25 deg. Celsius is about "room temperature," and assuming normal pressure (1atm) carbon dioxide is a gas.
If the melting point is at -77.74 degree celsius and boiling point of -33.33 degree celsius.
Frozen carbon dioxide is still carbon dioxide, so it is a physical change.
It is 31 Celsius.
See the Related Question (link to the left of this answer)."How many moles of carbon dioxide are there in a 50.0 dm3 sample of the gas at a pressure of 100.0 kPa and a temperature of 50 degrees celsius?" 1.86 moles
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.
-57 degrees C. Or -70 degrees F
Henry's law constant for Carbon Dioxide at 20 degrees Celsius is: 1,6*10^3 ATM

25 deg. Celsius is about "room temperature," and assuming normal pressure (1atm) carbon dioxide is a gas.
Frozen Carbon Dioxide
CO2, or carbon dioxide, will freeze at -78 degrees Celsius at normal pressure.
Both are in gaseous state at 25Celsius
At higher temperatue it decomposes and the carbon content can get converted to carbon dioxide.
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.
Carbon dioxide is a gas at 20 Celsius. It deposits into a solid at -80 Celsius.
Frozen carbon dioxide is still carbon dioxide, so it is a physical change.
At 100 degrees C, malic acid is still a solid. At 130 degrees C, malic acid will decompose and form carbon monoxide and carbon dioxide gases.
The normal body temperature of a healthy human being is 98.6 degrees Fahrenheit or 37.0 degrees celsius.
