Hey there!
The correct answer to your question is option A.
The result of adding more solute to a solution is the boiling point increases.
Another name of the boiling point increasing is "Boiling point elevation".
The reason why solute increases the boiling point is because when the solute is added to the water, the energy increases.
Hope this helps you.
Have a great day!
Answer:
Temperature causes water molecules to move more quickly, because each individual molecule has more energy as it gets hotter. If you get water hot enough, the molecules move so much that the hydrogen bonds that hold them together start to break and the water becomes a gas.
Answer:
Final temperature =
Explanation:
Given that,
Heat added, Q = 250 J
Mass, m = 30 g
Initial temperature, T₁ = 22°C
The Specific heat of Cu= 0.387 J/g °C
We know that, heat added due to the change in temperature is given by :
Put all the values,
So, the final temperature is equal to .
