Answer:
Temperature at which molybdenum becomes superconducting is-272.25°C
Explanation:
Conductor are those hard substances which allows path of electric current through them. And super conductors are those hard substances which have resistance against the flow of electric current through them.
As given, molybdenum becomes superconducting at temperatures below 0.90 K.
Temperature in Kelvins can be converted in °C by relation:
T(°C)=273.15-T(K)
Molybdenum becomes superconducting in degrees Celsius.
T(°C)=273.15-0.90= -272.25 °C
Temperature at which molybdenum becomes superconducting is -272.25 °C
Answer:
The answer to your question is below
Explanation:
There are 4 laws of gases
- Charles
- Gay Lussac
- Boyle - Mariotte
P1V1 = P2V2
- General law of gases
Let's use these formulas to answer the question
p2 = V2/P1 This is not a law of gases
p1= V1/k This formula is similar to Boyle mariotte equation
but is not.
V2 = k/P2 This equation is correct is Boyle Mariotte formula
V2 = P1V1/ P2 This equation is also correct is Boyle Mariotte formula
V1 = P1/P2 (V2) This equation is incorrect
P2 = (P1) V1/V2 This equation is correct is Boyle mariotte formula
Answer:
The characteristic best supports its formation from sedimentary processes is "It has many layers."
Explanation:
When sediments deposit and solidifies then it results in the formation of sedimentary rocks.The given picture shows that this rock has many horizontal lines of different width and color. This shows that this rock is formed by many different layers. Thus, we can conclude that the characteristic which best supports its formation from sedimentary processes is that it has many layers. The layers present gives us an idea about the past events that has occurred for the formation of the or the deposition of the sedimentary rock.
Answer:
A) The reverse of the reaction is spontaneous
Explanation:
Spontaneous means those reaction which occur own their own or just need an initiation. As we know that,
∆G = ∆H-T∆S,
A reaction is spontaneous if ∆G Comes out to be negative . Because only those reactions occur in which either ∆H ( enthalpy change) is negative or ∆S (entropy change) is positive or both condition satisfied , as if in a reaction, let
A + B ------> B + C
If ∆G is positive when reaction proceed in forward direction, i.e. , it means it will be negative if proceed in backwards direction i.e on reactants side . Which means for such reaction backwards reaction is spontaneous.
