Calculating Heat Released during Condensation of 10g of Water Vapor at 100°C

To calculate the amount of heat released during the condensation of 10g of water vapor at 100°C, we can use the formula:

Q = Q1 + Q2 + Q3

Where: - Q1 = c1 * m * (t2 - t1) - Q2 = L * m - Q3 = c2 * m * (t3 - t2)

Given values: - m = 10g - t1 = 100°C (initial temperature) - t2 = 100°C (temperature during condensation)

Using the specific heat capacity of water (c1 = 2100 J/kg°C), the latent heat of vaporization of water (L = 334 * 10^3 J/kg), and the specific heat capacity of liquid water (c2 = 4200 J/kg°C), we can calculate the heat released during condensation.

Calculation: 1. Q1 = c1 * m * (t2 - t1) = 2100 * 0.01 * (100 - 100) = 0 J 2. Q2 = L * m = 334 * 10^3 * 0.01 = 3340 J 3. Q3 = c2 * m * (t3 - t2) = 4200 * 0.01 * (100 - 100) = 0 J 4. Q = Q1 + Q2 + Q3 = 0 J + 3340 J + 0 J = 3340 J

Therefore, the amount of heat released during the condensation of 10g of water vapor at 100°C is 3340 Joules.

Graph of Substance Temperature over Time

Creating a graph of the substance temperature over time would require specific data points or a mathematical function to represent the temperature change. If you have specific data points or a function, I can assist in creating the graph.
