What is the internal energy of an ideal gas at room tempature?

I live in a 1911 Craftsman in Seattle. The heating situation is... pretty weird. (See the "more inside".) My 42-year-old oil furnace still works like a champ, but the oil company folks say they won't service it any more and it has to be replaced...

My landlords are obliged by law to check gas fires by law for carbon monoxide leakage. The last time this was done the contractor found it unsafe and disconnected it. I asked the property managing agent for a replacement. She said they would only replace...

Tell me!!

What BEST explains the difference in their states of matter at room temperature? a) The temperature remains constant even though energy is added during a phase change from liquid to gas. b) Compounds with decreasing molecular weights tend to have lower...

A family member strongly believes that closing the heat registers of rooms/areas that aren't being used is the best way to save on gas bills in the winter. I can almost agree if the room that isn't used can be closed. But what about common areas like...

a) move faster b) strike the walls of the container with less force c) decrease in average kinetic energy d) decrease in volume
