Heat Transfer Lab
The following represents a lab set up for heat transfer. The cup on the left started with boiling water at 100 degrees C and the cup on the right has water at 20 degrees C. There is an aluminum bar between the two cups allowing heat to transfer from one cup into the other. The set up will be left alone for 20 minutes and temperatures of each cup of water will be recorded every minute for 20 minutes.

Gravitational potential energy will rises
Answer:
The analogy that best describes is "The planets go around the sun."
Explanation:
The best analogy that suggests that electrons moves round the nucleus in an atom is the Bohr model. According to Neil Bohr, Based on Rutherford's model, he suggested that the extra nuclear part consists of electrons.
These electrons are in the spherical orbits called shells or energy levels around the nucleus.
The nucleus is the tiny massive center of the atom.
Transition of electrons takes place from one level to another.
Answer:Rate of reaction can be determined in terms of concentration of reactants consumed or concentration of product formed per unit time
Explanation: For the reaction below
A ===>B
The reactant is A while the product given is B.
Reaction rate = Δ[B]/Δt = -Δ[A]/Δt
The concentration of A will decrease with time while the concentration of B will increases with time.
The negative sign in -Δ[A]/Δt is to convert the expression to positive since the change will always be negative (decreases)
