A scientist performed an experiment using a wax candle and a large airtight glass container filled with oxygen. Nothing could get into or out of the glass container during the experiment. The scientist measured the mass of the unlit candle and the container to be 956 grams at the beginning of the experiment. Then, she lit the candle. After a short time, the candle stopped burning, and it appeared slightly smaller. What will the mass of the candle and the container be now that the experiment is over?
A.
The mass will be exactly 956 grams because mass is always conserved in closed systems.
B.
The mass will be less than 956 grams because smoke weighs less than wax.
C.
The mass will be less than 956 grams because burning the candle turns it into energy.
D.
The mass will be more than 956 grams because burning the candle creates smoke.

"where ha ye come fra? the swamp, that awfu' swamp. what were ye doin' there? " etc. "mony a puir body has been lost in that muckle, cauld, dreary bog and never been found." when i told her i had entered it in search of plants and had been in it all day, she wondered how plants could draw me to these awful places, and said, "it's god's mercy ye ever got out." examine the details muir includes in this paragraph. which statement accurately explains how muir's response to nature compares to the log house owner's response? he is enthusiastic and in awe while she is doubtful and fearful. muir cautiously admires whereas the lady shows religious dedication. the lady is more interested in the bog while muir is fascinated by plants. they both admire nature—its intense dangers and its true treasures.
