What is the dimensional formula of latent heat and specific heat?
The dimensional formula of latent heat is [L^2 T^-2], which signifies energy per unit mass. The dimensional formula of specific heat is [L^2 T^-2 K^-1], representing the amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius.
What is latent heat of fusion of a solid?
The latent heat of fusion of a solid is the amount of heat energy required to change a solid into a liquid at its melting point without changing its temperature. It is also known as the heat of fusion and is typically measured in joules per gram (J/g).
What is the specific latent heat of fusion of mercury?
The specific latent heat of fusion of mercury is about 11.28 kJ/kg. This value represents the amount of energy required to change a unit mass of solid mercury at its melting point to liquid mercury at the same temperature, without changing its temperature.
What is the difference of heat capacity and latent heat?
Heat capacity is the amount of heat energy required to raise the temperature of a substance by a degree Celsius, while latent heat is the amount of heat energy needed to change the phase of a substance without a change in temperature. Heat capacity depends on the substance's mass and specific heat capacity, while latent heat is specific to the phase change of the substance.
Can heat be measured in degrees Fahrenheit?
Yes, heat can be measured in degrees Fahrenheit, which is a unit of temperature commonly used in the United States.
What unit is specific heat measured in?
In SI, specific heat capacity is measured in joules per kilogram kelvin.
What is the dimensional formula of latent heat and specific heat?
The dimensional formula of latent heat is [L^2 T^-2], which signifies energy per unit mass. The dimensional formula of specific heat is [L^2 T^-2 K^-1], representing the amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius.

What is the specific latent heat of fusion of mercury?
The specific latent heat of fusion of mercury is about 11.28 kJ/kg. This value represents the amount of energy required to change a unit mass of solid mercury at its melting point to liquid mercury at the same temperature, without changing its temperature.
What does the latent heat of fusion measured?
The energy required to melt a substance
What is dimension of enthalpy?
The dimension of enthalpy is energy per unit mass (J/kg) or energy per unit amount of substance (J/mol). It has the same dimensions as energy, which is measured in joules (J).
What is the difference of heat capacity and latent heat?
Heat capacity is the amount of heat energy required to raise the temperature of a substance by a degree Celsius, while latent heat is the amount of heat energy needed to change the phase of a substance without a change in temperature. Heat capacity depends on the substance's mass and specific heat capacity, while latent heat is specific to the phase change of the substance.
Can heat be measured in degrees Fahrenheit?
Yes, heat can be measured in degrees Fahrenheit, which is a unit of temperature commonly used in the United States.
Specific heat is measured in?
Specific heat is measured in units of energy per unit mass per degree Celsius (J/kgĀ°C or cal/gĀ°C). It indicates the amount of heat energy required to raise the temperature of a specific amount of a substance by one degree Celsius.
Correct units to determine specific heat?
Specific heat is typically measured in units of J/(gĀ°C) or J/(gK), which represent the amount of heat required to raise the temperature of one gram of a substance by one degree Celsius or one Kelvin, respectively. It is a measure of the substance's ability to store thermal energy.
What is the quantity of heat required to raise unit mass?
The quantity of heat required to raise the temperature of a unit mass of a substance by one degree Celsius is known as specific heat capacity. It is a constant value for each substance and is measured in J/kgĀ°C.
Is latent heat of vaporisation fixed?
No, the latent heat of vaporization is not fixed and can vary depending on the substance. It represents the amount of energy required to change a unit mass of a substance from liquid to gas at a constant temperature and pressure.
