“How do meat thermometers work?”
Meat thermometers are used every day to measure the temperature of meats. However, how exactly do they work? Well, let’s use our engineering mindset to find out. If we were to deconstruct one of these machines, then we would find out that inside the thermometer are two strips of metal with different heat coefficients. Upon the application of heat, both of these will expand at different rates, inducing twisting and therefore changing the dial at a constant rate!
