Answer:
It will reduce
Explanation:
The time it will take to bake the cake will reduce when the temperature is increased by an additional 20°F .
Temperature change has a considerable effect on reaction rates since temperature is directly proportional to the average kinetic energy of reacting particles.
Generally reaction rate varies as temperature directly.
Therefore, the baking time will reduce as temperature increases.
Explanation:
A mixture which shows presence of uniform composition of solute particles into the solvent is known as a homogeneous mixture.
- Distilled water is a clear solution in which there is uniform composition of solute particles into the solution.
- Gasoline is mixture of different compounds which are evenly distributed. Therefore, it is also a homogeneous mixture.
- Wine is also a clear solution in which particles are evenly distributed. Hence, it is a homogeneous mixture.
On the other hand, a mixture which shows non-uniform composition of solute particles into the solvent is known as a heterogeneous mixture.
- Beach sand is a mixture of different particles present in varying composition. Hence, it is a heterogeneous mixture.
- Also, in air there are different gases present in different composition. Mover over, there is presence of fog and smoke into the air. Hence, it is a heterogeneous mixture.
