The amount of heat released when 100 grams of steam at 100 degrees Celsius
is converted into liquid water at 100 degrees Celsius is ____ J.
Heatvaporization=heatcondenstion=Hv*mass
Look up the heat of vaporization of water.
To calculate the amount of heat released when steam is converted into liquid water at the same temperature, you need to use the specific heat capacity and latent heat of vaporization of water.
Step 1: Calculate the heat released to cool the steam from 100°C to 100°C
The specific heat capacity of water is 4.18 J/g°C. Since the temperature doesn't change, there is no heat transferred.
Step 2: Calculate the heat released during condensation to convert steam to liquid water
The latent heat of vaporization of water is 2260 J/g. This means that 2260 Joules of heat is released for every gram of steam that condenses.
To find the total heat released, multiply the latent heat by the mass of the steam:
Total heat released = Mass of steam (g) x Latent heat of vaporization (J/g)
Given that the mass of steam is 100 grams, let's calculate the total heat released:
Total heat released = 100 g x 2260 J/g
Total heat released = 226,000 J
Therefore, the amount of heat released when 100 grams of steam at 100 degrees Celsius is converted into liquid water at 100 degrees Celsius is 226,000 Joules.
To find the amount of heat released when the steam is converted into liquid water, we need to use the equation:
Q = m * ΔH
Where:
Q is the amount of heat released (in joules),
m is the mass of the substance (in grams), and
ΔH is the enthalpy change (also known as the heat of vaporization or condensation) of the substance (in joules per gram).
In this case, we are given:
m = 100 grams
ΔH = heat of condensation of water = 2260 joules/gram (at 100 degrees Celsius)
Now we can substitute the values into the equation:
Q = 100 grams * 2260 joules/gram
Calculating:
Q = 226,000 joules
Therefore, the amount of heat released when 100 grams of steam at 100 degrees Celsius is converted into liquid water at 100 degrees Celsius is 226,000 joules.
