Question

A=14 B=39

Let A be the sum of the last three digits and let B be the last two digits of your 8-digit student ID. Example: for 20245347, A 14 and B-47 A g ice cube at-15.0 is placed in g of water at 48.0°C. Find the final temperature of the system when equilibrium is reached. Ignore the heat capacity of the container and assume this is in a calorimeter, ie. the system is thermally insulated from the surroundings. Give your answer in oc with 3 significant figures. Specific heat of ice: 2.090 J/g K Specific heat of water: 4.186 J/g K Latent heat of fusion for water: 333 J/g

Explanation / Answer

Mass of ice=24g

Mass of water=164 g

Let final temp is T

Heat lost=heat gained

24*2.09*15 +24*333+24*4.186*T=164*4.186*(48-T)

We got

T=30.7 C
