44:17 TEA [Homogeneous Mixture] The resulting mixture looks uniform because the dispersed particles or molecules are too small to be seen individually. There are no visible layers or separate phases.When you taste the tea, the uniform distribution of the components means that each sip contains the same proportions of water, milk, tea compounds, and sugar. This is why it tastes the same throughout.
44:17 DOUBT QUESTION In our previous discussion about matter, we learned that matter is composed of particles. When a substance, like sugar, is dissolved in another substance, such as water, the sugar particles separate and spread among the water molecules. In this chapter, we are studying the chemical properties of matter. You have explained that mixtures are substances made up of two or more elements and compounds that are not physically combined. You have also explained that homogeneous mixtures are those mixtures in which substances are mixed and are indistinguishable from one another. An example of a homogeneous mixture is tea, which is made up of various constituents (like tea leaves, sugar, milk, ginger, and some other ingredients). So, can we say that the tea constituents have separated into intermolecular spaces between the water molecules? When preparing tea, heat is absorbed or released, but a mixture doesn't require any heat for its formation. Since a homogeneous mixture is also a type of mixture, why are we considering a homogeneous mixture as a mixture?
Bro this question is kinda dumb but since it's a doubt lemme clear it for you bro we know a mixture consists of more then 1 type of element and let us take the example of tea we have various solvent and if you have ever had 1 you should know that ginger never dissolve and we need extra heat to make tea ik it's dumb but according to me the particles of the constituent of the tea never dissolve in intermolecular spaces and bro it's just an example why are you taking it so seriously but still if possible I would ask from my teacher and let you know if you want
