Ask a ScienceBlogger: Evaporating Water
Posted by Rhett Allain on June 9, 2010 Here is another question from Ask a ScienceBlogger. Reader Uday Panta asks: How does water evaporate in the seas? Doesn’t water evaporate at 100 C? There were some very good responses in the comments where the question was, but I am going to answer it with some more details. Small Particle Model This is where…
Ask a ScienceBlogger: Drying dishes
Posted by Rhett Allain on June 7, 2010 As part of the Ask a ScienceBlogger series, reader Jim Swanson asks: When I open the dishwasher after washing and the contents are still hot, why do the glass and ceramic items dry off more quickly than the plastic items? This is a great question. Great because it is something most everyone can relate to…
Power source for a lightsaber

Thermal expansion of water in a pool
Posted by Rhett Allain on April 12, 2009 I already talked about increasing the temperature of a pool. My father commented that he thought the pool level rose by like half an inch when the temperature increased (by about 10 degrees F). So, this leaves the question: Is my father crazy, or is this possible? Or are both true?

Here is one such question (I can’t remember where I first found this question or something like it): Suppose you put take two identical cans of soda out of the…
Temperature – weirder than you think
Posted by Rhett Allain on March 6, 2009 Temperature is a pretty weird thing if you think about it. How do you best define temperature? Let me go ahead and give you my favorite definition: Temperature is the thing that two objects have in common when they have been in contact for a long time. Yes, that is a good definition. Maybe now…
Fetch with Ruff Ruffman uses a laser to measure temperature?
Posted by Rhett Allain on October 23, 2008 I am sorry to point this out, but I can’t help it. My kids watch this show “Fetch with Ruff Ruffman”. It’s mostly an ok kids show. However, there was a problem. In one episode, some kids were in the desert and measuring temperature with (they said it several times and it was even a…
