States of Matter Questions

Multiple choice

Change from a liquid state to a solid state

  1. Freezing

  2. Melting

  3. Addition of heat

  4. Thermal energy
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Freezing is the phase transition where a substance changes from a liquid to a solid. Melting is the reverse process, while addition of heat and thermal energy are concepts related to energy transfer rather than the state change itself.

Multiple choice

Particles slow and turn from a gas to a liquid

  1. spontaneous combustion

  2. Condensation

  3. vaporization

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Condensation is the process where gas particles lose energy, slow down, and transition into a liquid state. Vaporization is the opposite process where a liquid turns into a gas.

Multiple choice

matter that has a definite volume but no definite shape

  1. A CAT!!

  2. Gas

  3. Plasma

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

A liquid has a definite volume because its particles are close together, but it takes the shape of its container because the particles can slide past each other. Gases have no definite shape or volume, and solids have both.

Multiple choice

Anything that takes up space and has mass 

  1. Solid

  2. Liquid

  3. Matter

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

Matter is defined as anything that has mass and takes up space (volume). Solids, liquids, and gases are all specific states of matter.

Multiple choice

Souring of milk is what?

  1. Chemical Change

  2. Physical Change

  3. Physical Property

  4. Chemical Property

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The souring of milk is caused by bacteria producing lactic acid, which changes the chemical composition of the milk. This is a classic example of a chemical change.

Multiple choice

Which state of matter has the most energy?

  1. Solid

  2. Liquid

  3. Gas
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Particles in a gas have more kinetic energy than those in a liquid or solid, allowing them to move freely and fill their container.

Multiple choice

Wax that is water insoluble is removed by using a ___.

  1. water soluble lotion

  2. oil based solution

  3. warm water

  4. salt water
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Water insoluble wax cannot be removed with water; it requires an oil based solution to dissolve the wax residue from the skin. Water soluble waxes are the only type that can be removed with water.

Multiple choice

Using the blend modality, the application of thermolysis causes the lye to:

  1. coagulate

  2. become more porous

  3. become less turbulent

  4. become more caustic
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

In the blend modality, the heat from thermolysis increases the chemical reaction rate of the lye (sodium hydroxide) produced by the galvanic current, making it more caustic and effective at destroying the hair follicle.

Multiple choice

Pitta is a combination of what two elements?

  1. air and ether

  2. earth and water

  3. fire and water

  4. air and earth
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

In Ayurveda, the Pitta dosha is governed by the elements of fire and water. These elements are responsible for transformation, metabolism, and digestion in the body.

Multiple choice evs sources of water and water cycle groundwater and depletion of water table rain: where does it come from availability and forms of water the water cycle

Which of the following is not naturally occurring form of water?

  1. Solid

  2. Liquid

  3. Vapour

  4. Semi-solid
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Water exists in liquid form upto  $100^0$C , at 100$^0$C it exists as vapour and at 4$^0$C it exists in solid form  as ice. So water exists in all the states or forms except semisolid, jelly state

So, the correct answer is 'Semi-solid'
