Make Ice Cubes

Last question:

Is it really true that no two snowflakes are exactly alike?

Answer:

Yes. Most snowflakes look alike as you watch them fall from the sky. What you see under a microscope is something entirely different. The size, shape, and texture of snowflakes are determined by a wide variety of factors including temperature, humidity, and other atmospheric conditions at the time it is formed.

At a molecular level, the number of possible variations is huge. The possibility that any two snowflakes will be exactly alike, even when formed under similar conditions, is virtually zero. I suppose you could try and find two snowflakes that are alike, but they would probably melt before you could validate your finding!

Last Question:

Can burning wood in a fireplace can make the inside of a house colder?

Answer:

Yes. A fire in the fireplace may evoke feelings of warmth and coziness, but in actuality it can be an inefficient way to heat your home. The design of most traditional masonry fireplaces creates a draft that pulls air out of the room to fuel the fire and causes the majority of the heat generated by the fire to go up the chimney. This, in turn, can draw cold air in through other leaks in your home, making it colder rather than warmer.

I personally do use a fireplace to heat my home in the winter. The fireplace is very efficient, so heat pours into the house which warms us up every morning in the winter.

Last Question:

President Franklin Roosevelt once said,

“The coldest winter I ever spent was a summer in San Francisco.”

Answer:

No, Franklin Roosevelt never said this, but it is a great quote. Summers in San Francisco are cool and unruly. Most people do not know this and tourists who visit in the summer are usually in for a huge shock. I suspect sales of sweaters in San Francisco during the summer are brisk.
