Room temperature is above the critical point for temperature of Oxygen, which means a liquid can not be formed. Even under great pressure at this temperature, it will not form a liquid, but instead a gas with some liquid characteristics.
Calculate The Amount Of Heat Needed To Melt 29.7g Of Ice (H2O) And Bring It To A Temperature Of 90.7 Degrees Celsius?
1 cal = 1 gram H2O raised 1 degree Celsius. Ice is 0 degree C. 4.184 J = 1 cal
