What is the latent heat of fusion?
The amount of energy it takes to boil a substance
What is the latent heat of fusion of water at atmospheric pressure?
The latent heat of fusion of water at atmospheric pressure is 334 joules per gram. This means that it takes 334 joules of energy to change 1 gram of ice at 0°C to 1 gram of water at 0°C.
What is the difference of heat capacity and latent heat?
Specific heat capacity (equation Q=mc��T) is the measure of the energy required in Joules to raise 1kg of a substance by 1.0 K (numerically equivalent to 1 C)Whereas, specific latent heat (equation Q=mL) is the amount of energy needed to change to the state of a substance either from solid to liquid, liquid to gas without changing its temperature.
What does specific latent heat of melting mean?
Specific latent heat of melting is the amount of heat energy required to change 1 kg of a substance from solid to liquid at its melting point without a change in temperature. It represents the energy needed for the phase change to occur, breaking intermolecular bonds to allow particles to move more freely.
Where does nuclear fusion take place in the sun?
Nuclear fusion takes place in the core of the sun.
What is the latent heat of fusion?
The amount of energy it takes to boil a substance
Why is latent heat of vapourisation higher than latent heat of fusion?
latent heat of vapourisation is the heat energy required to change 1 kg of a liquid to gas at atmospheric pressure at its boiling point where latent heat of fusion is the amount of heat energy required to change 1 kg of solid to liquid at its melting point so that is why latent heat of vapourisation higher than latent heat of fusion.
How does specific latent heat of water vary with temperature?
Latent heat of water is the heat required to change its state at a particular temperature BECAUSE of the pressure at which the water is at at the point of fusion or evaporation.The latent heat is not affected by temperature (in fact there is no temperature change during absorption of latent heat) it is affected by the pressure acting on a substance. As the pressure increases, the latent heat (of evaporation) decreases, consequently with the change in pressure there is also a different temperature at which the evaporation takes effect, higher pressure, higher temperature at the evaporation point.
What is the latent heat of fusion of water at atmospheric pressure?
The latent heat of fusion of water at atmospheric pressure is 334 joules per gram. This means that it takes 334 joules of energy to change 1 gram of ice at 0°C to 1 gram of water at 0°C.
Nuclear fusion takes place?
I could answer is the question was more specific.
Why does an ice cube stay at 0c for a long time?
The enthalpy of fusion, or Specific heat of fusion/melting is the temperature that it takes for a substance to freeze/melt. Generally it is much greater than it would ordinarily take for the substance to increase 1 degree Celsius in either solid or liquid phase. So, while at the freezing/melting point, the substance can absorb energy without changing the temperature during the state change.
What is the difference between heat of fusion and heat of vaporization?
Latent heat is the amount of thermal energy required to change the phase of a substance. Latent heat of fusion is the amount of energy needed to change it from a solid to liquid or a liquid to solid, and the latent heat of vaporization is the thermal energy needed to change from a liquid to gas or a gas to liquid. For example, in the equation Q = mL, Lfusion (latent heat of fusion) for water is 75.5 cal/gram. Lvaporization (latent heat of vaporization) for water is 539 cal/gram. Substances have different latent heats.
What is the difference of heat capacity and latent heat?
Specific heat capacity (equation Q=mc��T) is the measure of the energy required in Joules to raise 1kg of a substance by 1.0 K (numerically equivalent to 1 C)Whereas, specific latent heat (equation Q=mL) is the amount of energy needed to change to the state of a substance either from solid to liquid, liquid to gas without changing its temperature.
A change of phase takes place at a constant?
A change of phase takes place at a constant temperature and pressure. During a change of phase, the substance absorbs or releases latent heat without a change in temperature.
In what part of the sun does fusion takes place?
Fusion takes place in the core of the sun.
What does specific latent heat of melting mean?
Specific latent heat of melting is the amount of heat energy required to change 1 kg of a substance from solid to liquid at its melting point without a change in temperature. It represents the energy needed for the phase change to occur, breaking intermolecular bonds to allow particles to move more freely.
What is a similarity between heat fusion and heat solidification?
When changing from a solid to a liquid, melting, the heat absorbed is called the heat of fusion. When the reverse takes place, freezing, it is called the heat of solidification. For a single substance they are the same.
