Question

what is science ?
and what is solution and exmaple?

Answer 1

a solution is a type of homogeneous mixture that is made up of 2 or more substances.a homogeneous mixture is a type of mixture with uniform composition.this means that the substances cannot be distinguished easily from each other

eg salt and water,sugar dissolved in water

Answer 2

${\underline{\underline{\bf{ What\:is\: Science?}}}}$

Science, any system of knowledge that is concerned with the physical world and its phenomena and that entailsb unbiased observations and systematic experimentation. In general, a science involves a pursuit of knowledge covering general truths or the operations of fundamental laws.

${\underline{\underline{\bf{ What\:is\: Solution:}}}}$

A solution is a homogeneous mixture of two or more substances. You come across various types of solutions in your daily life. Lemonade, soda water etc. are all examples of solutions. Usually we think of a solution as a liquid that contains either a solid, liquid or a gas dissolved in it. But, we can also have solid solutions (alloys) and gaseous solutions (air). In a solution there is homogeneity at the particle level. For example, lemonade tastes the same throughout. This shows that particles of sugar or salt are evenly distributed in the solution.

Examples:

• (i) A solution of sugar in water is a solid in liquid solution. In this solution, sugar is the solute and water is the solvent.

• (ii) A solution of iodine in alcohol known as 'tincture of iodine', has iodine (solid) as the solute and alcohol (liquid) as the solvent.

• (iii) Aerated drinks like soda water etc., are gas in liquid solutions. These contain carbon dioxide (gas) as solute and water (liquid) as solvent.

• (iv) Air is a mixture of gas in gas. Air is a homogeneous mixture of a number of gases. Its two main constituents are: oxygen (21%) and nitrogen (78%). The other gases are present in very small quantities.
