What is dimension of enthalpy?
The correct dimensional formula of latent heat is MoL2T2.
Why you measure enthalpy in H instead of H?
The total enthalpy of a system is called "H." That stands for "total enthalpy." It is not a measure of enthalpy. Enthalpy is measured in the SI or metric system in joules (abbreviated as J) or in customary units such as British Thermal Unit (BTU) or calories (cal).
What is the equation for calculating the change in enthalpy of a system during a chemical reaction?
The equation for calculating the change in enthalpy of a system during a chemical reaction is H H(products) - H(reactants), where H represents the change in enthalpy, H(products) is the enthalpy of the products, and H(reactants) is the enthalpy of the reactants.
What is the relationship between constant pressure enthalpy and the changes in a system's energy content during a process?
Constant pressure enthalpy is a measure of the energy content of a system at a constant pressure. During a process, changes in the system's energy content are reflected in the enthalpy changes. The relationship between constant pressure enthalpy and changes in energy content is that they are directly related - as the enthalpy changes, so does the energy content of the system.
Is Delta S is the change in enthalpy a measure of randomness?
No, ΔS (change in entropy) and ΔH (change in enthalpy) are not measurements of randomness. Entropy is a measure of the disorder or randomness in a system, while enthalpy is a measure of the heat energy of a system. The change in entropy and enthalpy can be related in chemical reactions to determine the overall spontaneity of the process.

How do you make a sentence for enthalpy?
Enthalpy is a thermodynamic property of a thermodynamic system.
How can the concept of quality be utilized to determine the enthalpy of a system?
The concept of quality can be used to determine the enthalpy of a system by considering the composition of the system and the amount of heat added or removed. Enthalpy is a measure of the total energy of a system, and by understanding the quality of the components in the system, one can calculate the enthalpy changes that occur during processes such as heating or cooling. By analyzing the quality of the components and the heat transfer involved, one can determine the enthalpy of the system.
Is enthalpy conserved in a closed system undergoing a chemical reaction?
Enthalpy is not conserved in a closed system undergoing a chemical reaction.
What is the equation for calculating the change in enthalpy of a system during a chemical reaction?

What is absoulte temperature?
Absolute temperature is a temperature measured on a scale that starts at absolute zero, where particles have minimal motion. The most common absolute temperature scale is the Kelvin scale, where 0 K is equivalent to -273.15 degrees Celsius. Absolute temperature is used in thermodynamics and physics to describe the energy of a system.
What are absolute and relative coordinates system?
In the absolute coordinate system, positions are measured from a fixed reference point, such as the origin (0,0). In contrast, relative coordinates are measured in relation to a starting point, like a previous position or object. Absolute coordinates provide definitive positions, while relative coordinates are used to describe movements or relationships between objects.
What is ordinary and absolute temperature scale in SI system and English system?
In the SI system, the absolute temperature scale is measured in Kelvin (K), where 0 K represents absolute zero, the theoretical point where all thermal motion ceases. The ordinary temperature scale in the SI system is Celsius (°C), which is based on the freezing and boiling points of water. In the English system, temperature is typically measured in degrees Fahrenheit (°F) for ordinary use, while absolute temperature is often expressed in Rankine (°R), where absolute zero is 0 °R and the size of the degree is the same as that of Fahrenheit.
What is the relationship between air enthalpy and the efficiency of a heating and cooling system?
The relationship between air enthalpy and the efficiency of a heating and cooling system is that the enthalpy of the air affects the amount of energy needed to heat or cool it. Higher enthalpy levels require more energy to change the temperature of the air, which can impact the efficiency of the system. In general, a heating and cooling system will be more efficient when working with air at lower enthalpy levels.
Which law states that absolute zero cannot be reached?
The Third Law of Thermodynamics states that absolute zero cannot be reached. This law asserts that as a system approaches absolute zero, its entropy approaches a minimum value but never reaches zero.
