What is the critical temperature of dimethyl sulphoxide?
The critical temperature of dimethyl sulfoxide (DMSO) is 189°C. The critical temperature is the temperature at which a substance transitions from a gas to a liquid regardless of pressure.
What is Critical point of phenol-water system?
The critical point of the phenol-water system occurs when the temperature and pressure reach the critical values at which the distinction between liquid and gas phases disappears. At this point, the properties of both phases become indistinguishable, leading to a critical point that represents the maximum temperature and pressure at which the two phases can coexist.
What is difference between temperature and critical temperature?
Temperature refers to the measure of thermal energy present in a substance, while the critical temperature is the specific temperature at which a substance transitions from one phase to another (such as from liquid to gas). The critical temperature is a unique property of a substance and is independent of pressure.
What is pseudo critical pressure and temperature?
Pseudo critical pressure and temperature are values used to determine the compressibility factor of a gas. They are calculated based on the critical properties (critical temperature and critical pressure) of a gas and are used in the generalized compressibility chart to determine the compressibility factor. This factor helps in predicting the behavior of a gas under different conditions.
Why is water a critical element on earth?
Water is critical on Earth because it is essential for all forms of life to survive and thrive. It regulates temperature, transports nutrients, and provides a habitat for many organisms. Water is also crucial for various processes like photosynthesis and digestion.
What is the critical temparature?
The temperature at which all the physical states of matter are coexists is called critical temperature. The temperature above that the gas can not be liquefied is called critical temperature of that gas.Gases with high critical temperature are liquefied easily.
What happened when impurity is added in phenol water system?
the critical solution temperature for phenol water system increases

What Three of the most important cycles that affect the atmosphere?
The sun, temperature and precipitation.
What is the critical temperature of oxygen?
The critical temperature of oxygen is approximately -118.6 degrees Celsius. At this temperature, oxygen cannot exist in liquid form and will transition directly from gas to solid.
What is the effect of temperature on thermal conductivity of water?
106 k (cgsu)= -1390.53 + 15.1397 T - 0.0190398 T2 (T in K) from 277.16 to 413.16 As temperature increases, so does the thermal conductivity, reaching a maximum a bit before the critical point of water and then decreasing slightly as the critical point is approached.
Does temperature affect critical pressure?
Temperature does not directly affect critical pressure. Critical pressure is a characteristic property of a substance and remains constant regardless of temperature. At the critical point, the substance exists as a single phase, with distinct liquid and gas properties disappearing.
What is difference between temperature and critical temperature?
Temperature refers to the measure of thermal energy present in a substance, while the critical temperature is the specific temperature at which a substance transitions from one phase to another (such as from liquid to gas). The critical temperature is a unique property of a substance and is independent of pressure.
Why critical temperature is lower than melting temperature?
the critical temperature is for the phase stability? When the phase changes,the energy needed is smaller than the material melton,
What does the critical point represent?
Critical point is also known as a critical state, occurs under conditions at which no phase boundaries exist. There are multiple types of critical points, including vapor-liquid critical points and liqui-liquid critical points.
What are properties of critical temperature?
the highest temperature at which a substance can exist as a liquid , is called its critical temperature . e.g critical temperature of carbon dioxide is 31.142 degree centigrade .
