Answer: physical, chemical
Explanation:
Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass.It can be decomposed into simpler constituents using chemical reactions. Example:
Mixture is a substance which has two or more components which do not combine chemically and do not have any fixed ratio in which they are present. Example: Air
The components of mixture do not react chemically and thus the constituents retain their chemical properties. Thus mixtures can be separtated by a physical change.
The components of compound lose their individual chemical properties. The components have to be separated by a chemical change.
Answer:
Explanation:
The maximum theoretical efficiency for a heat engine is given by the Carnot's Cycle. The temperatures of the hot reservoir and the cold reservoir at 1.0 atmosphere are 373.15 K and 273.15 K, respectively. Then:
Answer:
The heterogeneous mixture that has very small dispersed particles and stays mixed for a long time is colloid. Because colloid has particles that are small enough to suspended but are as large that they can scatter light.
Answer:
The correct options are;
C. Divergent plate boundary
D. Normal faults
Explanation:
Tensile stress tends to pull objects part by acting axially upon the object to pull the object on a cross section perpendicular to the objects cross-section
The most common stress in convergent plate boundaries is compression stress
The most common stress in divergent plate boundaries is tensile stress
In the presence of tensile stress, normal faults results in the raising of mountains due to their enormous forces
Therefore, the features of Earth's crust involving tension are divergent plate boundary and normal faults.
