Hope this helps
Explanation:
Thermal energy, which is more commonly known as heat, is a form of energy. It is measured in joules. Thermal energy is an internal energy for a given system. Thermal energy is the cause for the temperature of a system.
Temperature is the measureable thermal property of a system. It is measured in Kelvin, Celsius, or Fahrenheit. The SI unit for temperature measurement is Kelvin.
Differences:
Thermal energy is not a directly measurable quantity whereas temperature is a measurable quantity.
• The temperature of an object can take negative values depending on the unit system used to measure the temperature, but the thermal energy of a system cannot be negative.
• Temperature is measured in Kelvin whereas thermal energy is measured in Joule.
• An object can lose or gain thermal energy in a state transition without changing the temperature of the system.
Answer:
1. Molecular solids are usually excellent conductors of electric current.
Explanation:
Molecular solids are actually insulators (prevent electricity).
If the earth’s interior cools down then the convection currents will not be produced in the mantle and geologically leads to dead earth.
<u>Explanation:
</u>
Convection currents is the process by which the heated fluids will be made to float on the surface while the cooler fluids will get precipitated in the mantle. The high amount of heat in the earth's crust leads to transfer of them as magma on the surface of the mantle and then it will lose its energy and precipitate as tectonic plates.
So, convection currents leads to the movement and production of new tectonic plates. If the earth's interior gets cooled down, then the creation of convection currents will cease leading to a geologically dead earth.
Answer:
concentration of ![[O_2]](https://tex.z-dn.net/?f=%5BO_2%5D)
= 0.0124 = 12.4 ×10⁻³ M
concentration of ![[CO]](https://tex.z-dn.net/?f=%5BCO%5D)
= 0.0248 = 2.48 ×10⁻² M
concentration of ![[CO_2]](https://tex.z-dn.net/?f=%5BCO_2%5D)
= 0.4442 M
Explanation:
Equation for the reaction:
⇄ 
+ 
Concentration of 
= 
= 0.469
For our ICE Table; we have:
⇄ +
Initial 0.469 0 0
Change - 2x +2x +x
Equilibrium (0.469-2x) 2x x
K = ![\frac{[CO]^2[O]}{[CO_2]^2}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BCO%5D%5E2%5BO%5D%7D%7B%5BCO_2%5D%5E2%7D)
K = ![\frac{[2x]^2[x]}{[0.469-2x]^2}](https://tex.z-dn.net/?f=%5Cfrac%7B%5B2x%5D%5E2%5Bx%5D%7D%7B%5B0.469-2x%5D%5E2%7D)
Since the value pf K is very small, only little small of reactant goes into product; so (0.469-2x)² = (0.469)²
![x=\sqrt[3]{1.9929*10^{-6}}](https://tex.z-dn.net/?f=x%3D%5Csqrt%5B3%5D%7B1.9929%2A10%5E%7B-6%7D%7D)
x = 0.0124
∴ at equilibrium; concentration of = 0.0124 = 12.4 ×10⁻³ M
concentration of = 2x = 2 ( 0.0124)
= 0.0248
= 2.48 ×10⁻² M
concentration of = 0.469-2x
= 0.469-2(0.0124)
= 0.469 - 0.0248
= 0.4442 M
