What two examples is the physical change and chemical change of milk?
Physical change - make it frozen ; Chemical change - make it spoiled
Name two chemical processes for which inhibitors would be desirable?
A reaction inhibitor refers to a substance that decreases the rate of, or prevents, a chemical reaction. Two chemical processes for which inhibitors would be desirable are in food preservation and cleaning metal oxides.

What is co-polarization?
Analysis of circular polarization (CP) utilizes two independent, orthogonal, components: right- and left-hand circular (RHC and LHC). The desirable component, having the intended sence of rotation (right, or left), is called the copolarization component. The undesirable component, with the opposite polarization, is called the crosspolarization component. The mix of copolarization and crosspolarization components determine the quality of CP and correlates with the axial ratio.
What two properties of ag and au are desirable for use in making jewerly?
Shiny, metallic lustre.Easy to shape.
When is friction desirable and undesirable in rugby?
Desirable in scrummaging when the two packs form together. Without friction they would slip off which is dangerous. Friction is also desirable when making the tackle. And when sidestepping you need good grip. Undesireable when trying to evade the tackle.

What are 2 examples of a chemical change?
Light emitted, reaction gets hot/cold, precipitate formed, a gas is evolved, or a pH change
Why do take derivative?
To find rate of change. Two common examples are: rate of change in position = velocity and rate of change of velocity = acceleration.
What means having to choose between two undesirable choices?
dilemma
How does entropy and the enzyme's work?
The answer lies with proteins. A specific kind of protein called an enzyme lowers the activation energy of chemical reactions. Reactions that would normally take years happen in seconds. Figure 7.1 shows how this effect alters chemical equilibrium. Consider a set of chemicals that have two paths to interact as shown in figure 7.1. One reaction is a side reaction that is undesirable. The other is desirable. The enzyme lowers the activation energy for the desirable reaction making it happen quickly. The undesirable reaction does not have a chance. Also notice that the entropy of the universe is maximized by the undesirable reaction. Thus, from thermodynamic considerations, one might think that the undesirable reaction is always dominant, but because the laws of thermodynamics have no way to deal with time, this observation is seldom true. The enzyme is not violating the second law by forcing the reaction in the preferred direction. Its reaction is also spontaneous in that it also increases the entropy of the universe. By making the desired reaction happen faster, the enzyme does not give the undesirable reaction time to happen.
