Question

If 10 g ice at 0°C is mixed with 10 g water at 20°C,
the final temperature will be :-
(1)50°C (2) 10°C (3)0°C (4) 15°C​

Answer 1

Answer:

final temperature is 0°

Explanation:

to dissolve all ice we need latent heat= mL =10×80

=800

but water can give = ms∆t amount if energy =10×20×1

=200

so all ice cannot dissolve and final temperature is 0°
