The triple point of Carbon Dioxide is 216.58 K (-56.57 °C), 518.5 kPa (5.117197 atm) so pushing the pressure higher and the temperature lower shifts it solidly into the solid phase.
Another way of checking it is to note that the vapor pressure of solid Carbon Dioxide at -60 °C is 4.043 atm so increasing the pressure to 15 atm would certainly push it further into the solid phase.
25 deg. Celsius is about "room temperature," and assuming normal pressure (1atm) carbon dioxide is a gas.

The same as most substances, CO2 must be cooled and put under increased pressure to become a solid. At one atmosphere, CO2 must be cooled to a temperature of -78.5 degrees Celsius to solidify. At height pressures CO2 solidifies at higher temperatures, however solid CO2 never exists at a temperature above -56.4 degrees Celsius.
The solubility of sulfur dioxide in water is 94 g/L.
Sulfur dioxide has a boiling point of −10°C (14°F) while silicon dioxide has a boiling point of 2230°C (4046°F). With these numbers in mind the difference would be 2240 °C (4064°F).

CO2, or carbon dioxide, will freeze at -78 degrees Celsius at normal pressure.

At standard pressure, CO2 does not occur as a liquid, the solid phase turns directly into a gas. Liquid carbon dioxide only forms at pressures higher than 5.1 atm. The actual boiling point depends on the pressure. At a particular pressure the liquid may have any temperature between the melting and boiling points. At the lowest pressure where it can exist, liquid carbon dioxide would have a temperature of -56.6 degrees C, or -69.88 degrees F. Under normal pressure conditions, carbon dioxide goes from gas straight to solid when the temperature reaches - 78.5 degrees C.
Henry's law constant for Carbon Dioxide at 20 degrees Celsius is: 1,6*10^3 ATM

The freezing point of co2 is -78.5When studying chemistry, it is important to know the freezing point of things that may be handled. The Freezing point of Carbon Dioxide is -108.4 degrees Fahrenheit.

Dry ice is simply the chemical carbon dioxide in its solid state. Dry ice is very cold and sublimates directly into carbon dioxide gas at negative 78.5 degrees Celsius at sea level.
