Chemistry

4 0
The phase of a substance at a temperature of 275 K or 1.85 degrees Celsius can be any of the three phases namely a solid, a liquid and a gas. This depends on the pressure where the substance is subjected. Also, the phase can be determined by a phase diagram where it shows the phase of a certain substance at a specific temperature and pressure.

Strike441 [17]

Answer:

<h2>2.70 g/cm³</h2>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume} \\

From the question we have

density =  \frac{21.6}{8}  \\  = 2.7

We have the final answer as

<h3>2.70 g/cm³</h3>

Hope this helps you

What to do when your friend hates you for something you did not do?
fgiga [73]

Answer:

This is a tricky one because this person was a massive part of your life, and now they're not. You're probably feeling hurt, confused, lonely and angry all at once. I have been here too and it's horrible so my thoughts are with you! For me, I had to make peace with it. It sounds silly but unfortunately there's not much we can do to try and win them back. If someone can go from being your best friend to all of a sudden hating you then they probably don't care about you as much as they should, and you're probably better off without them :) Seek people who actually care for you, and want to spend time with you. Friendships come and go, and as much as it hurts, if you can accept this and cherish your real friendships (the ones where you can go years without seeing eachother, but are there like a shot when you need them) then the pain should diminish. Good luck :)

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.
