What rule can you state about the relationship between phase chages and temperature?
Phase changes absorb or release heat energy.
Condensation (from gas to liquid or gas to solid) releases the most heat. The gas molecule, flying around at the speed of sound, had more energy than when it is condensed in a liquid. That difference in energy is released as heat. That's why a steam burn can be so bad - it is a lot of heat.
Evaporation (liquid to gas) and sublimination (solid to gas like dry ice reating a CO2 fog) absorb heat. That's why sweating cools you. The water absorbs a lot of heat as it evaporates. The energy amounts are equal and opposite of condensation.
Melting (solid to liquid) absorbs heat and freezing releases heat. So your freezer must pump heat out of the ice tray to make ice cubes. Those ice cubes, when in a drink, cool the drink by absorbing heat as they melt.

What is a graph of the relationship between the physical state of a substance nad the temperature and pressure of a substance?
A phase diagram illustrates the relationship between the physical state (solid, liquid, gas) of a substance and its temperature and pressure. Different regions on the diagram correspond to different states of matter based on the prevailing conditions of temperature and pressure. The boundaries between the regions represent conditions where phase transitions occur.
What do phase diagrams describe for a particular substance?
Phase diagrams describe the relationship between temperature, pressure, and the phase of a substance (solid, liquid, gas). They show the conditions under which a substance exists in different phases or transitions between phases.
What is diagram phase answer?
The simplest phase diagrams are pressure-temperature diagrams of a single simple substance, such as water. The axes correspond to the pressure and temperature. The phase diagram shows, in pressure-temperature space, the lines of equilibrium or phase boundaries between the three phases of solid, liquid, and gas.
How is a heating curve used to relate to phase changes and temperature and kinetic energy?
A heating curve shows the relationship between temperature and heat added to a substance. During phase changes, the temperature remains constant as the added heat is used to break intermolecular forces. Kinetic energy increases with temperature, so during phase changes, the added heat is used to increase potential energy (for breaking intermolecular forces) rather than increasing kinetic energy (temperature).
What is saturated phase?
The saturated phase is a phase in which a substance exists at a temperature and pressure where it is in equilibrium between its liquid and vapor states. In this phase, the substance's properties such as temperature, pressure, and composition remain constant until all the substance has completely vaporized or condensed.
Why phase diagram is called equilibrium diagram?
A phase diagram of the equilibrium relationship between temperature, pressure, and composition in any system.
What is the graph of a relationship between the physical state of a substance and the temperature and pressure of the substance?
Phase diagram?
What is te rule that describes the relationship between phase changes and temperature?
Increasing the temperature a solid material become a liquid and further a gas.
What is the relationship between temperature and vapor pressure?
The relationship between temperature and vapor pressure is direct and proportional. As temperature increases, the vapor pressure of a substance also increases. This is because higher temperatures cause more molecules to have enough energy to escape from the liquid phase and enter the gas phase, increasing the pressure of the vapor above the liquid.

What rule can you state about the relationship between phase changes and temperature?
As the temperature increases, the phases change from having the slowest amount of molecules to having the fastest amount of molecules (solid-liquid-gas)
What is the relationship of temperature to heat?
The specific heat is the quantity of heat needed per unit mass to increase the temperature by one degree Celsius. The relationship between variations in heat and temperature is generally expressed in the form below, where the real heat is c. When a phase shift is observed, the relationship does not apply, so the heat applied or extracted during a phase change does not change the temperature.
What is the relationship between temperature and sublimation pressure in a solid substance?
The relationship between temperature and sublimation pressure in a solid substance is that as temperature increases, the sublimation pressure also increases. This means that at higher temperatures, the solid substance is more likely to change directly into a gas without passing through the liquid phase.
Why is it the phase relationship between input and output signals of the common collector amplifier is in phase?
no phase shift
Is the relationship between the temperature of water and the solubility of a gas in it a direct or inverse relationship Explain?
The temperature of water and the solubility of a gas are in an inverse relationship; gases are more soluble at low temperatures.
What information does a phase diagram give?
The effect of temperature and pressure on the phase of a substance
