Exam 12: Temperature and Heat

A 0.040-kg ice cube at 0 °C is placed in an insulated box that contains 0.0075 kg of steam at 100 °C.What is the equilibrium temperature reached by this closed system? Note: Assume that all of the ice melts.

What is the latent heat of vaporization of this material?

A metal rod 40.0000-cm long at 55.0 °C is heated to 85.0 °C.The length of the rod is then measured to be 40.0264 cm.What is the coefficient of linear expansion of the metal?

Using the data in the table, determine how many calories are needed to change 100 g of solid X at 10 °C to a vapor at 210 °C.

In an insulated container, 0.50 kg of steam, initially at 140 °C, is mixed with 2.0 kg of ice, initially at -20.0 °C.What is the final temperature inside the container if heat exchanges with the container are ignored?

A tanker ship is filled with 2.25 × 10⁵ m³ of gasoline at a refinery in southern Texas when the temperature is 17.2 °C.When the ship arrives in New York City, the temperature is 1.3 °C.If the coefficient of volumetric expansion for gasoline is 9.50 × 10^-4/C°, how much has the volume of the gasoline decreased when it is unloaded in New York?
