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
Answer:
The potential energy is 9800 J.
Explanation:
given information:
mass, m = 50 kg
height, h = 20 m
to calculate the potential energy, we can use the following formula
PE = mgh
where
PE = potential energy (Joule)
m = mass (kg)
h = height (m)
g = gravitational constant (9.8 m/s²)
so,
PE = mgh
= 50 x 9.8 x 20
= 9800 J
