Select the correct answer. In an Isolated system, two copper bars at different temperatures transfer energy until both are at the same temperature. How would the
transfer of energy be different if the bars were in an open system?
O A Energy transfer would occur only between the copper bars.
OB. Energy transfer would occur between the copper bars and the surroundings.
Ос.
No energy transfer would occur between the copper bars or the surroundings.
D.
Energy transfer would occur only with the surroundings.

Significant figures are digits read directly from the measuring instrument plus one more digit, which is __ by the observer.

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.
