If i had a quantity of this substance at a pressure of 0.75 atm and a temperature of -1000 c, what phase change(s) would occur if i increased the temperature to 6000 c? at what temperature(s) would they occur?

1/0.14nm = 10^10/1.4 a lot

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.

i really dont know but i will try okay.

so i think u would just add all them up and get your answer..

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.
