What does high or low specific heat capacity mean? A substance with a high specific heat capacity can absorb a large quantity of heat before it will raise in temperature (water has a high specific heat). A substance with a low specific heat requires relatively little heat to raise its temperature (copper has a low […]
How long does a nuclear fuel rod last?
How long does a nuclear fuel rod last? To make that nuclear reaction that makes that heat, those uranium pellets are the fuel. And just like any fuel, it gets used up eventually. Your 12-foot-long fuel rod full of those uranium pellet, lasts about six years in a reactor, until the fission process uses that […]
What are some safety measures during severe bad weather changes?
What are some safety measures during severe bad weather changes? Stay indoors and move to a shelter – either an internal, ground-floor room with no windows or an official shelter nearby.

What products increase friction?
What products increase friction? There are two methods of increasing friction: one is by making the surfaces rough and the other by increasing the mass of the object that is moving. For example, the tyres of vehicles have treads (these are the ‘designs’ that you can see on the tyre surface), which increase the friction […]
What best compares radiation and conduction?
What best compares radiation and conduction? The statements that best compares radiation and conduction are the following: both transfer thermal energy from warm objects to cooler objects and both can transfer energy through matter. The difference is that conduction is through direct heat transfer; whereas, radiation transfers heat through waves. What describes how radiation moves? […]

Are peppered moths still black?
Are peppered moths still black? By 1970, in some polluted regions nearly 99 percent of peppered moths were now black. Still, scientists were puzzled as to how the black moths first came into being. Until now, that is. Researchers in England have traced the difference between a typica and carbonaria moth to a genetic tweak. […]
