Answer to Question #285457 in Physics for haasggdfnsd

Question

 If 10.0 g of ice at 0°C were added to 10 g of water at 20°C, what is the resulting temperature of the mixture?

Answer 1

1) Determine heat to melt the entire ice:

$Q_1=m_i\lambda=3340\text{ J}.$

2) Determine heat to cool water to 0°C:

$Q_2=cm_w(20-0)=840\text{ J}.$

So, the final temperature of the mixture is 0°C.
