.Through this process breweries and wineries can distill their liquors and find the percent off ethanol (alcohol) by volume.
The boiling point of ethanol would be lower at high altitudes compared to sea level. This is because the atmospheric pressure is lower at high altitudes, which requires less heat to reach the boiling point of a liquid like ethanol.
The exact pressure would vary dependant on if you are referring to the boiling point of an ethanol azeotrope or absolute ethanol. For example the boiling point at 1 ATM for azeotropic ethanol is 78.15C and for absolute ethanol it is 78.4C. At a temperature of 35.0C azeotropic ethanol will boil in a vacuume pressure of 159.8 mbar/hPa or 119.9 mmHg/Torr where as absolute ethanol boils at a slightly lower pressure of 158.6 mbar/hPa or 119 mmHg/Torr.

Fractional distillation can be used to separate ethanol from a mixture of ethanol and propanol. This technique takes advantage of the differences in boiling points of the two compounds to separate them based on their vapor pressures. Ethanol has a lower boiling point than propanol, allowing it to vaporize first and be collected separately.
Ethanol is a liquid at 100 degrees Celsius, as its boiling point is 78.37 degrees Celsius. At 100 degrees Celsius, ethanol would be in its gaseous state.

To change C to K just add 273.01 to the C temperature (78.3 C = 351.3 K) You might think it is 351. 31 K but the original temperature was only accurate to one decimal place.
Ethanol is a liquid at 100 degrees Celsius. It boils at 78.4 degrees Celsius, so at 100 degrees Celsius it would be in a gaseous state if it were heated beyond its boiling point.

the green pigment, chlorophyll should be removed in order to observe color change during test for starch. in order to do that, the leaf is dipped in boiling water to break cell walls which would facilitate the release of the pigment out of the cell. immersion in ethanol would dissolve the pigment which would be released out of the cells thereby making the leaf appear pale in color.
I the flask was sealed, the air inside of the flask would take up less space and as a result, cause a drop in pressure inside the flask.
