Lil;y wanted to find out how mugs of different materials and different sizes affect how fast water cools down. She poured hot water into four mugs. She recorded the temperatures of the water before and after a 30 minute interval.
Can her experiment work? What are the mistakes of her experiment?

Metal. It's the most conductive material. yes her experiment can work. the mistake is that she is not recording the temperatures often enough AND she must ensure that the water in each mug STARTS at the same temperature. Also, they should all be in exactly the same environment. The mugs must be exactly the same size and shape as well, containing perfectly equal amounts of liquid.

metal is the fastest. plastic one is the slowest.
