Why does a tin can transmit sound better than air?
Because a tin can is a solid the atoms are more densly packed therfore the sound wave travels faster through the atoms in a tin can as opposed to air where the atoms are spaced further Apart.
Why does a sealed empty tin can collapse when the air inside the can is pumped out?
Because the air pressure is 15 lb per square inch, so when you take the air out, there is no pressure inside, so the pressure outside the can crushes it.
Does tin foil attract heat?
Tin foil is generally made of aluminum and can attract/transfer heat. Aluminium is widely used as cooling in computer systems, which spreads the heat all over the heatsink so the air can cool the aluminum down.
Does mass alone determine wheter an object will float or sink?
No. The key to whether an object floats or sinks is the average density, i.e., mass divided by volume. Also, whether an object will float or not also strictly depends on the surface volume. A piece of tin foil shaped into a boat will float and the same mass of tin foil shaped into a crumpled up ball will not float.
How long does 70 gallons of heating oil last?
Provided it is in a cloased tin it will last for many years.
What is the atomic mass for tin?
There are various isotopes of tin with different atomic mass. The average atomic mass of tin is 118.71 amu. The symbol commonly used for tin is Sn.
Why do tin cans get crushed if cooled after heated and closing is mouth?
Assuming the can can be sealed. When the can is heated the air inside it expands. If the can is then sealed and allowed to cool the air inside contracts which causes the pressure inside to drop. Because the outside air pressure is now greater it crushes the can.
Why did the pin wheel spin when a lighted candle was placed below the open end of the tin?
Heat. As the air expands (as it's heated), it rises and causes air to flow upward.
What happens if coke tin is filled with water and heated on hot plate then placed in cold water?
it'll get crushed due to air pressure
What is the atomic mass of tin?
The atomic mass of tin is approximately 118.71 atomic mass units.
Calculate the Mass of Sn in the tin oxide product?
Calculate the mass of Oxygen in the tin oxide
How many atoms of tin are in 119 g of tin?
The mass of tin is slightly more than the relative atomic mass of tin (118.71). There will be 6.037*10^23 atoms.
What is the molar mass of tin, which has an atomic mass of 118.7 amu?
The molar mass of tin is 118.7amu, 118.7 grams per mole
What is the mass number of an atom of tin that has 70 neutrons?
The atomic mass of Yb is 173.04 AMU.
What is the mass number of the tin?
The atomic mass number of tin is 118.71 u. Its symbol is Sn and its atomic number is 50. Tin is a malleable metal often used for cans.
How many moles of tin metal will be produced when 0.74 moles of tin IV oxide is heated?
The formula for tin (IV) oxide is SnO2. This formula shows that each formula unit contains exactly one tin atom. Therefore, if 0.74 mole of tin (IV) oxide is heated sufficiently to cause complete disproportionation of the compound to its constituent elements, 0.74 moles of tin metal will be produced.
What is the molar mass of tin?
Tin (Sn), atomic #50 has a molar mass of 118.71 g/mol
