A geologist discovers a fault in a massive rock while out in the field. He notices that the fault occurs at an angle and that th
Ludmilka [50]

Answer: normal fault

A fault refers to a planar or curved fracture in the rocks of the Earth crust, in which compressional or tensional forces results in the displacement of the rock on the opposite side of the fracture. Fault may vary in the length of the fracture. A normal fault is a fault in which the hanging wall of the rock moves downward to the footwall. It occurs when the two blocks of rock are separated apart by the tensional forces.  

On the basis of the above information, the normal fault is the fault that should be found by the geologists in the rock.

13. What is the symbol for Enthalpy change?
OverLord2011 [107]

Answer:

Explanation:

13 ) symbol of enthalpy change = Δ H .

14 ) enthalpy change is nothing but heat absorbed or evolved .

During fusion enthalpy change

Δ H .= m Lf , m is mass and Ls is latent heat of fusion

During evaporation, enthalpy change

Δ H .= m Lv , m is mass and Lv is latent heat of evaporation

during temperature rise , enthalpy  change

Δ H = m c Δ T

In case of gas , enthalpy change can be calculated by the following relation

Δ H = Δ E + W , Δ E is change in internal energy , W is work done by gas.

15 ) When enthalpy change is negative , that means heat is released to the environment .So reaction is called exothermic .

when heat is absorbed enthalpy change is positive . Reaction is endothermic.
