Answer:
Heating a substance increases the speed at which molecules move.
Explanation:
A beachside all objects have thermal energy but thermal energy is the sum of the energy of all the particles so the more particles the more energy.
by radiation from the Earth's surface
Answer:
D. The sun has less gravitational pull on Pluto because it is farther away.
There are two subshells that are s and p, which are present in the second energy level.
The energy level can be defined as the fixed distances from the nucleus of an atom where electrons may be found. Each energy level is divided into some Subshells. These subshells are known as s-subshell, p-subshell, d-subshell, and f-subshell. This subshell contains some orbitals, these orbitals are the place where there is the maximum probability of getting the electrons. In one orbital, a maximum of two electrons can be present.
Hence, there are two subshells in the second energy level.
