Latent heat is the energy required for 1 kg of a substance to change?
Latent heat is the energy required for 1 kg of a substance to change ___________. phase
Energy needed to change material from solid to liquid?
heat is a mesure of energy the more energy the hotter it is so depending on its melting point is how much energy/heat is needed
What is needed to change water from a solid to a liquid?
A room temperature ubove 0 degrees centigrade.
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.
What is needed for matter to change phase?
Heat is needed for matter to change form eg: Melting, condensation, etc.
What temperature change is needed to change a liquid into a solid?
it depends on what type of liquid it is
What energy is needed to change a material from a liquid to a solid?
energy
What is the name of the energy needed to change a substance from a liquid to a gas?
The energy needed to change a substance from a liquid to a gas is called the enthalpy (or heat) of vaporization.
Why doesn't the temperature change fast during a phase change?
Basically because there is energy needed for the temperature to rise or become lower, but energy is also needed to change the phase, so instead of the energy being used to change the temperature, it is being used to change the phase, therefore temperature does not change.
Why considerable heat energy is needed to convert 1g of water into 1g of steam at 100c without any change in temperature taking place?
There is heat needed to transform the configuration of liquid water to gaseous state. This is change of state energy changes the configuration without changing the temperature.
What Heat of is the energy needed for a substance to change from liquid state to a gaseous state?
Heat of vaporization or enthalpy of vaporization. It is the additional energy, per unit mass, required after vaporization temperature (boiling point) is reached, to accomplish the change in state, from liquid to gas.
What energy needed to change 1 kg of liquid into gas at boiling point?
Thermal Energy
Latent heat is the energy required for 1 kg of a substance to change?
Latent heat is the energy required for 1 kg of a substance to change ___________. phase
Energy needed to change a material from solid to liquid?
It is the latent heat of liquefaction.
What type of heat energy is needed to change a material from a liquid to a gas?
endothermic
What is the energy needed for a substance to change from a liquid state to a gaseous state?
thermol
How do you you change a gas into a liquid?
You can change a gas into a liquid through cooling and condensation. Cooling a gas reduces the amount of energy between particles, which slows down movement. As particles lose energy they condense into a liquid. The temperature needed to create this depends on the gas in question.
