You are holding four identical balloons each containing 10.0g of a different gas. The balloon containing which gas is the larges
Vaselesa [24]

Answer:

Hydrogen, H_2

Explanation:

mass of each gas is 10.0 g

number of mole =  mass/ molar mass

number of moles is directly proportional to volume at constant temp and pressure

this implies that the  volume is inversely proportional to molar mass. And Among all the gases in periodic table the molar mass of Hydrogen is the least.

molar mass of H2=2 g/mol

Since, H2 has minimum molar mass then for the same mass of the gases Hydrogen will have maximum volume.

Select ALL correct answers. The contact force is caused by: A. Atoms randomly crashing into each other B. The charged particles
Inessa [10]

Answer:

A. Atoms randomly crashing into each other

E. The force of one object pushing against the force of another object.

Explanation:

Forces can be classified into two categories based upon the the mode of transfer or application:

1. Contact forces

2. Non-contact forces

Contact forces are the ones which require the physical contact of the matter to get transferred and tend to create the affect. Whereas non-contact forces have the field property which transfers the affect of force from one point to another without any physical contact of the matter or the medium.

  • Atoms crashing onto each other have some mass and velocity which upon collision impacts the other atoms exerts a contact force.
  • The interaction between the charged particles due to their charges is always due to the electric field be it electron or proton, be it within an atom or out of an atom.
  • The force between any two objects pushing or pulling each other is also possible only due to contact.
