Homework Help Overview

The discussion revolves around two heat transfer problems involving a silver spoon and spent steam from an electric generating plant. The original poster seeks assistance in calculating the heat absorbed by the spoon and the heat removed by cooling tower water.

Discussion Character

  • Exploratory, Conceptual clarification, Mathematical reasoning

Approaches and Questions Raised

  • Participants discuss the need for the specific heat of silver to solve the first problem and question how to apply this information. There is also mention of the relationship between heat transfer and temperature change.

Discussion Status

The discussion includes attempts to clarify the necessary physical constants and references to the original poster's textbook for further information. Some participants have noted the importance of understanding the underlying concepts, but there is no explicit consensus on the approach to take.

Contextual Notes

Participants highlight the need for specific heat values, suggesting that the original poster may need to reference external sources or their textbook for this information. There is an indication that the original poster feels uncertain about the concepts involved.

Homework Statement



a 50.0g silver spoon at 20.0*C is placed in a cup of coffee at 90.0*c. how much heat does the spoon absorb from the coffee to reach a temperature of 89.0*C

HOW DO I SOLVE THIS!

and also this question

Spent Steam from an electric generating plant leaves the turbines at 120.0*C and is cooled to 90.0*C liquid water by water from a cooling tower in a heat exchanger. how much heat is removed by the cooling tower water for each kilogram of spent steam?

You need the value of a physical constant known as the specific heat of that metal (silver). If it's not in your textbook, use google.

so how do i solve it i really don't know this at all.
 
heat absorbed from the coffee = [Solution deleted by moderator.]

While the OP has seen the solution that was posted, I'll just remark that there should be a discussion of this topic in the OP's physics textbook, along with the formula relating heat and temperature change, plus a list of specific heat values for different materials.
