What can a boil be defined as?
Boiling, a type of phase transition, is the rapid vaporization of a liquid, which typically occurs when a liquid is heated to its boiling point, the temperature at which the vapor pressure of the liquid is equal to the pressure exerted on the liquid by the surrounding environmental pressure.
What will happen to bring a substance from a liquid to a gas?
To bring a substance from a liquid to a gas, it needs to undergo the process of vaporization or boiling. This occurs when the substance is heated to its boiling point, which is the temperature at which its vapor pressure becomes equal to the atmospheric pressure. As the substance absorbs heat, its particles gain energy and become more volatile, transitioning from the liquid phase to the gas phase.
What happens when ice is heated from 0 c to 10 c?
Ice is the solid form of water that generally has 4 hydrogen bonds, allowing the water to organize itself in a crystalline arrangement. This leads to ice being less dense than water (density is the amount of mass per volume). Heating it by 10 degrees Celsius will cause bonds to break, and it will become more liquid. To increase the temperature, however, you must first overcome the delta H (enthalpy) of fusion / vaporization. That is the amount of energy required to completely transition from phase to phase (heat of vaporization is the amount of energy required to break all intermolecular forces and change from the liquid phase to the gas phase). So it would essentially be the change in energy is equal to mcAT -- which is Mass * specific heat * change in temperature -- + the heat of fusion (amount of energy needed to completely melt ice into water)
Why is gravitational potential energy equal to kinetic ebergy?
Gravitational potential energy is not equal to kinetic energy:MGY doesn't always equal (1/2)mv2. This holds true in the CHANGE of gravitational potential energy being equal to the CHANGE in kinetic energy because of the Law of Conservation of Energy, Mass, and Charge.
How do you find kinetic energy if no final velocity is given?
Kinetic energy is equal to potential energy during the change
Why is the enthalpy of sublimation is equal to the sum of enthalpy of fusion and enthalpy of vaporization?
Enthalpy is a state function, and to a first approximation does not depend on temperature. So the change in enthalpy to go from solid to a gas directly (sublimation) at some temperature is equal to the sum of the enthalpies associated with going from a solid to a liquid (fusion) and going from a liquid to a gas (vaporization) at other temperatures.
The temperature at which the vapor pressure of a liquid is equal to the external pressure is the what?
The temperature at which the vapor pressure of a liquid is equal to the external pressure is the boiling point. Evaporation is when vaporization of an uncontained liquid occurs.

Does the mass of liquid affect the rate of temperature change?
Sure. Other things being equal, you need more energy to raise the temperature of a larger mass of liquid.
What does energy pressure mean?
Pressure energy per unit volume is equal to the pressure and per unit mass is equal to the density of the liquid. When an incompressible liquid flows out of a tank in which the pressure is maintained , the liquid under pressure possesses potential energy.
What energy is needed to change a material from solid to liquid?
Heat energy, usually. However, some substances will change states under the influence of UV or other radiation.AnswerThe energy needed to change a material from a solid to a liquid is called the 'latent heat of fusion', or just the 'heat of fusion'. It is equal to the amount of energy or heat given off by the same material to change it from a liquid back into a solid.Each material has its own heat of fusion. Take solid water (ice) at 0o Celsius, the freezing point. Water's heat of fusion is 79.71 calories per gram. That means that you will need to add 79.71 calories of heat to each gram of ice (solid water) to turn it into liquid water. Interestingly, once that's done, the water will still be at 0o Celsius! The heat was used just to change the water's state from solid to liquid. Once the ice is liquid, then any more heat added will increase the temperature of the liquid, and each calorie of heat will increase the water's temperature about 1o Celsius.This is a similar concept to a material's 'heat of vaporization', which is the amount of energy required to change a liquid to a gas.The amount of heat necessary to change a substance from a solid to a liquid or vice versa is commonly called the heat of fusion. It is more properly known as the standard enthalpy of fusion, or also the latent heat of fusion, or the enthalpy change of fusion. The specific temperature at which the change occurs is defined as the melting point of that substance. A link can be found below.The amount of energy a substance must absorb in order to change from a solid to a liquid is the heat of fusion. A change in which a system absorbs energy from its surroundings is endothermic change.
How do you calculate change in energy?
The change in potential energy is equal to mass*gravity*change in height

the Work-Energy Theorem states the work done is equal to the change in kinetic energy.

The change of water from a gas to a liquid?
The process of changing liquid water into a gas is called evaporation. Energy is added to the liquid water - generally in the form of heat. When enough energy is added, it allows the most energetic molecules at the surface of the liquid to break free of the liquid and enter the gas phase. The more energy that is added, the more water molecules will have enough energy to move into the gas phase. If enough energy is added, all the molecules will leave the liquid and from then on adding energy will just make the gas warmer. Another way to change liquid water into gas is to drop the pressure above the liquid. In this case, it takes less energy for the molecules in the liquid to get away from the liquid so some of them will already be energetic enough to get away. Any mass of liquid water will have a range of energies for the molecules, some will be low energy, others high energy with each collision between the molecules, they either gain or loose energy. If they gain enough energy, they can become energetic enough to escape the liquid as a gas. The higher the pressure, the more energy is required to become a gas. If the liquid water is in contact with some gas - air for example. The liquid will evaporate until the gas is saturated with water vapor. At that point the rate of water molecules dropping out of the gas back into the water (because they don't have enough energy to stay in the gas) is equal to the rate of water molecules escaping from the liquid to become gas. This point is also known as "equilibrium".
