Concept explainers

Conduction and Convection

When energy travels from one object to another it is said to have undergone heat transfer. Heat transfer is nothing but the transfer of thermal energy or internal energy from one thing to another, like e.g., when a vessel with water, kept on top of a burner, heats up because of the flame underneath it.

43.0 g of 40Ar gas are sealed in a container at an initial pressure of 1.50 atm and an initial volume of 0.0500 m3 (state 1). The gas is then made to expand very, very quickly until its volume doubles (state 2). Then it is compressed very, very slowly back to its initial volume (state 3). Show the two processes on a pV diagram, and fill out the table below. p1 = p2 = p3 = V1 = V2 = V3 = T1 = T2 = T3 =

Suppose we have a piece of a candy bar that has an initial mass of 28g. If we ignite the piece of candy bar (literally burn it), and it increases the temperature of 285.23g of water from 18.95°C to 77.43°C, how many calories per gram of energy did the candy bar provide if the final mass of the marshmallow is 4.45? Note: 1.00 cal = 4.184 J. Give your answer in units of cal/g.

There is an 500g container made out of aluminum holding 300g of water. The Water and Aluminum have reached thermal equilibrium at 40 degrees Celsius. A 200g block of iron at a temperature of 0 degrees Celsius is later dropped into the water. Using the specific heat for water=4180J/kg/C. The specific heat for aluminum is 900 J/kg/C. The specific heat for iron is 450 J/kg/C. The final temperature of the three materials will be degrees celsius. The thermal energy of the water changes by Joules.

NOTE: Complete solution and show the derivation/cancellation of units. A steel flask of 0.04 m capacity is used to store Nitrogen at 120 bar and 20°C. The flask is protected against excessive pressure by a fusible plug which will melt and allow the gas to escape if the temperature is too high. A. How many kilogram of Nitrogen will the flask hold at the design conditions? B. At what temperature in °C must fusible plug melt in order to limit the pressure of flask to a maximum of 150 bar?
N = 0 An insulated tank of volume 10+(10+N)/25 m and with a valve was filled with perfect tri- atomic gas at pressure 10 bar, where N is equal to the last two digitals in your student's ID number. Initially the valve was closed. A paddle wheel was mounted inside the tank and was run by 20 kW engine. The paddle wheel was turn on and at the same time the exit valve was opened. The gas temperature was constant though the whole process (due to very slow flow) and equal to 300 K. Calculate the time needed to decrease the pressure in the tank to 5 bar.
