What is significant about the temperature absolute zero?

Reptile [31]

Explanation:

The absolute temperature is the lowest possible temperature in the universe. At this temperature, all atoms become motionless and cease to move.

The value of the absolute zero is pegged at -273.16°C.

It is the lowest limit of the coldness of a body.
Nothing can be colder than a body at absolute temperature.
Many researches are underway to take advantage of this temperature value for scientific purpose.
Thermodynamically, all process stops at this temperature.
When a body is brought close a body at absolute zero, it can suffer cryogenic burn due to heat transfer.

The glancing angle (θ) of a Bragg reflection (n = 1) from a set of crystal planes separated by 99.3 pm is 10.42°. Calculate the

Rufina [12.5K]

Answer:

wavelength λ = 35.92 pm

Explanation:

Given that:

The glancing angle (θ) = 10.42°

Bragg reflection n = 1

wavelength λ = ???

diameter d = 99.3 pm

Using the formula:

nλ = 2dsinθ

we have:

1 × λ = 2 × ( 99.3) × sin (10.42°)

λ = 198.6 × 0.18086

λ = 35.92 pm

A certain radioactive isotope has a half-life of 5 days. If one is to make a table showing the half-life decay of a sample of th

Pepsi [2]

It will take 25 days for this substance to become 1gram from 32 grams.

<h3><u>Explanation</u>:</h3>

Radioactivity or radioactive decay is the process of formation of different element from one Radioactive element due to decay of the radioactive nucleus. The radioactive decay is a first order kinetic reaction. This reaction has a straight log C vs T graph.

Here in this particular reaction, the half life of the radioactive substance is 5 days. So within 5 days, the concentration of the substance becomes halved.

Now, in the sample the amount of substance present = 32 grams

The final amount of this sample = 1 grams.

So number of half lives needed for this decay = 5 half lives.

So number of days required for this decay = $5\times5$ =25.

So within 25 days, 32 grams of the substance becomes 1grams.
