The type of physical change that can always be reversed by heating or cooling is : Melting

Melting is a process of transforming solid substance into liquid , usually done by heating. The thing is , this process usually can be reverse by cooling the liquid result back into solid form

hope this helps

Explanation:

Changes that do not lead to any change in chemical composition of a substance is known as a physical change.

For example, melting point, boiling point, density, volume are known as physical changes.

Melting is a property in which a substance changes from solid state to liquid state.

For example, melting of ice is a physical change which can be reversed by cooling the substance again.

Therefore, we can conclude that melting is a physical change that can always be reversed by heating or cooling.

We measure the loudness of sound in decibels.<br> a. True<br> b. False
Tatiana [17]

Answer: The correct answer is True.

Explanation:

Loudness of sound is referred to how soft or loud a sound is for the listener.

This term is measured in a unit known as decibels referred to as dB.

This unit is used to measure the relative intensity of sounds on a scale from zero to 100 dB.

More the value of decibels, it will be uncomfortable for a person to hear that sound.

So Yes, the loudness of sound is measured in decibels.

Beta emission, alpha emission, positron emission, and electron capture are processes that result in a change in atomic number. W
Tema [17]

Alpha emission is the process results in a change in mass number. Option B is correct.

<h3>What is mass number?</h3>

The total number of protons and neutrons in an atomic nucleus is known as the mass number, often known as the atomic mass number or nucleon number.

It's about the same as the atom's atomic mass, expressed in atomic mass units.

The alpha particle is a helium nucleus with two protons and two neutrons in an alpha decay or alpha emission. The number of protons and neutrons is reduced by two as a result of this action.

The quantity of protons and neutrons is affected by gamma emission descent. Also, while electron capture has no effect on the number of neutrons, it does raise the 1 also number of protons by one.

Alpha emission is the process results in a change in mass number.

Hence option B is correct.
