The temperature of two bodies measured by a thermometer are t_1=20^@C pm 0.5^@C and t_2=50^@C pm 0.5^@C . Calculate the temperature difference and error there in .

A 0.50 kg ice cube at -10^(@)C is placed in 3.0 kg of coffce at 20^(@)C . What will be the final temperature of mixture? Assume that specifec heat of tea is same as that of water.

2kg ice at -20"^(@)C is mixed with 5kg water at 20"^(@)C . Then final amount of water in the mixture will be: [specific heat of ice =0.5 cal//gm "^(@)C , Specific heat of water =1 cal//gm"^(@)C , Latent heat of fusion of ice = 80 cal//gm]
