C- Electron
A-Nucleus
B-Neutron
D-Protron
Answer:
Explanation:
Given that,
The volume of a sample of gas measured at 27 °C is 10.0 dm.
We need to find the temperature when the volume is reduced to 9.0 dm at the same pressure.
According Charles law,
Where, T₂ is new temperature
So, the new temperature is 
.
Answer:
B
Explanation:
It's B because the first trial of an experiment may not always be right so you want to run multiple trials
Answer:
Conservative Properties of Seawater
Explanation:
The Conservative properties of seawater refer to those properties that cannot be altered due to the occurrence of physical, chemical and biological processes, over the large oceanic bodies. This typically comprises properties such as the temperature and also there is a high concentration of both sodium and chloride ions, which increases the salinity of the oceans.
These conservative properties occur in almost a fixed amount, or it most probably changes at a very slower rate through time. They can be considered to have a long residence time.
The average distance a gas particle travels between collisions (with the wall or another particle is called the mean free path.
According to the kinetic theory of gases, the particles of a gas (atoms or molecules) have the highest kinetic energy and travel at high speeds. At standard temperature and pressure, a gas particle can reach speeds of about 470m/s.
Despite the high speeds gas particles travel, it still takes a while for the fragrance of an opened perfume to diffuse to the other end of the room. This is because when moving, the molecules do not have a free path. They constantly collide with other particles and the walls of the container and change direction randomly. The average distance a single particle can travel without colliding with other particles, or the wall of the container is called the mean free path.
