Question

Write an experiment to prove green house effect n temperature

Answer 1

What You Need:

Two thermometers
A notebook
Pencil or pen
A clear container, such as a jar
Watch or clock
A sunny area, either outside or inside

What You Do:

Lay the thermometers in direct sunlight. Let them sit in the sun for three minutes.Open up a page of the notebook and draw two columns, one labeled "Thermometer A" and one labeled "Thermometer B."After the three minutes have passed, read and record the time and thermometer temperatures in the notebook.Place one of the thermometers in the jar or container and seal. Make sure the lid doesn't cast a shadow on either thermometer!Record the temperature of the thermometers every minute for ten minutes.Discuss how the container affected the temperature of thermometers. How did the temperature inside the container change compared to outside the container?

What's Going On?  The thermometer outside of the container is constantly being exposed to air that is constantly changing temperature, as the warm air mixes with passing cooler air. The air inside the container is trapped and can't mix with the cooler surrounding air–it just gets warmer as the sunlight heats it up. A greenhouse works in a similar way; solar energy in the form of light creates thermal energy, or heat, that can't escape through the glass.

This activity mirrors how a greenhouse works, but it's not exactly the same as the greenhouse effect that is taking place in the Earth's atmosphere. A complex interaction between light, heat, and chemicals make up the greenhouse effect and the chemicals known as "greenhouse gases" in the environment. They cause the temperature of the Earth to be warmer than it would be without them, much like the glass in a greenhouse, or the jar in this activity.

Answer 2

Answer:

This verifies the greenhouse effect (greenhouse gases such as $CO}_{2}$ increases the temperature of the earth.

Explanation:

Aim :

To, verify the greenhouse effect on temperature.

Apparatus :

Two glass bottles, two corks, two thermometers, vinegar, baking soda, high voltage lamp

Procedure:

1. Bring $100 \mathrm{ml}$ vinegar and a tablespoon of baking soda in one bottle and close its mouth with a cork.

2. Insert the thermometer into the bottle through the cork such that the bulb of the thermometer should not connect to the material in the bottle.

3. Insert another thermometer into the empty bottle via the cork.

4. Keep these two bottles opposing a high voltage bulb such that both bottles obtain an identical amount of temperature.

5. Note down the initial temperatures and record the temperatures for an hour.

Observation:

1. We can observe that the vinegar and baking soda in the first bottle react with each other to create$\mathrm{CO}_{2}$.

2. This$\mathrm{CO}_{2}$absorbs and maintains more heat from the bulb than the normal air in the second bottle.

Inference:

This verifies the greenhouse effect (greenhouse gases such as $CO}_{2}$ increases the temperature of the earth.
