When food gets spoiled by micro organisms, it produces a foul smell. By the action of the enzymes released by these microbes, the components of the food undergo chemical changes. Due to this, the food emits foul smell. It is a permanent change and irreversible in nature.

1. False: Two objects cannot occupy the same space at the same time.

2. False: When kerosene and water are mixed together, kerosene will form the upper layer.

3. True

4. True

5. False: Less viscous liquids flow easily.

6. False: Liquids have a definite volume.

7. False: Gases can be compressed easily.

8. False: It is easier to walk through air than water.

9. False: Water freezes at 0 °C

10. True

11. False: The rate of evaporation is affected by change in humidity (i.e., it decreases with increase in humidity).

When kerosene and water are mixed, kerosene forms the upper layer as it has less density than water.

1. Sugar: Others are liquids.

2. Oil: Others are solids.

3. Mercury: Others are gases.

4. Water: Others are sublimatory substances.

(c) less than 90

Centrifugation is the method used. This is a method for separating components from a mixture, based on the difference in the mass of particles. This method is used in clinical laboratories to separate blood cells from blood samples and also for separation of butter from curd.

Correct answer is (c) greater

According to Bernoulli’s theorem for horizontal flow P + 1/2 pv² = constant. As speed of water between the ships is more than outside them pressure between them gets reduced & pressure outside is more so the excess pressure pushes the ships close to each other therefore they get attracted.

Hot water soap solution has small surface tension therefore can remove the dirt from clothes by wetting them effectively.

Answer is Chromatography

(d) area of the liquid surface

(b) more if situated near the bottom

The battle of Khanwa was fought in March, 1527 CE between Babur and Maharana Sanga and Babur followed his Tuluguma system in this battle.

Pressure exerted by a liquid column of height h, P = hρg. As A is large, so P is quite large. Due to it the bottom are made thick.

The molecules in a liquid surface have a net downward force (cohesion) on them, so work done in bringing them from within the body of liquid to the surface increases surface energy.

a. Rate of diffusion is more in gaseous state, less in solid state.

b. Rate of diffusion increases with increase in temperature.

c. The smell of hot food material spread quickly.

The atmospheric pressure is low at high altitudes. Due to greater pressure difference in blood pressure and the atmospheric pressure, it is difficult to stop bleeding from a cut in the body.

Pressure exerted by liquid column = hpg so as ‘h’ increases p increases so to with stand high pressure dams are made thick near the bottom.

a. Separating funnel 

b. Petrol and kerosene are miscible liquids. 

c. Fractional distillation

The contract for the invasion of Chittor was held at Champaner by the joint army of Gujarat and Malwa.

The first battle of Tarain was fought in 1191 CE between Prithviraj Chauhan and Muhammad Ghori.

French traveller Bernier wrote his travel account in the form of famous book “Travels in the Mughal Empire’.

On 23 October, 1567 CE during the reign of Maharana Udaisingh of Mewar, Akbar attacked the Chittor fort.

Answer is Chromatography

The density of sea water is more than the density of river water, hence sea water gives more up thrust for the same volume of water displaced.

a. by picking 

b. centrifugation 

c. filtration 

d. distillation
