Solving Latent Heat and Thermodynamics Problems: Explained for 9th Graders

Click For Summary

Homework Help Overview

The discussion revolves around solving problems related to latent heat and thermodynamics, particularly aimed at a 9th-grade understanding. Participants are exploring the concepts of phase changes and energy calculations involved in these processes.

Discussion Character

  • Exploratory, Conceptual clarification, Problem interpretation

Approaches and Questions Raised

  • Participants inquire about specific types of problems related to phase changes and energy calculations. There is a request for simpler explanations suitable for a younger audience, as well as questions about the general approach to thermodynamics problems.

Discussion Status

The conversation is ongoing, with participants sharing their thoughts on the nature of latent heat problems and the methods typically used to solve them. Some guidance has been offered regarding the use of equations and tables for finding latent heat, but no consensus has been reached on specific problem-solving strategies.

Contextual Notes

Participants are discussing the need for clarity on calculating energy changes during phase transitions, with specific examples mentioned. There is an acknowledgment that the problems may require knowledge of equations and data from tables, but the exact details of the problems remain unspecified.

how do you slove latent heat problems?

also is there a easier way to slove thermodyamics problem?

explain in a way a way that a 9th grader like me can understand.

thanks

What kind of problems?
 
i need to know the Phase change of objects and how to caculate the Joules of energy needed for the changes.
 
Generally, at that level, such problems ask for final temperature and you get the latent heat from a table. But perhaps you could be more specific...?
 
yeah

first off
"also is there a easier way to slove thermodyamics problem?"
simply put...no

you solve them by using the equation

Q=cm(delta)T

i would like to know more about the heat exchange in mixtures and
example would be like:

How much heat energy is required to change?
a) 2.0kg of ice at 0 C to water at 0 C?

b) 500g of water at 100 C to steam at 100 C?
