Hi! I am having problems solving this question:
0.01kg of melting ice is put into a vacuum flask containing
water with initial temperature 50.0'c.
The mixture is stirred well and the ice melts completely.
The final temperature of the water becomes 45.5'c. Assume that
no energy is lost to the surrounding, what is the mass of the water
originally in the flask?
(Specific heat capacity of water = 4200J/(kgK), specific latent
heat of fusion of ice = 3.34x10^5)
ANS: 0.28kg
Anyone here knows how to solve this?
heat loss by water= heat gain by ice
= A
A = M x 4200 x (50-45.5)
= 0.28kg
or thats how it should be done.
