Manipulated variable: the types of soil
Responding variable: how much t the plants grow
According to zeroth law of thermodynamics, when two objects are kept in contact, heat (energy) is transferred from one to the other until they reach the same temperature (are in thermal equilibrium). When the objects are at the same temperature there is no heat transfer.
So, at equilibrium, 
=

+ 
q=m×c×T, where q = heat energy, m = mass of a substance, c = specific heat (units J/kg∙K), T is temperature
=(15X13X4.19)+(148X88.3X4.19)
= 81.37 ° C
Al2O3 has a higher melting point than Na2O. This is because the ionic bond between Al3+ ions and O2- ions is stronger than that between Na+ and O2-. The charge on the Al3+ ion is larger than that of the Na+ ion
The animal kingdom includes <span>multicellular organisms. Also the cells of the species in this kingdom have a nucleus but no chloroplasts or cell wall. </span>
It is the largest of all of the six kingdoms and includes mammals, birds, reptiles, insects and more.
