They used an interferometer to measure the amount of ozone in the atmosphere.

Explanation

• A Homogeneous mixture has the same proportion of its compound in a sample.
  • Sugar in water is a homogeneous mixture.
• A Heterogeneous mixture has a different proportion of its compound in a sample. 
• A Mixture in which a solute particle does not dissolve, but gets suspended is a suspension.
• A solution in which the substances are regularly suspended in a fluid is a Colloidal Solution.
• A true solution is a homogeneous mixture of two or more substances in which the substance dissolved in the solvent has a particle size of less than 10-9 m or 1 nm.

Explanation

• Sugar (a solid) dissolves in water (a liquid) to form a solution, making it a classic example of a solid-liquid solution.
• The sugar molecules (solute) are dissolved in the water molecules (solvent), resulting in a homogeneous mixture.

Explanation

The fog in winter is caused by a combination of:
