## Specific Heat Worksheet Answer Key

If two objects at different temperatures are brought in contact with each other, energy is transferred from the hotter object that is, the object with the greater temperature to the colder lower temperature object, until both objects are at the same temperature. There is no net heat transfer once the temperatures are equal because the amount of heat transferred from one object to the other is the same as the amount of heat returned. One of the major effects of heat transfer is temperature change: Heating increases the temperature while cooling decreases it. The symbol c stands for specific heat , and depends on the material and phase. The specific heat is the amount of heat necessary to change the temperature of 1. Specific heat is closely related to the concept of heat capacity.

5). A g piece of iron at ° C is put into grams of water at ° C. What is the final temperature of the water and the iron? Page 2. Solutions.

## Specific Heat Example Problem

A body with mass 2 kg absorbs heat calories when its temperature raises from 20 o C to 70 o C. What is the specific heat of the body? Known :. Wanted : The specific heat c. Solution :.

Internal energy changes can be used to do work or transfer heat. The amount of work and heat must equal the change in internal energy. Find the molar specific heat at constant volume of the mixture, in terms of the molar specific heats and quantitites of the three separate gases. We additionally have the funds for variant types and afterward type of the books to browse. Many students find Class 11 Physics chapters difficult initially as the syllabus is a bit vast for students and the concepts are new.

### 11.2 Heat, Specific Heat, and Heat Transfer

The energy required to heat something is proportional to the mass and temperature change of the material. The proportionality constant is called specific heat. Photo by Johannes W on Unsplash. Specific heat is the amount of heat per unit mass needed to increase the temperature of a material by one degree Celsius or Kelvin. These three specific heat example problems will show how to find the specific heat of a material or other information involving the specific heat. Basically, this equation is used to determine the amount of heat added to a material to raise the temperature some amount or the amount lost as the material cools. This equation only applies to materials that stay in the same state of matter solid, liquid, or gas as the temperature changes.
