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.

What the sample will look like after the temperature is increased from 300 K to 450 KK at constant pressure?
sleet_krkn [62]

Answer:

The sample will look expanded and occupy more space.

Explanation:

Since, the pressure is constant here, but the temperature is changed. Therefore, according to Charles' Law Volume is directly proportional to Temperature, provided the pressure is kept constant. Mathematically:

V1/T1 = V2/T2

V1 = (T1/T2)(V2)

V1 = (300 k/450 k)(V2)

<u>V1 = (0.67)V2</u>

The equation indicates that The fina volume of the gas V2 will be greater than the initial volume V1. <u>Thus, sample will look expanded and occupy more space than the previous state.</u>

A lab technician needs a 40% solution of a certain chemical for an experiment, but the lab that she works in only has a 20% solu
Snezhnost [94]

To determine the volume of both concentration of the solution to make another concentration of solution, we need to set up two equations since we have two unknowns. <span>

For the first equation, we do a mass balance:

mass of 50% solution + mass of 20% solution = mass of 40% solution
M1 + M2 = M3

For the second equation, we do a component balance,</span>

<span>
M1(50%) + M2(20%) = M3(40%)
.50M1 + .20M2 = .40M3

To determine the ratio, we assume we have to make a 100 g of the 40% solution. So, the equation would change to</span>

<span>
</span>

<span>M1 + M2 = 100</span>

.50M1 + .20M2 = (100)(.40) = 40


Solving for M1 and M2,

M1 = 66.67 g

M2 = 33.33 g


So, the ratio of the 20% and the 50% would be approximately 33.33/66.67 = 0.5.
