Kinetic energy can be expressed in heat, motion, light, and sound.
The correct option is 2.
Gases has some properties which are specific to them, one of these properties is that, gases usually take the shape and the volume of any container in which they are confined. This means that, when a gas is sealed up in a container, the gas will fill up all the space inside the container.
Thus, gases have no definite shape and no definite volume, they take the shape and the volume of their containers. Also, the forces of attraction between gas molecules are very weak, that is why their particles are far apart.<span />

There are 5 significant figures in your measurement.
Significant digits are the digits following the two zeros at the start of your measurement.
- zeros in front of measurement don’t count as significant figures.
- however zeroes following real numbers count as significant digits.
23040 are significant.
<span>One
mole of carbon weighs 12 grams and one mole of hydrogen weighs 1 gram.
Therefore, one mole of CH2 weighs 12 + 1 + 1 = 14 grams.
56 divided by 14 = 4
Therefore, you need 4 "moles" of CH2 to equal 56 grams of the unknown
substance. To get the equivalent of 4 "moles" of CH2 you need one mole
of C4H8.
Hope this helps :)
