Which of the followin separation methods is used in making coffee at home ? chromatography filtration - i think it’s this one fractional distillation simple distillation

Filtration

Explanation:

Chromatography : It is a type of separation process in which the liquid or gas is separated into components at different rate.

Filtration : It is a type of mechanical separation process in which the solid is separated from the liquid through the filter paper. The beans which are larger in size remain as such and the the coffee passes through the filter.

Fractional distillation is a process by which components in a chemical mixture are separated into different parts called as fractions according to their different boiling points.

Simple Distillation : It is a type of separation process in which the mixture of liquid separated or evaporated at different temperatures.

where are the choice options?

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
