The video is displayed on a white paper with a graph on the left side. The graph is a line graph that shows the relationship between the two phases of water. The x-axis represents the temperature and the y-axis indicates the pressure and pressure of the water.

On the right side of the image, there is a person's hand holding a green pen and pointing to the graph. The person is wearing a black shirt and appears to be in the middle of a presentation. The background is a wooden table.</caption><caption><image_31>The image is a screenshot of a video titled "Compare the phase diagram for water to that for CO2". It shows a graph on a white paper with a person's hand holding a green pen. The graph is a line graph that shows the relationship between the two phases of water. The x-axis of the graph represents the temperature and the y-axis represents the volume of the water.

There are two lines on the graph, one labeled "liquid" and the other labeled "solids". The graph shows that the liquid is higher than the solids and the temperature is lower than the gas. The solids are represented by a red line, while the gas is shown by a blue line. The temperature is shown as a light blue color and the gas has a darker blue color. There is also a small image of a person in the top right corner of the image, who appears to be a scientist or a scientist.</caption></video><transcript><audio_32>same kind of line here same liquid gas line although we don't extend it quite as far to get to the triple point slope</transcript><caption><image_33>The image shows a person's hand pointing to a graph on a white paper. The graph is a line graph that shows the phase diagram for water to that for CO2. The x-axis represents the time period, while the y-axis is labeled with the temperature and pressure of the water. The line graph shows that the temperature is higher than the pressure, with the highest temperature at the top and the lowest at the bottom.

On the top right corner of the image, there is a video clip of a man in a suit and tie, who appears to be explaining the graph. The video clip is titled "Compare the phase diagrams for water" and has a caption that reads "Slope is positive".</caption><transcript><audio_34>which means the solid is more dense than</transcript><transcript><audio_35>the liquid which is how it happens for 99.9999% of materials not water all right so we're comparing to the phase diagram for co2 we can see that one</transcript><transcript><audio_36>atmosphere is down here so if we were to do the heating curve for co2 it would go straight from the solid the gas phase that will only cross the solid to gas</transcript><caption><image_37>The image is a screenshot of a video titled "Compare the phase diagram for water to that CO2". It shows a person's hand holding a black pen and writing on a white paper. The paper is divided into two sections.

On the left side of the paper, there is a graph that shows the relationship between the two phases of water. The first phase is labeled "Solid" and the second phase is labelled "Slope". The graph shows that the water has a positive slope and a negative slope. The graph also shows that there are two points on the x-axis of the graph, one labeled "Liquid" and one labeled with a liquid. The text on the paper explains that the person is comparing the phase to the water for the CO2 solution.</caption><transcript><audio_38>however if we wanted to do co2 as higher pressures we could get it to go from solid to liquid to gas the other thing</transcript><transcript><audio_39>is supercritical carbon dioxide is a material that gets used and quite often as an extracting agent it can it's actually not that hard to make 73 atmospheres and this temperature is just</transcript> slightly farther apart to maximize their hydrogen bonding moving farther apart means less dense h2o molecules so the slope of this line being negative is related to why ice floats and ice floats because hydrogen bonding is maximized by moving the water molecules slightly farther apart when it freezes into the solid phase so that's what's interesting about but almost every other substance this line is positive I'll show you an example of that right now so here's water's phase diagram here's the phase diagram for carbon dioxide same kind of line here same liquid gas line although we don't extend it quite as far to get to the triple point slope which means the solid is more dense than the liquid which is how it happens for 99.9999% of materials not water all right so we're comparing to the phase diagram for co2 we can see that one atmosphere is down here so if we were to do the heating curve for co2 it would go straight from the solid the gas phase that will only cross the solid to gas however if we wanted to do co2 as higher pressures we could get it to go from solid to liquid to gas the other thing is supercritical carbon dioxide is a material that gets used and quite often as an extracting agent it can it's actually not that hard to make 73 atmospheres and this temperature is just
