The density of ice does not affect its melting rate. Adding objects will affect the melting rate.
- A physical process called melting or fusing causes a substance to change its phase from a solid to a liquid. This happens when the solid's internal energy rises, usually as a result of heat or pressure being applied, which raises the substance's temperature to the melting point.
- The term "density" refers to an extensive quality, which means that it is independent of the substance's concentration. Every substance in the world demonstrates its distinctive density. Since it does not fluctuate, it would not affect the rate of melting. The addition of the objects could speed up the process, though, as each one generates heat that could act as the mediating force for the melting process.

Answer:
Sodium sulfate(Na2SO4) is a salt
Explanation:
It is a neutralization reaction in which sulphuric acid (H2SO4) which is composed of sulfur, oxygen, and hydrogen. Sulphuric acid is strong acid reacts with 2 moles of Sodium hydroxide (in neutralization reaction 1 mole of sulphuric acid is equal to 2 moles of Sodium hydroxide) gives us 2 moles of water and sodium sulfate (Na2SO4) which is composed of sodium, sulfur, and oxygen.
Sodium sulfate (Na2SO4) is salt, when H2SO4 reacts with sodium hydroxide (due to hydrate) it will give us salt (Na2SO4)
Answer:
Average net force = 0.62 N
Explanation:
We are given;
Mass; m = 1.7 kg
Initial velocity; u = 12.5 m/s
Final velocity; v = 25 m/s
time; t = 25 seconds
Now, we are told that the final velocity was 30° west of North. So, resolving this velocity along the horizontal gives;
v = 25 cos 30°
Now, using Newton's first equation of motion gives;
v = u + at
Where a is acceleration
Plugging in the relevant values gives;
25 cos 30° = 12.5 + 25a
21.6506 - 12.5 = 25a
a = (21.6506 - 12.5)/25
a = 0.3660 m/s²
Now, magnitude of the average net force would be; F = ma
F = 1.7 × 0.366
F ≈ 0.62 N
