<em><u>In fission, energy is gained by splitting apart heavy atoms, for example, uranium, into smaller atoms such as iodine, caesium, strontium, xenon and barium, to name just a few. However, fusion is combining light atoms, for example, two hydrogen isotopes, deuterium and tritium to form </u></em>
<em>For example, uranium can fission to yield strontium and krypton. Fusion joins atomic nuclei together. The element formed has more neutrons or more protons than that of the starting material. For example, hydrogen and hydrogen can fuse to form helium.</em>
The step in which reactant escape from the surface into the gas phase is known as desorption
Desorption is a phenomenon whereby a substance is released from or through a surface. One substance is released from another either from the surface or through the surface. Desorption can occur when the system is in the state of sorption equilibrium between bulk (fluid) and adsorbing surface.( boundary separating two fluids)

Explanation:
Since the wheel moves up and down, the position that represents the potential energy is that which has the maximum height from the ground.
Potential energy is the energy at rest of a body.
It is given as:
Potential energy = m x g x h
m is the mass of the body
g is the acceleration due to gravity
h is the height of the body
We can see that mass and height are directly related to the potential energy a body exerts.
The higher the wheel from ground, the higher its potential energy.

In order to calculate the percentage of a substance (sucrose this time) in a sample of known mass, the mass of the substance needs to be determined first.
The mass of a substance can be determined from its number of moles and molar mass, such that:
mass = mole x molar mass
Once the mass of the substance is determined, the percentage of the substance in 20.0 g sample can be calculated as:
Percentage of substance = mass of substance/mass of sample x 100
Hence, assuming that the mass of sucrose is x g:
percentage of sucrose in the sample = x/20 X 100
= 5x %
