<h2>Answer:</h2>
The phase of matter will be known as the forth phase of matter, plasma.
<h3>Explanation:</h3>
There are 4 phases of matters:
- Gas: The freely moving molecules, having no definite volume and shape.
- Liquid: The loosely bonded molecules, having a definite volume but not shape.
- Solid: Highly packed molecules with definite volume and shape.
- Plasma: The more like gases phase, containing freely moving electrons and positive ions.
Hence according to the question description and given above matter phases, the phase of that sample will be plasma.
because Magnesium oxide has a high melting point (2852°C) and so resists the high temperatures in a furnace.It is known as a refractory material - which just means that it is resistant to heat.
Question:
Which of the following statements is TRUE?
A. Perpetual motion machines are a possibility in the near future.
B. The entropy of a system always decreases for a spontaneous process.
C. A spontaneous reaction is always a fast reaction.
D. There is a "heat tax" for every energy transaction.
E. None of the above are true.
Answer:
The correct answer is D)
There is a "heat tax" for every energy transaction.
Explanation:
Heat and work are two different ways in which energy is moved from one device to another. In the field of thermodynamics the distinction between Heat and Work is significant. The transfer of thermal energy between systems is heat. This is what is referred to as "heat tax".
No other statement in the question above is correct.
Cheers!
Change in size because that just means that more is added rather than anything reacting
Answer:
Using the Guess Method
Explanation:
Finding the square root of a number is an automatic action in tools such as calculator and Excel without any rationale behind it. Hence, I find it more useful to describe as I learned at school: the guess and approach method (it can go by various other names).
The square root of a number is ‘a number which produces a specified quantity when multiplied by itself’.
The Guess Method is guessing that number by approximation until getting exactly the right one.
For example, we want to know the square root of, let’s say, 144. We know that 10*10 is 100. That’s close. Let’s add 1 to that. 11*11 is 121. Getting closer! 12*12 is… 144! Right on! Therefore, the square root of 144 is 12.
I used that technique every time I had to do the math by hand, no matter the number. I thought of a number that could be somewhat close enough (I would guess! Got the method name now? Lol) and adjust until I got my answer right.
