Why does a candle gets extinguished when 2 candles of different sizes and same thickness are covered by same bell jar?
As they burn, the candles are using up oxygen under the bell jar. They produce carbon dioxide as a result. Carbon dioxide is havier than air and so collects at the bottom of the bell jar. The lower candle goes out when the level of carbon dioxide gets high enough to "drown" that candles flame - that is, block it from any oxygen. However, it is possible that, before that happens, so much of the oxygen in the bell jar is used up that the remainder is not enough to sustain a flame.

Is there a chart to calculate the amount of stone that is needed at different thickness?
Yes, there are charts and calculators available that help estimate the amount of stone needed based on the area to be covered and the desired thickness of the stone layer. These resources typically provide conversions and guidelines for various types of stone, allowing users to input dimensions and receive a calculated volume or weight. It's important to consider factors such as the type of stone and its specific weight when using these tools. You can often find these charts on landscaping or construction websites.
How many Tonnes of asphalt in 1 cm?
The weight of asphalt in 1 cm thickness depends on its density, which typically ranges from 2.2 to 2.4 tonnes per cubic meter. Therefore, for a 1 cm (0.01 meters) thickness, you would have approximately 22 to 24 tonnes of asphalt per 100 square meters. To calculate the total weight, you would multiply the density by the area covered in square meters.
Is the area covered by a persons palm described as the area covered by a tires footprint?
No, the area covered by a person's palm is not typically described as the area covered by a tire's footprint. A person's palm is generally smaller and has a different shape compared to a tire's footprint, which is larger and designed to distribute weight and provide traction. While both can be considered contact areas with surfaces, their dimensions and purposes differ significantly.
How much plaster is needed to cover a square meter?
The amount of plaster needed to cover a square meter typically depends on the thickness of the application. Generally, for a standard layer of plaster, you would require about 1.5 to 2 kilograms of plaster per square meter for a thickness of around 10 mm. However, this can vary based on the type of plaster and the surface being covered, so it's always best to consult manufacturer guidelines for specific products.
How do you calculate consumption of mortar in blockwork?
To calculate the consumption of mortar in blockwork, first determine the total area of the blocks being laid. Then, estimate the joint thickness (typically between 10-15 mm) and calculate the volume of mortar needed for the joints by multiplying the total area by the joint thickness. Finally, convert this volume to bags of mortar based on the volume covered by one bag, usually provided by the manufacturer. Adjust for wastage, typically around 10%.
When a burning candle is covered with a glass it get extinguished why?
When a burning candle is covered with a glass, the oxygen within the covered space gets depleted as the flame consumes the available oxygen. Without sufficient oxygen, the candle flame is unable to sustain combustion and gets extinguished.
Why does a burning candle get extinguished when covered with a tumbler?
Fire needs oxygen to burn and when the tumbler covers the fire it uses up all the oxygen in the little space quickly and is extinguished.
Why does the topsoil differ in thickness in different part of Canada?
because Canada is covered with wet- climate soil that are prone to leaching.
Why does topsoil differ in thickness in different parts of Canada?
because Canada is covered with wet- climate soil that are prone to leaching.
Why does a lighted candle get extinguished when covered?
A lighted candle gets extinguished when covered because it is deprived of oxygen, which is necessary for combustion. The flame consumes the available oxygen in the enclosed space, and as the oxygen levels drop, the flame eventually can no longer sustain itself and goes out. Additionally, the buildup of carbon dioxide from the burning wick can also contribute to extinguishing the flame.
What is the thickness of a phone?
It will vary according to the area covered by the book. A standard phone book is generally 2.5 inches.
How much mortar do I need for my upcoming project?
To determine how much mortar you need for your project, calculate the area to be covered and the thickness of the mortar layer. Multiply the area by the thickness to find the volume of mortar needed.
What happen if a big and a small burning candle is covered with a big jar?
Once the oxygen was used up, both candles would go out.
Which candles drip the least so a child doesn't eat the wax?
Soy wax candles are virtually drip free. Less expensive wide pillar candles made with a softer inner core wax covered by a firmer outer wax burn inward, thus melting from within. Tall tapers, a favorite of weddings and other special occasions are also dirpless.
What is the difference between depth and thickness?
Depth refers to the distance from the top or surface to the bottom of an object, while thickness refers to the measurement of the distance between opposite sides of an object. In simpler terms, depth is vertical measurement while thickness is horizontal measurement.
What type of landscape is Antarctica considered?
About 98% of Antarctica is covered by ice, which averages at least 1.6 kilometres (1.0 mi) in thickness.
Why do candles go out when covered?
because the air current carries away the oxygen, which is needed for a candle to burn.
