Question

How is the mass of a liquid substance affected after it boils.

Answer 1

The mass of a liquid substance affected after it boils : C it stays the same

Explanation:

Matter

Anything that occupies space and has mass .

The states of matter are :

Solids

Liquids

gases

Interconversion of state of matter

Solid ------liquid -----------Gas

    (on heating )   (on heating )

• One state can be changed in to another by changing the condition of temperature , pressure etc .
• When liquid is boiled , it gets converted to gaseous form on heating .The heat supplied to change the state of matter is called latent heat .
• This latent heat , just helps in increasing the spaces between particles and decreasing the forces between them Hence we can say that it helps in changing  the state .But it doesn't change the mass .Hence mass of substance remains the same .
• Similarly , gas ----->  liquid -----> solid
