Method:
The apparatus consists of a metal ball which fits exactly through a ring attached to a stand when both are at room temperature.
Heat the ball using a Bunsen Burner for a few minutes and then try to pass it through the ring.
Observations:
The ball does not pass through the ring when it is hot.
leave the ball on the ring and allow it to cool for some time. The ball will now pass through the ring
Conclusions:
This proves that solids expand on heating and contract on cooling.
What else can I help you with?
Give an experiment to show that air a bad conductor of heat?
You can conduct an experiment by heating a metal rod at one end and touching it to a balloon filled with air. The balloon will not pop immediately because air is a poor conductor of heat, so the heat does not transfer quickly enough to cause the balloon to burst.
Who discovered invisible light?
William Herschel is credited with discovering invisible infrared radiation in 1800. He conducted an experiment using a prism to show that different colored filters were heating up at different rates, proving the existence of light beyond the visible spectrum.
How will you show by experiment that air is present?
One way to demonstrate the presence of air is to create a vacuum inside a closed container and observe that a vacuum pump is required to remove the air. Another method is to perform the candle jar experiment, where a lit candle placed in a jar is extinguished due to the depletion of oxygen, showing the presence of air. Alternatively, using a balloon over the mouth of a bottle containing baking soda and vinegar can show the production of gas (carbon dioxide) as a result of the chemical reaction, indicating air's presence.
What did Einstein show by his train experiment?
Einstein's train experiment demonstrated the principle of time dilation, where time is experienced differently by observers in motion relative to each other. This experiment illustrated how time slows down for objects in motion, and is a key concept in his theory of special relativity.
What are the key findings and implications of Young's double slit experiment?
The key findings of Young's double slit experiment show that light behaves as both a wave and a particle. This duality challenges traditional ideas about the nature of light. The implications of this experiment have had a significant impact on the development of quantum mechanics and our understanding of the fundamental nature of the universe.

How should you show that yeast was responsible for making the dough rise?
To show that yeast was responsible for making the dough rise, you can conduct an experiment where you prepare two batches of dough- one with yeast and one without. Allow both doughs to rise, and observe that the dough with yeast rises significantly more due to the yeast's fermentation process producing gases that make the dough expand.
How could you design an experiment to show how a fault is formed?

What did Dalton's experiment show?
He showed that you can show the true show when you show it correctly.
What is the difference between positive and negative control in an experiment?
In an experiment, a positive control is used to show that the experiment can detect a specific response, while a negative control is used to show that the experiment does not detect a response when it should not.
How can you prove by experiment to show that starch is produced in the presence of sunlight?
Aim of an experiment to show that starch is produced in the presence of sunlight
How will you show that gases are dissolved in water?
we can show that gases are dissolved in water by showing the gas escaping in the form of bubbles.
What experiment do you perform to show that bark cells are impervious to gases and smoke?
To demonstrate that bark cells are impervious to gases and smoke, you can conduct a simple experiment using a piece of bark from a tree. Place the bark in a sealed container and introduce a smoke source, such as a lit incense stick, outside the container. Observe whether any smoke penetrates the bark into the enclosed space. If no smoke is detected inside, this indicates that the bark cells effectively block the passage of gases and smoke, confirming their impervious nature.
What is used in an experiment to show that the results of an experiment are a result of the condition being tested?
Control
What is the difference of a model or an experiment?
A model is to show something and it does not have a control group, like a experiment.
