Posted by Mikky on Sunday, October 10, 2010 at 6:30pm.

a bunsen burner flame takes 8 minutes to raise 250g of water from 20 degrees to 100 degrees celcius, when the water is in a beaker of mass 100g (c=0.67J/g degrees celcuius). How long will i take to raise the temperature of 200g of glycerin (c=2.43J/g degrees celcius) contained in the same beaker from 20 to 80 degrees celcius?
