P and q are two substances such that melting point melting point of p and boiling point of q are the same.if p is solid at a certain temperature what will q be at that temperature?
Answers
Answer:
Explanation:
The temperature at which solid changes its state to liquid at atmospheric pressure is called the melting point of that liquid. This is the point at which both liquid and solid phase exists at equilibrium. The melting point of the substance also varies with pressure and is specified at standard pressure. The term ‘freezing point’ is used to denote the temperature at which a liquid is converted into a solid and can, therefore, be viewed as the opposite of the term ‘melting point’. However, substances can be cooled
Answer:
If p is solid at a certain temperature then q will be liquid at that temperature.
Explanation:
Given,
The melting point 'p' is equal to the boiling point of 'q'.
The substance 'p' is solid at some temperature.
To find,
The state of matter of the substance 'q' at that temperature.
Concept,
Melting point: The temperature at which the solid substance converts into a liquid substance is known as the melting point.
Boiling point: The temperature at which the liquid substance converts into a gaseous substance is known as the boiling point.
Calculation,
Now let's say the melting point of 'p' and the boiling point of 'q' is 'T'.
But for the substance 'p' to be in solid form the temperature of the body must be less than 'T'
Hence, for the same temperature which is less than 'T,' the substance 'q' exists in liquid form.
Therefore, if p is solid at a certain temperature then q will be liquid at that temperature.
