C.
Because the amount of energy in the products is less than that of the reactants, the reaction is endothermic. Endothermic reactions use up, or absorb energy.
The amount of salt added to water does not affect the boiling point ot would stay at 100 degrees c or 212 degrees F

Answer:
T₁ = 563.19 K
Explanation:
Given data:
Initial volume = 359 mL
Final volume = 269 mL
Final temperature = 422 K
Initial temperature = ?
Solution:
The given problem will be solve through the Charles Law.
Charles Law:
According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.
Mathematical expression:
V₁/T₁ = V₂/T₂
V₁ = Initial volume
T₁ = Initial temperature
V₂ = Final volume
T₂ = Final temperature
Now we will put the values in formula.
V₁/T₁ = V₂/T₂
T₁ = V₁T₂ / V₂
T₁ = 359 mL × 422 K / 269 mL
T₁ = 151498 mL.K / 269 mL
T₁ = 563.19 K
