Answer:
Explanation:
Kinetic molecular theory of gasses stated that,
1) Gases consist of large number of smaller particles which are distance apart from each others.
2) The gas molecules collide with each other and also with wall of container and this collision is elastic.
3) Gas molecules are in continuous random motion and posses kinetic energy.
4) The forces of attraction between gas molecules are very small and considered negligible.
5) The temperature of gas is directly proportional to average kinetic energy of gas molecules.
B). 2 Hours
Explanation if the older brother can run 6 MPH and it’s takes him a hour and twenty minutes you automatically can say it’s at least 6 miles then you have to see how many he can run in 20 minutes which is roughly 2 miles so that would mean he run for 8 miles if the younger brother can run 4 MPH then you just have to add that by 2 too see how long it will take to run 8
Answer:
it can help heat or cool a room.
Explanation:
I think this is right...
Answer is: 1) nuclear, and energy is released.
Missing question:
1) nuclear, and energy is released.
2) nuclear, and energy is absorbed.
3) chemical, and energy is released.
4) chemical, and energy is absorbed.
Missing reaction: n° + 92/235U → 52/137Te + 40/97Zr + 2n°.
This is nuclear reaction, because nucleus of an atom (in thus example uranium-235) and a subatomic particle neutron from outside the atom collide and produce two nuclides (tellurium-137 and zirconium-97) that are different from the nuclide that began the process and two netrons are released.
Answer:
Gold
Explanation:
Gold has a density of 19.3 while the rest have all densities of below 5
