In a solution, the substance that is dissolved is called blank space

The stuff you dissolve is the SOLUTE.  What you dissolve it IN is the SOLVENT.

The substance which gets dissolved in a solution is called as the Solute.

Explanation:

The solution consists of two parts, namely, one is solute and the other is solvent. The solute is the particles of the matter which gets dissolved. The solvent is the particle of the matter which dissolves the other particle. Or simply say, solvent dissolves the solute in a solution.

The saturation of the solution is determined by the capacity of solute dissolved in the solvent, which makes a solution either saturated, unsaturated or supersaturated solution.

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
