Magma and lava are words that are used in relation to rock formation. Magma refers to melted rock, that is rock in liquid form, which is found in the earth's crust. The lava on the other hand to the magma which has escaped from the earth crust and has moved to the surface via volcano vent. Thus. magma and lava both refer to molten rock, but magma refers to the molten rock that is found underneath the earth while lava refer to the molten rock that is found on the earth surface; that is the difference between them.
Answer : The boiling point of water increases, 
Solution : Given,
Moles of solute (sugar) = 4 moles
Mass of solvent (water) = 1 Kg
i = 1 for sugar
Formula used :
Where,
= elevation in boiling point
= elevation constant
m = molality
= moles of solute (sugar)
= mass of solvent (water)
i = van't Hoff factor
Now put all the given values in this formula, we get the elevation in boiling point of water.
Therefore, the elevation in boiling point of water is
The prefix di- means that there are two nitrogens.
Just like in carbon dioxide (CO2) there is one carbon and two oxides
Answer:
C.
Milk boils at about 212°F (100°C).
Explanation:
The boiling point is a physical property of every matter. Physical properties tell us what a substance is when no change is occuring to its constituents. Such properties can be observed with our senses or instruments or pieces of apparatus.
Some examples of physical properties are colour, taste, odour, hardness, texture, solubility in water.
They all depict what typifies a matter when no change whatever is imparted on them.
