Question

Explain water clock and sand clock​

Answer 1

• A water clock, also known as a clepsydra, is an ancient timekeeping device that uses the flow of water to measure the passage of time. It consists of a container with a small hole at the bottom, which allows water to slowly leak out. The time it takes for the water to empty out of the container is measured and used to track the passage of time.

• Sand clocks, also known as hourglasses, are another type of ancient timekeeping device that use the flow of sand to measure the passage of time. They consist of two glass bulbs connected by a narrow neck, with one bulb filled with sand. As the sand flows from the top bulb to the bottom, it measures the passing of time. Sand clocks were often used as a portable timekeeping device, as they were relatively small and easy to carry.

water clock: an instrument used to measure time by regulating water flow.

sand clock: an instrument used to measure time by regulating sand.
