To treat a burn on his hand, a person decides to place an ice cube on the burned skin. The mass of the ice cube is 11.4 g, and its initial temperature is − 11.1 ∘ C. The water resulting from the melted ice reaches the temperature of his skin, 28.0 ∘ C. How much heat is absorbed by the ice cube and resulting water? Assume that all of the water remains in the hand.

You drop an ice cube into an insulated container full of water and wait for the ice cube to completely melt. The ice cube initially has a mass of 80.0 g and a temperature of 0°C. The water (before the ice cube is added) has a mass of 660 g and an initial temperature of 20.0°C. What is the final temperature (in °C) of the mixture? (Assume no energy is lost to the walls of the container, or to the...

A person holds two bricks together in one hand, pinching them as indicated by the arrows in the -figure to the left. As can be seen, the bricks have a tendency to swing apart at the bottom, contacting only at their top edges. We want to analyze the system to better understand its behavior and stability conditions (i.e. the bricks are not swinging around or falling out of the person's hand). This is done by analyzing a free body diagram...
