Question

You are handed a well insulated container holding about 100ml of water at a temp between 75 deg C and 100 deg C. you are given a thermometer with a maxmimum temp of 50 deg C. create an experiment to determine the temp of the water.

i am really confused on how to start this problem. we did an experiment with calorimeters such as specific heat of a metal,enthalpy of dissolving a salt in water, entahlpy of a neutralization reaction and heat fusion of water, could i alter one of these experiments to make this one work. is there an equation for this problem that i could link to one of these experiments

Answer 1

What happens if you add 100 ml water (ice water, no ice) at zero C, then measure the final temperature?

Answer 2

your and

Answer 3

the ice water would lower the original temp, but im still confused on how i would use that to calculate the original temp of the water

Answer 4

heat gained by ice water (you know both Tfinal and Tinitial) + heat lost by warmer water (Tfinal which you know and Tinitial which you don't know) = 0. What's the only unknown in the equation?

Answer 5

the only unknown would be the intial temp, for the heat gained by ice water would the intial be 0 deg and final would be waterever the fianl temp of the mixture of warm and cold water

Answer 6

It's tough reading with no caps and no periods and/or question marks. Yes, ice water Ti is 0 and Tf final T of solution. Ti for warm water is unknown. Tf is same for ice water and warm water.
