# What is the molar heat of solidification of water?

When 1 mol of water at 0°C freezes to

**ice**at 0°C, 6.01 kJ of heat are released into the surroundings. The molar heats of fusion and solidification of a given substance can be used to calculate the heat absorbed or released when various amounts are melted or frozen.A.

### What is the molar heat of vaporization of water?

It is only for one mole of substance boiling. The

**molar heat of vaporization**is an important part of energy calculations since it tells you how much energy is needed to boil each mole of substance on hand. The units for the**molar heat of vaporization**are kilojoules per mole (kJ/mol).#### What is the molar heat of sublimation?

The molar heat (or enthalpy) of sublimation is the amount of energy that must be added to a mole of solid at constant pressure to turn it directly into a**gas**(without passing through the liquid phase).#### What is the molar heat of vaporization of ethanol?

The molar heat of vaporization of ethanol is 39.3 kJ/mol and the**boiling**point of ethanol is 78.3°C. Calculate ΔS for the vaporization of 0.50 mol ethanol.#### What is the heat of vaporization of water in calories per gram?

Similarly, while**ice**melts, it remains at 0 °C (32 °F), and the liquid water that is formed with the latent heat of fusion is also at 0 °C. The heat of fusion for water at 0 °C is approximately 334 joules (79.7 calories) per gram, and the heat of vaporization at 100 °C is about 2,230 joules (533 calories) per gram.

### What is the molar heat of fusion of ice?

The

**molar heat of fusion of ice**is 6.01 kJ/mol.#### What is the heat of fusion of ice?

The enthalpy of**fusion**of a substance, also known as (latent)**heat of fusion**, is the change in its enthalpy resulting from providing energy, typically**heat**, to a specific quantity of the substance to change its state from a solid to a liquid, at constant pressure.#### What is the molar heat of sublimation?

The molar heat (or enthalpy) of sublimation is the amount of energy that must be added to a mole of solid at constant pressure to turn it directly into a**gas**(without passing through the liquid phase).#### What is the value of the specific latent heat of fusion of ice?

1 calorie = 4.186 J.

Latent heat of vaporization of water = 539 cal/g = 2256 kJ/kg.

Latent heat of fusion of water = 79.5 cal/g =**333 kJ/kg**.

Specific heat of water = 1 cal/g = 4.19 kJ/kg.
