Because of the gravity on earth, and the momentum they get from spinning around the planet.
That's Newton's 1st law of motion, sometimes called the inertia law.
Answer:V₁=300ml
T₁=27°C
V₂=?
T₂= -3°C
as we know
V₁T₁=V₂T₂
By putting values in formula
300ml×27°C=V₂×(-3°C)
300ml×27°C/-3°C=V₂
8100ml/-3=V₂
-2700ml=V₂
or V₂= -2700ml
Answer:
The box contains a finite number of chocolates making it a closed system since this number does not change.
After taking the box and opening it to eat some chocolates it becomes an open system that can exchange chocolates with the medium
Explanation:
In thermodynamics an isolated system is a system in which no heat is exchanged with the medium, a closed system is a system where no particular one is exchanged with the surrounding medium.
In this case, the box can exchange heat since the cardboard walls are not insulating, so it is not an insulated system.
The box contains a finite number of chocolates making it a closed system since this number does not change.
After taking the box and opening it to eat some chocolates it becomes an open system that can exchange chocolates with the medium
