A theory is subject to modification and even rejection if there is overwhelming evidence […]
Which metal is used in clinical thermometer?
Which metal is used in clinical thermometer? Mercury is the only one in liquid state at room temperature. It’s used in thermometers because it has high coefficient of expansion. Hence, the slightest change in temperature is notable when it’s used in a thermometer. What are five sites for measuring body temperature? The most common ones […]
Does rubber shrink when heated?
Does rubber shrink when heated? Polymers like rubber shrink on heating as their molecular chains curl up, and water shrinks when warmed from its freezing point to around 4°C. After that, though, it behaves normally, and expands on warming. In contrast, so-called negative thermal expansion (NTE) materials never behave themselves. Why does rubber shrink when […]
