Work = force times distance
10*10=100
100J of work done
Answer:
because of the idea that like charges get repulsion as a force.
Explanation:
because you wrap the ball with foil, the negative charges will leave the foil and go into the ball by induction. This leaves the foil as a positively charged particle since its electrons left it for the ball, making the ball a negatively charged particle. but if you bring the negative charge near the foil, the electrons will transfer from that and go into the foil, making it negatively charged. Now, because the ball and the foil have the same charge, they repel. the foil flies off.
Answer: The boiling point of solution is
Explanation:
Elevation in boiling point:
where,
= boiling point of solution = ?
= boiling point of toluene =
= boiling point constant of toluene =
m = molality
i = Van't Hoff factor = 1 (for non-electrolyte)
= mass of solute = 7.94 g
= mass of solvent (toluene) = 69.2 g
= molar mass of solute = 254g/mol
Now put all the given values in the above formula, we get:
Therefore, the boiling point (in °C) of a solution is 112.16
