Answer:
The atoms of the system with higher temperature will gain the heat energy and the vibration of these atoms will increase. The atoms or molecules on the system with lower temperature have lower temperature and are not vibrating. ... So, we can say that heat always flows from higher temperature to a lower temperature.
The reason is that a closed system has nothing going in or out and water retains energy very well also water it polar so it is attracted to itself. It doesnt like contact with other things.
So it's likely to be C
The discovery of Uranus, Neptune, most asteroids, the moons of
any planet other than Earth, Pluto, and all the other dwarf planets,
required the invention and use of telescopes. Those objects are all
too dim to be seen with a bare naked human eye.
Saturn is bright and plainly visible with your eyes, if you know when
and where to look, and what you're looking at.
If Earth had no atmosphere, a falling object would never reach terminal velocity. Terminal velocity is created by friction between a thing and the atmosphere. If there is no friction between objects, the object will accelerate forever.
Answer:
=30.22°C
Explanation:
The enthalpy change made the water to cool.
Enthalpy change = MC∅ where M is the mass of the water, C is the specific heat capacity of water and ∅ the temperature change.
ΔH=MC∅
∅=ΔH/MC
=(6.3×10⁴J)/(0.5kg×4186J/(kg°C))
=30.1
Final temperature = 35.00°C-30.1°C
=4.9°C
