water,cause coffe or tea would not have the nutrients It needs to grow
You would evaporate the water and there would be dried up coffee powder
Salt Water!
When coffee is added to water, that is a physical change. The coffee does not undergo a chemical reaction, the various chemical constituents of coffee remain the same. What changes is that the coffee is dissolved in water. If the water were to evaporate, leaving the coffee behind, it would be the same as it was (not counting the loss of some volatile constituents which would also evaporate, along with the water) before it was added to water.
I would tend to think red because most plants grow fastest in the morning. Also most school projects for children use red dye and water in a bag.
Caffeine does help a plant grow faster. If you put coffee grinds on some of your plants, it's very healthy for them. Water also helps keep plants alive, so you would still need to do that.
You would get stronger coffee. Also note, you can add Kaluha coffee liqueur to your coffee and get even more coffee flavor. That is actually a better recipe than brewing your coffee with coffee rather than water.
Sugar. Coffee will not disolve in water (though there are some soluble components in coffee that will dissolve out of it - which is why we use it).
At 80C, water would carry sound fastest because the water molecules are in random motion more than water at 25C.
The substance that cools the fastest is milk
Yes, coffee can dissolve. How else would youu make coffee with a coffee pot? Usually coffee takes a while to dissolve in cold water but it will not take long to dissolve in hot water. Made by Olivia Doherty
That would be 84 cups of coffee.
As opposed to pure water? yes. i suppose it could be considered an impurity if you are striving for pure water. But if your goal is to make coffee, and the 2 ingredients you need are hot water and coffee, then no, i would not consider coffee and impurity. In that case, milk, or salt, or murcury, or dog feces would all be considered impurities in your pure cup of coffee. Purity in this case is really a matter of perspective
