Concept explainers
(a)
Interpretation:
A diagram for the flow of water through pipes, which show the interrelation of voltage, current, and resistance has to be constructed.
Concept introduction:
SI-Base units: Weights and measurements adopted the “International System of units” which is a particular choice of metric units and this system has seven type SI base units is “length, mass, time, temperature, amount of substance,
For example, SI base unit of length and mass is, “meter (m)” and kilogram(kg) respectively.
Current: The number of electrons flowing per second and it is measured by the potential
Potential: The energy associated with each electron.
Resistance: It is the hindrance to the flow of electrons in respective materials.
(b)
Interpretation:
How accurate is this analogy and what are some limitations for the given description of electricity have to be explained.
Concept introduction:
SI-Base units: Weights and measurements adopted the “International System of units” which is a particular choice of metric units and this system has seven type SI base units is “length, mass, time, temperature, amount of substance, electric current and luminous intensity” and the SI units from all others can be derived. Meter, kilogram, second, kelvin, mole, ampere and candela are the SI base units.
For example, SI base unit of length and mass is, “meter(m)” and kilogram(kg) respectively.
Current: The number of electrons flowing per second and it is measured by the potential
Potential: The energy associated with each electron.
Resistance: It is the hindrance to the flow of electrons in respective materials.

Chemistry In Context
- Show the mechanism steps to obtain the lowerenergy intermediate: *see imagearrow_forwardSoap is made by the previous reaction *see image. The main difference between one soap and another soap isthe length (number of carbons) of the carboxylic acid. However, if a soap irritates your skin, they mostlikely used too much lye.Detergents have the same chemical structure as soaps except for the functional group. Detergentshave sulfate (R-SO4H) and phosphate (R-PO4H2) functional groups. Draw the above carboxylic acidcarbon chain but as the two variants of detergents. *see imagearrow_forwardWhat are the reactions or reagents used? *see imagearrow_forward
