Physics Trick Exposed: Water Saves Cup from Melting
The trick in the video where a plastic cup doesn't melt when there's water inside is explained by the concept of specific heat capacity.
Specific heat capacity is a property of a substance that indicates how much heat energy is needed to raise the temperature of a given amount of that substance by 1 degree Celsius. Water has an exceptionally high specific heat capacity, about 4184 joules per kilogram per degree Celsius. This means it requires a significant amount of energy to increase the temperature of water, making it an efficient heat storage medium.
Water's high specific heat capacity has important implications for both natural environments and human activities. It helps regulate temperature in oceans, lakes, and living organisms, contributing to climate moderation and stability in coastal regions. Additionally, water's ability to absorb and store large amounts of heat plays a crucial role in weather patterns.
