Answer:
High and low tides are caused by the Moon. The Moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the Moon and the side farthest from the Moon. These bulges of water are high tides.
Explanation:
Thermal-energy flow between objects is conserved and always flows from the warmer object to the cooler object.
Here 'conserved' means that the amount of thermal energy lost of by one body is exactly equal to the amount of thermal energy gained by another body, which is the statement of the first law.
According to second law, we do not see objects warming up on their own. For example, if we have a cup of coffee left to itself, we would always see that it cools down. Here, thermal energy is being transferred from warmer object (coffee) to cooler objects (the air in the room).
