If you place 0 ice into 0 water in an insulated container, what will the net result be? Will there be less ice and more liquid water, or more ice and less liquid water, or will the amounts stay the same?
An underground gasoline tank can hold 1.00 103 gallons of gasoline at 52.0F. If the tank is being filled on a day when the outdoor temperature (and the gasoline in a tanker truck) is 95.0F, how many gallons from the truck can be poured into the tank? Assume the temperature of the gasoline quickly cools from 95.0F to 52.0F upon entering the tank.

A firewalker runs across a bed of hot coals without sustaining burns. Calculate the heat transferred by conduction into the sole of one foot of a firewalker given that the bottom of the foot is a 3.00-mm-thick callus with a conductivity at the low end of the range for wood and its density is 300 kg/m3. The area of contact is 25.0 cm2 the temperature of the coals is 700 , and the time in contact is 1.00 s. Ignore the evaporative cooling of sweat.
A sample of neon gas (Ne, molar mass M=20.2 g/mol) at a temperature of 13.0 is put into a steel container of mass 47.2 g that's at a temperature of 40.0 . The final temperature is 28.0 . (No heat is exchanged with the surroundings, and you can neglect any change in the volume of the container.) What is the mass of the sample of neon?
A 1.00-km steel railroad rail is fastened securely at both ends when the temperature is 20.0C. As the temperature increases, the rail buckles, taking the shape of an arc of a vertical circle. Find the height h of the center of the rail when the temperature is 25.0C. (You will need to solve a transcendental equation.)
Hot or cold objects are observed to cool down or warm up, respectively, to reachthe temperature of the environment. If the temperature difference ∆T between the object and its neighborhood(∆T = Tobjeto - Tvizinha¸ca) is not large, the cooling or heating rate of the object will beapproximately proportional to the temperature difference, i.e,d ∆T/dt = -A (∆T) ,where A is a positive constant. This is Newton's law of cooling. a. Why is there a minus sign in the equation?b. What factors does A depend on and what are its dimensions?c.

Occasionally, huge icebergs are found floating on the ocean’s currents. Suppose one such iceberg has a regular volume and is 120 km long, 35 km wide, and 230 m thick. (i) How much heat would be required to melt this iceberg (assumed to be at 0°C) into liquid water at 0°C? (The density of ice is 917 kg/m3. The latent heat of fusion for ice is 33.5 x 104 J/kg.) (ii) Assume the average annual energy consumption by a developed country in the past years was 9.3 x 1019 J. If this energy were delivered to the iceberg every year, how many years would it take before the ice is completely melted? (iii) What will be the outcome(s) and possible implication(s) in (ii) if the time rate of the changes in average annual energy consumption is a positive number?
