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.
The equation to calculate the amount of energy needed to change state is: Q = m * L, where Q is the energy needed, m is the mass of the substance, and L is the specific latent heat of the substance.
Heat of transformation is the amount of heat absorbed or released during a phase change of a substance, such as melting, freezing, vaporization, or condensation. It is the energy required to change the state of a substance without changing its temperature.
Change of state of a substance is a physical property!
No. Roughly speaking, "specific gravity" is equivalent to density, i.e., mass divided by volume. If a substance changes its state, its volume will change, but its mass won't change - therefore, the density - the result of the division - will also change.
Specific heat and latent heat are both properties of a substance that determine how it absorbs or releases thermal energy. Specific heat refers to the amount of heat required to raise the temperature of a substance by a certain amount, while latent heat is the amount of heat needed to change the state of a substance without a change in temperature. In thermal energy transfer, specific heat affects the temperature change of a substance, while latent heat is involved in phase changes such as melting or boiling.
It is the amount of energy required to change the state of 1kg of a substance with no change in temperature.
The equation to calculate the amount of energy needed to change state is: Q = m * L, where Q is the energy needed, m is the mass of the substance, and L is the specific latent heat of the substance.
Is the amount of energy that is required to change the temperature of 1kg of a substance by 1 degree Celsius with no state change.
True. The state of a substance, such as solid, liquid, or gas, depends on the amount of thermal energy it possesses. Increasing thermal energy can change the state of a substance, such as melting a solid into a liquid or evaporating a liquid into a gas.
Latent heat- the amount of heat required by a system/ substance to change phase. It's also heat absorbed or radiated during a change of phase at a constant temperature and pressure.
change of state
Heat of transformation is the amount of heat absorbed or released during a phase change of a substance, such as melting, freezing, vaporization, or condensation. It is the energy required to change the state of a substance without changing its temperature.
change is complete
The state of matter is related to the amount of energy in a substance through the kinetic energy of its particles. As a substance gains energy, its particles move faster, causing a change in state (solid to liquid, liquid to gas) as the intermolecular forces are overcome. This change in energy affects the arrangement and movement of particles, determining the state of matter.
False. The temperature of a substance remains constant during a change in state until all of the substance has completed the phase change.
This is called a change in the physical state of the substance. For example formation of ice from water is a change in the physical state of water.
