What would happen if you light a hand warmer on fire?
it depends. If you just get the soil, it will work as an alternate gunpowder.(don't try it!)However, if you light the paper or whatever too, it will make a small detonator that just make smoke that could kill you.
How did 'volcano' get its name?
The "volcano" gets its name from the Latin word volcanus(fire, flames). TheRoman god of fire and forges was Vulcan (comparable to the Greek God Hephaestus).
Why do room heaters have polished reflectors?
Room heaters have polished reflectors to maximize the efficiency of heat distribution. The polished surface reflects heat waves away from the heater, directing them towards the desired area to be heated. This helps to prevent heat loss and ensures that more heat is directed towards the intended space, resulting in quicker and more effective heating.
There are 18 hundreds in 1,800. Simply divide 1,800 by 100 and the answer is 18.
What is the most branches of science?
There is no definitive answer to which branch of science is the most extensive, as it ultimately depends on how one defines "branch." However, some of the major branches of science include physics, chemistry, biology, astronomy, geology, and environmental science. Each of these branches encompasses numerous subfields and disciplines, making them vast and complex in their own right.
Physiological limits refer to the boundaries of what the human body can sustain in terms of physical and biological functions. These limits vary among individuals and can be influenced by factors such as age, genetics, and training. Pushing beyond these limits can lead to exhaustion, injury, or other health complications.
Does it really take 24 hours for earth to rotate on its axis?
No. It takes 24 hours to bring the observed position of the sun (on average throughout the year) to the same place in the sky. Because the earth is going around the sun, each six months the sun is south at midday but pointing in an exactly opposite direction to the stars as it was 6 mths before. The rotation period is about 4 mins less than 24 hours.
How many quarters are there in a 73 dollars?
Oh, dude, seriously? Alright, let me do the math for you. There are 292 quarters in 73 dollars. Each quarter is worth 25 cents, so you just divide 73 by 0.25. Easy peasy, right?
Which brand of golf ball bounces the highest?
The brand of golf ball that bounces the highest can depend on various factors such as the core material, compression rating, and dimple design. Generally, golf balls with a higher compression rating tend to bounce higher due to their increased energy transfer upon impact. Brands known for producing high-performance golf balls with excellent bounce characteristics include Titleist, Callaway, and TaylorMade. Conducting a controlled experiment comparing different brands under identical conditions would provide the most accurate answer.
What is 0.54 rounded to the nearest whole number?
When rounding 0.54 to the nearest whole number, you look at the digit in the tenths place, which is 5. Since 5 is equal to or greater than 5, you would round up. Therefore, 0.54 rounded to the nearest whole number is 1.
A compound that has a specific number of water molecules bound to its atoms?
The term for a compound that has a specific number of water molecules bound to its atoms is a hydrate. In a hydrate, water molecules are typically attached to the compound through weak chemical bonds known as hydrogen bonds. The number of water molecules in a hydrate is represented by a numerical prefix in the compound's name, such as in CuSO4•5H2O, where there are five water molecules bound to each copper sulfate molecule.
What is an acrostic poem for force?
Fierce power ignites, Overcoming obstacles with might, Rapid like a charging horse, Strength in motion, unstoppable force.
Air pressure effect on soccer ball?
Air pressure in a soccer ball affects its bounce, flight, and overall performance. Proper inflation can improve ball control and accuracy, while underinflated or overinflated balls may lead to inconsistencies in play. It's important to maintain the recommended air pressure to optimize the ball's performance.
What are the freezing points of the elements on the periodic table?
Every metal has a different freezing point. Mercury has a freezing point well below zero, where Iron has a freezing point well above zero. It varies from substance to substance, and is again different from alloy to alloy.
Note: Freezing points are usually called melting points.
There are many forces being applied on the Shard as we speak including
Air Resistance if it moves in the wind
Gravity
Lateral forces from the wind.
Its own weight
Reaction force from the ground.
What are the principles of a store keeping?
The principles of storekeeping include proper inventory management, efficient organization of goods, accurate record-keeping, and effective stock control. Inventory management involves maintaining optimal stock levels to meet customer demand while minimizing excess inventory. Organizing goods in a logical and accessible manner helps facilitate quick retrieval and restocking. Accurate record-keeping involves documenting all transactions, including purchases, sales, and returns, to track stock movement and financial performance. Effective stock control involves implementing strategies to prevent stockouts and overstock situations, such as using forecasting techniques and setting reorder points.
Why can you smell things hot things but not smell cold things?
Its like water. Can you smell water? NO! So the cold things have ice on them, and the ice is made of water. You can't smell it. You can't smell boiling water either, so that argument doesn't hold.
Other things smell when its cold like petrol (gasoline).
Answer
When things are heated the molecules vibrate more rapidly, some molecules may gain enough energy the become a gas, but not all of them or your chocolate bar would evaporate! The gas molecules can diffuse through the air and up your nose where they can be sensed by chemical receptors. This makes cooking food that is very hot smell great.
If the object is cold the molecules will have less energy and fewer will become gaseous meaning fewer molecules reach your chemical receptors so the object will be harder to smell. Therefore you can't smell frozen foods very well at all.
Some molecules evaporate very easily such as petrol molecules, this means that you can smell them even though it is cold. Many molecules we just arn't very good at sensing, like water and oxygen, I guess we just don't have the correct chemical receptors. Imagine if we could smell how humid the day was for example, it would be a pain really and take a lot of brain power.
How do you use other sources of information to support the data?
In engineering you can use items around the workshop such as posters on info boards or their may already be drill and hole sizes for tap for example a 6.8mm drill bit for a M8 tap on a technical drawing or bend tolerences for the materials thickness.
Why do liver cells contain so many mitochondria?
Liver cells are the site of the most catabolic and anabolic reactions, with glycolysis, glycogenesis, gluconeogenesis occuring throughout the day. The majority of these processes are carried out by enzymes of the mitochondria and a higher number means larger reaction rate. So, the liver cells have many mitochondria to cope up with the reaction burden and also to provide energy for anabolic processes.
What causes rubber bands to rot?
Uncured natural rubber will begin to deteriorate within a few days, gradually breaking down into a wet crumbly mess. The process of perishing partly consists of proteins being broken down (much as milk proteins do) and also of the large rubber molecules breaking up as they oxidize in the air due to oxygen molecules attacking the double bonds.
Rubber that has been inadequately vulcanized also may perish, but more slowly. The process of perishing is encouraged by long exposure to sunlight, and especially to ultraviolet radiation.
What makes convection and conduction impossible?
Convection and conduction are not impossible, but rather limited in certain circumstances. For example, convection may be restricted in a vacuum where there is no medium to transfer heat through fluid motion, while conduction may be inefficient in materials with extremely low thermal conductivity. These limitations can impact the efficiency of heat transfer processes in specific environments.
How can you tell that the bat is not adapted to live in a polar climate?
Well, honey, bats are warm-blooded creatures, but they ain't built for the cold like a polar bear. They rely on their wings to fly and catch bugs, not to survive freezing temperatures. So if you see a bat shivering up in the Arctic, it's probably lost and looking for directions back to the tropics.
Why does water change from a solid to a liquid when heated?
Because the molecules vibrate and then bounce off off each other causeing them to spread apart.
