Final answer:
The total heat lost by the steam as it condenses and reaches 50°C can be calculated using the specific heat of steam and the equation Q = mcΔT. However, without the specific latent heat of vaporization, it is not possible to calculate the complete heat lost. Thus, the correct answer is D. None.
Step-by-step explanation:
The total heat lost by the steam as it condenses and reaches 50°C can be calculated using the specific heat of steam and the equation Q = mcΔT, where Q is the heat, m is the mass, c is the specific heat, and ΔT is the change in temperature.
- First, find the heat released during condensation. Since steam condenses at 100°C, the initial temperature is higher than the final temperature of 50°C. Therefore, the heat released can be calculated as Q = mcΔT = (mass of steam)(specific heat of steam)(final temperature - initial temperature).
- Additionally, consider the heat released during the phase change from steam to water. It is important to note that during this phase change, a significant amount of heat is released. This heat can be calculated as the specific latent heat of vaporization multiplied by the mass of steam. However, the information provided does not contain the specific latent heat of vaporization, making it impossible to calculate the exact amount of heat released during this phase change.
Based on the information provided, the correct answer is D. None. The question asks for the total heat lost by the steam, but without the specific latent heat of vaporization, it is not possible to calculate the complete heat lost.
