Look at the list and find out how many substances are insoluble in water?

[Sugar, Soap, Powder, Salt, Stones, Rice]
Detailed Solution for Test: Water - 2 - Question 13

The correct option is Option A.

Sugar dissolves in water because energy is given off when the slightly polar sucrose molecules form intermolecular bonds with the polar water molecules.

Water and oil are very different in their polarity and are therefore insoluble in each other. Because of the two different parts of the molecule, a soap molecule is soluble in water and at the same time can dissolve fats.

Generally, powders tend to become more soluble in water at higher temperatures. Water is a polar solvent, meaning that its electron density is uneven. Nonpolar powders are insoluble in water. Powders composed of large molecules are insoluble in water due to their larger particle size.

Water can dissolve salt because the positive part of water molecules attracts the negative chloride ions and the negative part of water molecules attracts the positive sodium ions. The amount of a substance that can dissolve in a liquid (at a particular temperature) is called the solubility of the substance.

Rock particles are quite bundled up together. So, it is very difficult to get the water particles smudged in there and let them two mix together. The rocks dissolve in water at a very low rate.

Sucrose being a simple molecule, easily dissolves in water. But rice grains have huge and fibrous carbohydrates called starch. That starch is insoluble in water. You can break down the starch, make it simpler which will make it soluble.

Water that is not in motion and is still at one place is called __(41)__ water. Stagnant water is the breeding ground for various insects and __(42)__.These mosquitoes, when bite humans, result in the malaria __(43)__. Stagnant water is more prevalent in the rainy seasons.
Detailed Solution for Test: Water - 2 - Question 14

To fill in the blanks, we need to choose the suitable option that describes water that is not in motion and is still at one place. Let's analyze the options given:
A: Running
- Running water refers to water that is flowing or in motion, which is the opposite of what is described in the sentence.
B: Stagnant
- Stagnant water is the correct option as it refers to water that is not moving and is still at one place.
C: Sitting
- Sitting water is not a commonly used term to describe water. It does not accurately convey the meaning of water that is not in motion.
D: None of these
- Since option B (Stagnant) is the suitable choice, option D (None of these) can be eliminated.

- Water that is not in motion and is still at one place is called stagnant water.
- Stagnant water is the breeding ground for insects and mosquitoes.
- Mosquitoes can transmit diseases like malaria when they bite humans.
- Stagnant water is more common during the rainy seasons.

The density of an object determines whether it will float or sink in another substance. An object will float if it is less dense than the liquid it is placed in. An object will sink if it is more dense than the liquid it is placed in. For instance a candle floats and a clay sinks even though the candle is heavier than the piece of clay. It?s not the weight of the object but, its density compared to the density of water that determines whether an object will sink or float in water.

Q. Which of the following determines whether an object will float or sink?
