beks73 [17]3 years ago
8 0

Answer:

Matter can be broken down into two categories: pure substances and mixtures. Pure substances are further broken down into elements and compounds. Mixtures are physically combined structures that can be separated into their original components. A chemical substance is composed of one type of atom or molecule.

Hope this help's :)

<span>8.21 L of C3H8(g) Lets take c as the molar volume at that temperature.
    c L <><> 5c L

A peregrine falcon can travel 537,600 furlong/fortnight. A race car travels 212ft/s. A spider can jump with a maximum velocity o
o-na [289]
Convert everything to one base unit (let's do ft/s in this case)
There are 660 ft in a furlong and 2 weeks or 1209600 seconds in a fortnight
Multiply 537,600furlong and 660 ft/furlong and divide by 1209600 to get 293.333ft/s

The race car is already in ft/s

There are 30.48 cm in 1 foot and 3600 seconds in 1 hour.  Multiply 9,000,000 by 1/30.48 and 1/3600 to get 82.02ft/s

THe peregrine falcon is the fastest

When a liquid is cooled, the kinetic energy if the particles A. Decrease B. Increases C. Remains the same. The force of attracti
scoray [572]

Answer:

  • (A.) Kinetic energy decreases
  • (B.) Force of attraction increases
  • (C.) Space between particles remains the same

Explanation:

Kinetic energy is the energy in motion. Cooling if liquid would cause decreased temperature and hence slow down the oscillation of the particles.

Likewise, increased heat reduces the force of attraction between said particles, which allowed for their free movement. So the cooling would have opposite effect.

Finally, the space between the particles would remain the same as it was originally, as their force of attraction is increased in the cooling process, they would take the form they are held in.

I hope this was helpful and concise?
