Answer:
The motion of the molecules slow down
Explanation:
In heating process, increase in the temperature increases the motion of the molecules and hence it gains the kinetic energy and moves.
While in the cooling process, decrease in temperature reduces the speed or motion of the molecules and that's why during cooling kinetic energy of the molecules falls down.

Answer:
#_time = 7.5 10⁴ s
Explanation:
In order for the astronaut to be younger than the people on earth, it follows that the speed of light has a constant speed in vacuum (c = 3 108 m / s), therefore with the expressions of special relativity we have.
t =
where t_p is the person's own time in an immobile reference frame,

let's calculate
we assume that the speed of the space station is constant
t_ = 0.99998666657 s
therefore the time change is
Δt = t - t_p
Δt = 1 - 0.9998666657
Δt = 1.3333 10⁻⁵ s
this is the delay in each second, therefore we can use a direct rule of proportions. If Δt was delayed every second, how much second (#_time) is needed for a total delay of Δt = 1 s
#_time = 1 / Δt
#_time =
#_time = 7.5 10⁴ s
Answer:
geothermal energy
Explanation:
the energy is obtained from the heat within the surface of earth
