Is coffee added to water an example of chemical change?
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.
What does solute mean in science terms?
A solute is what is dissolved in a solution eg. Salt and water. The solute in the solution is the salt as it has dissolved in water. There can be many different solutes in a solution at one time. A cup of coffee contains many solutes as the coffee granules and the sugar have dissolved in the water, making these two solids solutes.
What is the solvent and solute of coffee?
The solvent is water; the solute is ground roasted coffee beans (in addition to sugar, salt, cream and whatever else you prefer to add)!
What is a solute give example?
a solute is a disolveable substance, for example- salt, which can disvile in a SOLVENT, like water. other solutes include sugar and coffee
Can a liquid dissolve a gas?
There are a number of ways in which a gas could dissolve in a liquid. It could bind with the liquid molecules.
What happened to the instant coffee when it was stirred into the boiling water?
This coffee is dissolved in water.
What do sugar salt dissolving in coffee?
Dissolved in water containing coffee, not in coffee.
Is coffee an impurity?
if dissolved in water, it can be called an impurity.
Does coffee dissolved in cold water?
Somewhat, but it dissolves faster in warm water.
A solute dissolved in a solvent?
If you are looking for examples, here are some: salt water sugar water sodium hydroxide dissolved in water Kool-Aid coffee tea
Why don't coffee grounds dissolve in water?
it doesnt easily dissolved on a cold water because of its temperature
Why does coffee evaporates faster than water?
It doesn't (at room temperature); coffee is primarily water. The one exception is if energy is applied to a container of water and a container of coffee. The dissolved solids in coffee being darker absorb energy faster, heating it quicker, thus evaporating the water within the coffee faster.
Is a powdered coffee a solid?
All powders are by definition solid. Of course, once the coffee powder is dissolved in water, it ceases to be a powder and instead becomes part of the liquid coffee.

What is the difference between the solvent and the solute that make up a solution?
The solute is what is being dissolved. The solvent is what the solute is dissolved in. Take coffee for example. The solute would be the coffee, and the water would be the solvent. In fact, water is able to dissolve so many substances that it's called the universal solvent.
When you add 5ml of sugar to 250ml of coffee the volume is still 250ml?
When sugar is dissolved in coffee, the sugar molecules is fitted inside the empty spaces in the water molecules. This means that the volume of coffee does not increase.
