The water rises in the candle experiment because the heat from the candle causes the air inside the container to expand, pushing some of the air out. As the air cools down, it contracts, creating a lower pressure inside the container. This lower pressure causes the water to rise up into the container to equalize the pressure.
What else can I help you with?
Does the size of a candle affect how fast it will burn?
Yes, the size of a candle can affect how fast it burns. A larger candle typically has more wax, so it may burn for a longer period of time than a smaller candle. However, other factors such as the type of wax, wick size, and environmental conditions can also influence the burning rate of a candle.
Why does smoke rise rather then fall from a lighted candle?
floating candles float higher in the water a they burn because as the candle burns it is decreasing its mass and deplacing less water, so it floats higher....but im not sure? its burning off the wax and makes the candle more buoyant which means it just burns off weigh... sorry for answering so late... enjoy
What will happen when a lighted candle is placed under one of the bags?
The bag above the candle will heat up as the flame warms the air inside, causing it to expand and rise. This will create a convection current, pulling the bag up due to the buoyant force.
What variable in a experiment is a water temperature?
The variable in an experiment that is being measured or tested is usually referred to as the independent variable. In the case of testing the effect of water temperature, the independent variable would be the water temperature itself.
How fast do bubbles rise in water?
The speed at which bubbles rise in water depends on factors such as the size of the bubble, water temperature, and water density. On average, bubbles can rise at a speed of about 2-3 centimeters per second in still water. However, in turbulent water or with smaller bubbles, the speed of rise can be faster.
What is the principle used in water candle experiment?
The principle used in the water candle experiment is the concept of capillary action, where the water is drawn up the wick of the candle due to adhesion and cohesion forces. As the flame burns, the heat evaporates the water causing it to rise through the wick and fuel the candle's flame.
How long can a candle burn under beakers of different sizes?
This delightfully simple experiment may be used to estimate the percentage of oxygen in the air. Assumption is that all the Oxygen is consumed. Mount candle on a small watchglass floating on water, light the candle, and place an inverted beaker over the whole to create a water seal. Measure the rise of the water inside the beaker.
What change in the water level occurs when you hold Erlenmeyer flask over a candle in a pan of water?
When you hold an Erlenmeyer flask over a candle in a pan of water, the water inside the flask heats up and expands, causing the water level in the flask to rise. This is due to the expansion of the water molecules as they gain thermal energy from the heat source.
How does a candle look like it is burning inside a glass of water?
When a candle is placed inside a glass of water, the water absorbs the heat produced by the flame. This heat causes the water to evaporate and rise above the flame, creating the illusion that the candle is burning inside the water. In reality, the candle is burning above the water level.
Why did the water rise in the beaker When the candle burned out?
The water rose in the beaker because as the candle burned, it consumed oxygen in the air inside the beaker. This created a partial vacuum, causing the water to be pushed up into the beaker due to the air pressure outside.
How does a candle powered hot air balloon work?
A candle-powered hot air balloon works by heating the air inside the balloon with a suspended candle flame. As the air inside the balloon is heated, it becomes less dense and rises, creating lift. The balloon will continue to rise until the air inside cools down or the flame is extinguished.
What is a good science experiment not science fair project that includes fire and you can do in class?
Take a deep, tranparent bowl. Stick a candle in the middle of it. Fill it almost to the brim with water while making sure the candle doesn't fall over. Cover the candle with a glass. The water outside the glass will get sucked in. Whoops! Light the candle before you put the glass on top By Reimond Costa aged 10
What is the objective of generating electricity from candle?
None, other than doing an interesting experiment.
How do you find the rate at which a candle burns?
you experiment with different types of candles
Will putting water in a candle ruin it?
NO, it will not ruin it!! It does not hurt the candle!! Only if you use water to blow out the candle over and over again! The water acks like wax once it hits the wax!!
What is the purpose of calcium chloride in burning candle investigation?
Calcium chloride is used in a burning candle investigation to absorb moisture and prevent any water vapor from affecting the results. This helps ensure that any changes observed during the experiment are due to the combustion of the candle wax and not influenced by external factors like humidity.
When you put water in a plate then put a candle in the water and light it then put a cup over it and the water goes into the cup what is this called?
This is known as an experiment demonstrating the concept of water displacement and the principle of atmospheric pressure. When the candle burns inside the cup, it consumes oxygen, reducing air pressure inside the cup. The higher atmospheric pressure outside the cup forces the water up into the cup to balance the pressure difference.
