How do you tell how hot or cold something is?
use a thermometer.We can feel how hot or cold something is. However, sometimes things are just too hot or cold for us to feel safely. At other times we need to know exactly how hot or cold something is. When we need to measure temperature correctly we need to use an instrument called a thermometer. This measures temperature in degrees Celsius [sometimes called centigrade] or degrees Fahrenheit. There are different types of thermometers for different situations. A medical thermometer, for example, needs to be very accurate. It measures in fractions of degrees. When we are ill, even tiny changes in temperature are important. Some thermometers use a liquid that moves up a very fine glass tube. Most room thermometers, and outdoor thermometers are like this. The liquid is either mercury [ which is poisonous] or coloured alcohol. As liquids get warmer they expand [get bigger], and move up the tube. Water expands too, but not as much as alcohol and mercury. Thermometers that might be used by small children are not made of glass. They use a digital display which lights up the temperature. Inside the displays are chemicals that change colour according to the temperature.
Mercury thermometer analog or digital device?
The traditional mercury thermometer has the mercury in a narrow glass tube with the readings/markings etched into the glass so it is neither analogue nor digital. I thought it was analogue.

Are bamboo floors as durable as traditional wood floors?
Bamboo flooring is a viable eco-friendly option to traditional wood floors. It is just as durable, and very attractive. Indeed they are as durable if not more so. Bamboo has great tensile strength while it retains the ability to give and expand under pressure and temp changes. The only woods that might be better are ash and hickory, but you will have to pay big time for those.
