1. The document discusses laws of thermodynamics and specific heat capacity. It states the first, second, and third laws of thermodynamics. 2. It then explains that specific heat capacity is the amount of heat required to change the temperature of a substance. Water has a higher specific heat capacity than sand, so it takes longer to warm up or cool down. 3. The document notes that water's high specific heat capacity affects Earth's climate by moderating temperatures and influencing ocean currents.
