Question

An experiment was set up to investigate the cooling of water in two flasks. One flasks was painted shiny white. The other was painted Matt black. The starting temperature of the hot water poured into both flasks was 80 degrees. Explain what other quantity had to be kept the same in both flasks to make the experiment fair.

Answer 1

add add more hot water in the flask painted shiny white while less of it in the one painted Matt black

Step-by-step explanation:

Let's name the flasks A and B respectively

flask A due to the nature of its exterior will tend to reflect heat from the environment thus will need more hot water while flask B since it painted in Matt black the heat will be absorbed from the environment thus will require less hot water
