Homework Help Overview

The discussion revolves around a problem involving the specific heat capacity of water and the calculation of temperature rise when a heater is used. The context includes a heater's power, the mass of water, and the duration of heating.

Discussion Character

  • Exploratory, Conceptual clarification, Mathematical reasoning

Approaches and Questions Raised

  • Participants discuss the need to identify the specific heat capacity of water and consider the units involved in the problem. There are inquiries about how to combine these units to derive a temperature change.

Discussion Status

Some participants have offered guidance on looking up specific heat capacity and considering the relevant equations. There is an acknowledgment of the importance of units in the calculations, but no consensus has been reached on the method to solve the problem.

Contextual Notes

One participant expresses a desire for a complete explanation, indicating a potential gap in understanding the underlying concepts. There is an emphasis on looking up information rather than providing direct answers.

a 210 heater is places in 2 kg of water. What temperature rise is produced if the heater is switched on for 200 seconds?

I need your help please.

You need to look up the specific heat capacity of water. Think about the units of specific heat capacity and the units of the quantities in the question. How can these all be combined to give you an answer in the correct units?
 
^ I have no idea about that i posted this for an answer with good explanation please
 
Well, it's easy to look up the specific heat capacity for water... just type it into Google or something. Then you need to think about how to use this information - again, the units will be a big hint and will tell you what the specific heat capacity represents.
 
Also try looking for the relevant equation. That should help you along the way to determining the answer.
