Answer:
1. An oxidising agent is the one which oxidises other substances (by removal of hydrogen or addition of oxygen) and itself gets reduced (addition of hydrogen or removal of oxygen).
2Mg+O
2
→2MgO
In the above reaction, oxygen acts as an oxidising agent as it oxidises magnesium (Mg) to form magnesium oxide (MgO).

2.The specific latent heat (L) of a material… is a measure of the heat energy (Q) per mass (m) released or absorbed during a phase change. is defined through the formula Q = mL. is often just called the "latent heat" of the material. uses the SI unit joule per kilogram [J/kg].
3.Q=mcΔT Q = mc Δ T , where Q is the symbol for heat transfer, m is the mass of the substance, and ΔT is the change in temperature. The symbol c stands for specific heat and depends on the material and phase. The specific heat is the amount of heat necessary to change the temperature of 1.00 kg of mass by 1.00ºC.
