This quiz covers Chapter 2 in the Integrated Science textbook: Cells

Specific Heat Capacity

First some confusing vocabulary – this is Chemistry after all…..

Specific Heat Capacity ‘C’ relates the amount of heat (energy or work) needed to raise a sample of some material 1 degree C.
Think of Specific Heat Capacity as the sample’s capacity to absorb heat, so the formula should include the amount of material in the sample, ie its mass.

Q = m  C  ΔT

Q: heat absorbed by the sample
m: mass of the sample
C: heat capacity of the sample material
Δ: change or difference of…
T: temperature
The units of C is
 ‘
 
Specific heat or specific heat capacity ‘s’ is the heat capacity, which is independent of the amount of substances. It can be defined as the quantity of heat required to raise the temperature of one gram of a substance by one degree Celsius (or one Kelvin) at a constant pressure. The specific heat of water is 4.18 joules/(gram degree C).

Q =
 

Refraction

In this post, I included the lecture notes for a development of Snell’s Law (1621) using a Huygen’s Wavelet construction (c. 1670). Special case: Total Internal Reflection leads to a 10 minute mini lecture on optical fibres, T1 cables, repeaters and IR wavelength demultiplexing. Continue reading Refraction

Newton’s Laws

What you need to know:
Newton proposed 3 “Laws”
1] Inertia: An object at rest tends to remain at rest unless acted on by an eternal force. An object in motion tends to remain in motion unless acted on by an external force.
2] Force and Mass: Remember the equation F = ma where F is the force {in units of Newtons – what else could it be?}, a is acceleration and m is an experimentally determined constant of proportionality for an object. m is called the mass.
3] Law of reaction: For every action there is an equal and opposite reaction.

Easy to remember examples:
1] A body in motion, stays in motion…
2] Here’s a joke: A Physicist walks into a bar, and he says…….. “F = ma”
that’s it, pretty funny eh?
3] Push someone and they’ll push back.

y=\frac{x^2}{2\pi \sqrt{10^{\frac{1}{2}}}}y=\frac{x^2}{2\pi \sqrt{10^{\frac{1}{2}}}}

 

y=\frac{x^2}{2\pi \sqrt{10^{\frac{1}{2}}}}

 

y=\frac{x^2}{2\pi \sqrt{10^{\frac{1}{2}}}}

 

y=\frac{x^2}{2\pi \sqrt{10^{\frac{1}{2}}}}

Physics Secrets eBook

Physics Secrets

The book has been developed for students of 15 years of age and above. Physics Secrets is ideal for helping both English speaking students and ESL students. It has been written for students studying physics at School or students studying science at University. I believe it will greatly assist you with the course you are doing.

There is a large amount of material out there that has merit but I believe that Physics Secrets will make it easier for you to understand and recall the subject quickly, as the book gives you an immediate understanding of the fundamentals.

Physics has a language and once you have an understanding of the language you will achieve much better results. The book’s unique approach explains the language and gives you mental images that are easy to remember.
