Water can cast shadows because it is a semi-transparent substance that can absorb and reflect light. When light hits the surface of the water, some of it is absorbed while the rest is reflected. The absorbed light creates shadows in the areas where the light cannot pass through the water, resulting in the formation of shadows on the bottom or sides of the body of water. The depth and clarity of the water, as well as the angle of the light source, can affect the visibility and intensity of the shadows cast by water. **

To determine if the hot water boiler is too hot, you should check the temperature setting on the boiler. The recommended temperature for hot water in a boiler is typically between 120-140 degrees Fahrenheit. If the temperature is set higher than this range, it could be considered too hot and may pose a risk of scalding. Additionally, if the hot water coming from the boiler feels uncomfortably hot to the touch, it may also be too hot and should be adjusted to a safer temperature. **
