Specific Heat in Materials

Home » Experiments » Specific Heat in Materials

Introduction

In this experiment, we studied specific heat in materials to check which material would have the most amount of heat after being cooled and heated. And through this experiment, we can also determine the climate of different places affected by the materials around them.

Aim

To determine which kind of material would have the most amount of heat after being heated and cooled.

Theory

1. The amount of heat per unit mass required to raise the temperature of a material by one-degree celsius is known as the specific heat of that material.

2. The SI unit of specific heat is calorie/gram degree celsius.

Specific Heat in Materials

Requirements

1. Saltwater

2. Tap water

3. Sand

4. Soil

5, Oil

6. Corn

7. Car

8. Container

9. Two Thermometers

10. Lamp

Procedure

Step 1: Place the material in a container one by one after another.

Step 2: Add 2 thermometers to it—one on the surface and the other two cm deep.

Step 3: Put the lamp a couple of centimeters over the material.

Step 4: Turn on the lamp for one hour.

Step 5: Every five minutes, check both thermometers.

Step 6: Turn off the light after an hour.

Step 7: Then record the temperature after every five minutes.

Step 8: Repeat these steps three times for every material.

Observation

1. We observed that the soil and sand did not absorb much of the heat, and when they did, they released it easily.

2. Oil absorbs a lot of heat and releases it easily but not as fast as soil and sand.

3. Water absorbed less amount of heat and kept it for a longer duration of time.

Result

1. Oil accumulates the most amount of heat and does not release it.

2. Water comes second as it accumulates heat, a little less than oil, and also does not release it easily.

3. And the last ones are earth materials that release most of the absorbed heat.

Precaution

1. Measure the temperature correctly.

2. The first thermometer should be on the surface of the container, and another should be inside the container.

3. Experiment with every material one after another.

Conclusion

Through this experiment, specific heat in materials, we find that the place near the beach will have nice weather because the ocean will accumulate heat that will neither be so hot nor so cold. We have also seen which material absorbs most of the heat and which releases it.

VIVA Questions With Answers

Q.1 What was the aim of your experiment?

ANS. To determine which kind of material would have the most amount of heat after being heated and cooled.

Q.2 What do you understand about specific heat?

ANS. The amount of heat per unit mass required to raise the temperature of a material by one-degree Celsius is known as the specific heat of that material.

Q.3 Why does the area around the beachside have nice weather?

ANS. The area around the beach is neither too hot nor too cold because the ocean keeps in the heat.

ANS. Among earth material, water, and oil, earth material is the least heat absorbing.

Q.5 In which material has high heat absorbent and also keeps it for a longer period of time.

ANS. Oil has high heat absorbent and also keeps it for a longer period of time after this comes the water.
