Why can blonde human hair be used to measure humidity using a mechanical hygrometer?

Because a human hair is used as a type of 'spring' in the device, which expands or contracts according to the moisture present and this moves the indicator needle, thus providing a measurement of the atmospheric humidity.


Why would a hot ball bounce higher than a cold ball?

A hot ball would bounce higher than a cold ball because it is more flexible and compresses more than a cold ball on impact. This means that at the moment the ball is stationary, before bouncing up, the ball has more energy stored - much like a spring - allowing the ball to propell itself upwards with a higher force. The hot ball will reach a point, however, where it will either become sticky or lose its rigidity so much that it won't return to normal after impact. Beyond this point the ball will bounce less and eventually not at all. So a bit of rigidity is important for a ball to bounce, but too much is not good! A hot ball bounces higher than a cold ball because all the rubber and molecules are frozen and wont work well Also, to improve,it's because hot water has more pressure in it. If the ball has more pressure in it, the surface of the ball becomes really hard and super bouncy.
