Science help!

I have got the results of my sciene experiment and my hypothesis was correct that

the lower the volume of water the faster it cools

i have to explain why this happens and write it in my conclusion can n e one explain to me why the beaker with 20ml of hot water cools before a beaker with 100ml of hot water please help me out!!!!

thanks

That doesn't sound right, I'd expect a larger beaker of water with the same overall heat as the smaller one to cool faster, because there's a larger surface area in contact with the air and the glass so heat can be lost faster.

True, but it is all about the surface area to volume ratio. And the amount of ehat retained. Like a polar bear and shrew anolagy

The ratio (Surface area of water : Volume of water) is greater when there is 20ml of water than when there is 100ml.

The greater the surface area, the more quickly heat is lost. The greater the volume, the more heat there is for a given temperature.
