Answer
For this we use ideal gas equation which is:
P1V1 = P2V2
P1 = 1.10 atm
V1 = 326 ml
P2 = 1.90
V2 = ?
By rearranging the ideal gas equation:
V2 = P1V1 ÷ P2
V2 = 1.10 × 326 ÷1.90
V2 = 358.6 ÷ 1.90
V2 = 188.7 ml
When a solute, sugar in this case, is added, the boiling point of the solution increases. Additionally, the melting point decreases.
To answer your question,
The boiling point of pure water is lower than sugar-water solution.
The melting point is higher for pure water than for sugar-water solution.

Answer: A. The particles move faster
Explanation:
Increasing the temperature increases the kinetic energy of the particles, causing them to move faster.
Answer: gradual increase in temperature of ice from −15°C to 0°C, holding at 0°C as ice melts to water
Explanation: The heat used to convert solid to liquid is gained by molecules to gain kinetic energy and thus the molecules start moving faster and the temperature increases.
But as the melting point is approached i.e.
, the temperature remains constant as now the heat given is used to break the inter molecular forces and thus is not reflected in terms of temperature increase. This hidden heat is called as latent heat.
The temperature remains constant till the phase change is complete.
