What will happens if you mix flour and water?

What will happens if you mix flour and water?

Flour and water can be mixed together to produce a thickener, a paste or a batter. The end result of mixing flour and water depends on the ratio of flour to water as well as on the temperature of the flour and the water.

Can we still see the flour after mixing it with water?

when flour is mixed with water, it forms a mixture known as a suspension. Suspensions are generally opaque and forms when the solute (the flour) cannot completely dissolve in the solvent (the water).

Why kneading of dough is an irreversible change?

Making of dough is a reversible change. Baked roti cannot be changed back into the original ball of dough i.e. this change can’t be reversed. Hence, it is an irreversible change.

Is flour and water a reversible change?

Explanation: Making a dough is a reversible change while making a chapati is an irreversible change. Explanation: Mixing flour and water would be a physical change, since neither the water nor the flour are changing their chemical makeup.

Is an example of irreversible change?

Burning. Burning is an example of an irreversible change. When you burn wood you get ash and smoke. You cannot change the ash and smoke back to wood again.

What objects are reversible?

Reversible changes are changes that can be undone or reversed. Melting, freezing, boiling, evaporating, condensing, dissolving and also, changing the shape of a substance are examples of reversible changes.

Is Melting Chocolate reversible or irreversible?

Melting is a reversible change. If a block of chocolate melts, it can be frozen again to make an identical block of chocolate. Other changes are permanent: it is impossible to get back to the starting point. These are called irreversible changes.

Is Melting Chocolate a reversible reaction?

An easy experiment to do is melting chocolate, which helps to practically exhibit the first phase of a reversible change.

Why cooking an egg is not reversible?

Cooking an egg is an irreversible change. The cooked egg cannot be turned back into a raw egg. The chemicals that make up the egg have been changed by cooking to make new substances. There is only a change in the state of matter and no chemical change has occurred and it is a reversible change.

Is melting a candle reversible?

Physical/reversible changes: Melting of the candle wax is a physical/reversible change. The burning of candle wax to form hydrocarbons is a chemical change.

Is melting of candle wax a permanent change?

Melting of wax is temporary and wax can settle again on cooling and turns into a solid. Hence, the change is only physical and the state of matter changes. Burning of the candle is permanent because once it is burnt it cannot be converted into the candle.

Is melting of candle wax a chemical reaction?

Physical Changes: On heating, candle wax gets melted. Since it again turns into solid wax on cooling. So, the melting of wax and vapourisation of melted wax are physical changes. Chemical Changes : The wax near flame burns and gives new substances like carbon dioxide, carbon soot, water vapour, heat and light.

What is the difference between melting of candle and burning of candle?

Melting of wax is physical change because only physical state is changing from solid to liquid but burning of wax is chemical change because in burning, wax reacts with oxygen present in surroundings and forms carbon di oxide and ash.

Why is melting a candle a physical change?

Melting of wax( due to heat) is a physical chage that occurs prior to the oxidation. The candle is a physical change because when a candle burns, the wax melts. The wax undergoes a change of state from a solid to a liquid when given heat, but no new substance is formed during the process.
