Given the law of conservation of energy, what happens when a 200°c iron bar is placed in thermal contact with a 30'c block of wood?
o a
energy leaves the iron bar and enters the wood until the temperatures are equal
ob.
oc.
energy leaves the wood and enters the iron bar until the temperatures are equal.
all the energy from the iron bar is transferred to the wood.
od.
all the energy from the wood is transferred to the iron bar.

Problem page combustion of hydrocarbons such as pentane ( c5 h12 ) produces carbon dioxide, a "greenhouse gas." greenhouse gases in the earth's atmosphere can trap the sun's heat, raising the average temperature of the earth. for this reason there has been a great deal of international discussion about whether to regulate the production of carbon dioxide.(a) write a balanced chemical equation, including physical state symbols, for the combustion of liquid pentane into gaseous carbon dioxide and gaseous water. (b) suppose 0.350 kg of pentane are burned in air at a pressure of exactly 1 atm and a temperature of 20.0 degree c. calculate the volume of carbon dioxide gas that is produced.be sure your answer has the correct number of significant digits.
