Screen Reader Description: The Ordinary Phases of Water. Image: Graph of Temp (Kelvins from 0 to 700) on X axis, P (atm) on Y axis (from 10 to the power of 0 to 10 to the power of 8, pressure, (P a)). There is a curve starting at 200 on the X axis and 10 to the power of 0 on the Y axis. The line goes upward to the right to finish at 610 on the X axis and 10 to the power of 7 on the Y axis.  There is a straight line with a slightly negative slope starting at 260 on the X axis and 10 to the power of 8 on the Y axis that goes downward until it hits the curve and stops. To the left of the straight line is the word "Solid". Between the straight line on the right and the curve is the word "Liquid". To the right side of the curve is the word "Gas".  End of image.   The critical temperature is:   0 K   100 K   200 K   300 K   400 K   500 K   600 K   700 K   100 Pa   101 Pa…

please help me with my hw. Please answer letter b completely. Hoping for you to help me as i am struggling so much. Tysm❤️ TYPES OF SOLIDS AND THEIR PROPERTIES Solids can be categorized as crystalline and amorphous. The difference in properties of these two groups of solid arises from the presence or absence of long range order of arrangement of the particles in the solid.   Properties Crystalline Solid Amorphous solid Arrangement of particles Arranged in fixed geometric pattern or lattices. Have random orientation of particles Behavior when heated Attractive forces are broken by same amount of energy, thus, becomes liquid at a specific temperature. Softens when gradually heated, they tend to melt over a wide range of temperature.   FACTS: More than 90% of naturally occurring and artificially prepared solids are crystalline. The repetition of structural units of substance over long atomic distances is referred to as long-range order. The repeating units…
