Answer:
Option B - Density increases
Explanation:
Density is defined as:
δ = mass / volume
When T°2 is > T°1, volume has been increased
As the volume increased, density has decreased.
↓δ = mass / volume ↑
In the situation above, temperature decreased from 4° to 0°.
The volume has been reduced, so the density has been increased.
↑ δ = mass / volume ↓
Answer:
D
Explanation:
Al is a reducing agent because it removes Oxygen from another compound
Mno2 is an oxidizing agent
Using the equation gpe = mgh
(Gravitation Potential Energy = mass x acceleration due to gravity which is 10 on earth x height)
Gpe = 8kg x 10 x 10m = 800
Definitely, the answer is false. A desiccant is a substance used in order to absorb moisture in the surroundings. It is a hygroscopic material that removes humidity since humidity will aid in the degradation or destruction of materials which are sensitive to moisture.
