What is the temperature at which a substance may exist in all three phases?
The triple point of a substance is the temperature and pressure at which all three phases are in equilibrium. The exact temperature and pressure depend upon the identity of the substance.
Which phases of a substance can exist when the pressure is less than the pressure of a triple point?
liquid & vapor
Which phases of a substance can exist whe the pressure is less than the pressure of the triple point?
All three phases.
What is room temperature and pressure?
NIL... Does NOT exist...As there is no medium inside the vacuum.
What conditions are called standard in thermodynamics?
Standard conditions are defined in terms of pressure, temperature, composition, and phase. The IUPAC standard temperature and pressure (STP) is: 0 °C and 1 bar. IUPAC standard AMBIENT temperature and pressure (SATP) is: 25 °C and 1 bar. "Standard State" is each substance in it's pure form in whatever state it would exist at STP. For example: Oxygen would be O2 gas at STP. Iron would be solid iron at STP. Water generally be liquid water at STP. In some cases you have to choose the most stable allotrope under those conditions: for carbon, we use graphite.
Which phase of a substance can exist when the pressure is less than the pressure of the triple point?
This depends on the temperature.
The triple point of a substance is the temperature and pressure conditions at which?
... the substance can exist in the solid, liquid, and gaseous phases all at the same time.
What is a substance's critical point?
the temperature and pressure where the liquid state no longer exist is called the critical point
What is the temperature at which a substance may exist in all three phases?
The triple point of a substance is the temperature and pressure at which all three phases are in equilibrium. The exact temperature and pressure depend upon the identity of the substance.
When can all three states of matter exist in equilbrium?
At the super critical point. The required temperature and pressure may vary depending on the substance
What does matter can change state mean?
The same substance can exist either as a solid, liquid or a gas and can change state depending on the temperature or external pressure.
What is the gaseous form of a substance which exist as a liquid at room temperature known as?
water is the substance
Which phases of a substance can exist when the pressure is less than the pressure of the triple point?
liquid & vapor
Which phases of a substance can exist when pressure is less than the pressure of the triple point?
liquid & vapor
Which phases of a substance can exist when the pressure is less than the pressure of a triple point?
liquid & vapor
What properties determine if something is a solid liquid or gas?
Fundamentally, the temperature and pressure, depending on the substance. Most substances may exist in any one of those three forms under certain conditions of temperature and pressure. For example, water may exist in all three forms simultaneously (ice, liquid, vapour) under very specific conditions of temperature and pressure which are referred to as the "triple point of water".
What are the differences between liquid and liquefied gas?
A liquid substance, like water or gasoline, normally is a liquid at ambient temperature and pressures.A liquified gas, like LPG or liquified natural gas, exists as a liquid as the result of compression andcooling to temperatures and pressures unlike the ambient temperatures and pressures.
