The correct answer is 2.
In oxidation-reduction reactions (or redox reactions), a number of electrons are transferred between two species. During this process, the oxidation number of an atom (or molecule or ion) changes by receiving or losing an electron.

Answer:
Now "q" is the heat and energy is the capacity of any object or body ton perform any work. So we can relate them if we take the term specific heat in consideration.
As specific heat is the the amount of heat required to raise the temperature of an object in specific from one degree Celsius, for ice it is 2.108 kJ/kgK.
Explanation:
- c = specific heat capacity,
- ΔT = change in temperature
So, we have:
- It is the ratio of the amount of heat energy transferred to an object to the resulting increase in temperature of the object.
The formula of work is Work (Joules)=Force (Newtons) · distance in the direction of the force (meters), therefore its just a matter of replacing factors.
Work done = 12 · 4.5= 54 joules
The angle of incoming solar radiation influences seasonal temperatures of locations at different latitudes. ... At higher latitudes, the angle of solar radiation is smaller, causing energy to be spread over a larger area of the surface and cooler temperatures.
