Questions Related to matter in our surroundings

Multiple choice chemistry matter in our surroundings atmospheric pressure and boiling point evaporation - factors and effects in daily life changes in physical state - boiling, evaporation and condensation

Which of the following plays an important part while drinking a liquid with a straw?

  1. Humidity

  2. Temperature

  3. Atmospheric pressure

  4. Composition of air
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

When you suck on a straw, stuck into liquid it lowers the pressure in the straw. That makes atmospheric pressure higher than the pressure in the straw which force the liquid to go up into the straw and into your mouth. So, atmospheric pressure plays important role while drinking a liquid with a straw.

Multiple choice chemistry matter in our surroundings atmospheric pressure and boiling point evaporation - factors and effects in daily life changes in physical state - boiling, evaporation and condensation

The air pressure in the balloon is due to the air filled in it, striking the walls of the balloon.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The air in the balloon exerts pressure on the walls of the balloon. This is accordance with the kinetic molecular theory of gases which state that the pressure exerted by the gas is equal to the pressure applied by the gas molecule on the walls of container.

When the atmospheric pressure of the earth falls suddenly then __________.

  1. there is a clear weather

  2. there may be a slow wind

  3. there may be storms and strong winds

  4. none of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Atmospheric pressure acts as an indicator of weather conditions. Sudden decrease in atmospheric pressure of the earth shows that there may be storms and strong winds. Sometimes it can cause rain also.

If the air pressure of an area decreases suddenly then our blood vessels swells up and sometimes bursts.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

If the air pressure of an area suddenly decreases, then in the human body the blood vessels swell up or sometimes bursts. This activity is commonly seen in mountaineers.

Unit measure of atmospheric pressure is equal to the column of mercury pressure of _____.

  1. 76 cm

  2. 76 mm

  3. 1.013 mm

  4. 10.13 mm
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The unit measure of atmospheric pressure is equal to the column of mercury pressure of 76 cm or 760 mm of mercury.

Liquids exert equal pressure on the wall of container at equal depth.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Liquids exert equal pressure on the wall of the container at equal depth. This is because the density of the liquid at the same depth will be same.

Multiple choice chemistry matter in our surroundings diffusion in different states of matter properties of solids, liquid, and gas particle theory of matter

The one characteristic which is similar for solids and liquids and not gases is:

  1. fixed shape

  2. fixed volume

  3. both of these

  4. none of these
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Both solids and liquids have a fixed volume but gases do not have a fixed volume. This is because liquids and solids have strong intermolecular forces of attraction compared to gases.

A distinctive property of the liquid state is____________.

  1. compressibility

  2. rigidity

  3. condensation

  4. surface tension
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

A distinctive property of the liquid state is surface tension, leading to wetting phenomena. Surface tension is the elastic tendency of a fluid surface which makes it acquire the least surface area possible. At liquid-air interfaces, surface tension results from the greater attraction of liquid molecules to each other (due to cohesion) than to the molecules in the air (due to adhesion).

The top of liquids have a flat surface because _____________.

  1. pressure

  2. temperature

  3. gravity

  4. volume
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The top of a liquid will usually have a flat surface. That flat surface is the result of gravity pulling on the liquid molecules. If you put an ice cube (solid) into the cup, it will sit there and not change shape. As the cube warms and melts, the liquid water will fill the bottom of the cup and have a flat surface on top.
