Answer:
1000cm³=1litre
1.5x10^6cm^3=1.5x10^6cm^3/1000litre=1.5×1000000/1000=1.5×1000=1500litres.
I am just answering so u can mark the other guy brainliest
I didnt see the answers for answer your question
Answer: D. They are made up of hard spheres that are in random motion.
Explanation:
A gas is a <u>state of aggregation of matter</u> in which, under certain conditions of temperature and pressure, <u>its molecules interact weakly with each other, without forming molecular bonds</u>, adopting the shape and volume of the container that contains them and tending to separate everything possible because of its <u>high concentration of kinetic energy</u>.
The molecules of a gas are practically <u>free</u> and have the ability to be distributed throughout the space in which they are contained because <u>the gravitational forces and attraction between them are practically negligible</u> compared to the speed at which they move. .
Therefore, gas molecules do not travel specific trajectories or vibrate in a stationary position, instead <u>they move quickly and randomly through the entire space of the container that contains them.</u>
